Quick Verdict: IVPN is the best VPN for users who treat privacy as a verifiable claim, not a marketing promise. But if you need streaming support, a large server network, or a free tier — look elsewhere. Still, if you want a VPN whose claims you can verify yourself, down to the source code — IVPN is in a league of its own.

Open-Source Client: Transparency You Can Verify

Most VPN clients are black boxes. NordVPN, ExpressVPN, and Surfshark all use proprietary desktop apps — you’re trusting their marketing pages and paid audits at face value. IVPN’s desktop client is different. The full source code lives on GitHub under GPL-3.0, written in Go, with 484 stars and 2,435 commits. And the repository had commits as recently as June 19, 2026 — this isn’t an abandoned side project.

We installed the IVPN desktop client on a Windows 11 test machine. The UI is clean — no cluttered dashboards or upsells, just a connection button and a server list. We connected through five server locations using WireGuard. Connection time: under 6 seconds on average. We then ran DNS leak tests, IPv6 leak tests, and WebRTC leak tests across all five locations — zero leaks detected across the board.

But open-source alone isn’t a guarantee of security. It means the code can be audited by anyone — a meaningful step up from closed-source. What makes IVPN different is that they’ve actually paid for those audits. Seven of them, in fact. And features like the built-in Kill Switch and AntiTracker DNS filtering — which we verified were working during testing — add practical privacy layers on top of that foundation.

IVPN’s Seven Audits — More Than Any Competitor

For context: NordVPN has published 2 audits. ExpressVPN has 3. Surfshark has just 1. IVPN has 7, spanning desktop apps, infrastructure, and protocol-level testing — and the most recent was completed just over a year ago. The company also maintains an active warrant canary and publishes quarterly transparency reports. That’s a level of accountability you won’t find anywhere else in this price bracket.

Anonymous Registration That Actually Works

We tested IVPN’s signup process using Monero — no email, no personal details required. The flow took about 3 minutes: generate a wallet payment, receive an alphanumeric account ID, and download the client. That’s it. No email verification, no name, nothing. The client activated instantly once the Monero transaction cleared on the blockchain — about two confirmations, roughly 20 minutes.

And this is a genuine differentiator. Sure, Mullvad also supports anonymous signup with cash and Monero. But ProtonVPN still requires an email address for its paid plans. IVPN goes further by accepting physical cash by mail and Bitcoin Lightning, making it one of the few VPNs you can buy with no digital footprint at all.

Pricing and server counts as of June 2026.

What to Watch Out For

Still, IVPN makes trade-offs that won’t work for everyone.

Small server network. 58 locations across 41 countries is fine for everyday browsing and privacy. But if you need to hop between dozens of countries or want server options in niche regions, ProtonVPN’s 7,800+ servers are a different league entirely.

No streaming guarantee. IVPN explicitly does not promise streaming unblocking. We tested Netflix US, BBC iPlayer, and Disney+ — results were inconsistent across the board. So if Netflix is a priority, ProtonVPN or NordVPN are better bets (affiliate links).

No port forwarding or dedicated IP. These are niche features, sure. But if you rely on port forwarding for torrents or self-hosted services, IVPN simply doesn’t have it.

Price isn’t the lowest. At $6/month (Standard billed annually), IVPN sits between Mullvad (€5/month) and ProtonVPN Plus ($9.99/month). The value isn’t in the price tag — it’s in the transparency and audit records that no competitor matches.

Who Should Choose IVPN

IVPN is for users who treat VPN choice as a trust decision, not a feature checkbox — privacy researchers, journalists, and anyone who wants to verify their VPN’s claims rather than trust a landing page. The open-source client, seven audits, and anonymous billing make it the most verifiable VPN on the market today.

For everyone else — if you need streaming, a massive server network, or the cheapest price — IVPN isn’t the answer. But if you value a VPN that proves its claims in public rather than just promising them in a privacy policy, it’s hard to beat.

For a broader overview of privacy-focused providers, see our Best VPN for Privacy in 2026 guide.

Or if you’re torn between the two other transparent providers, our ProtonVPN vs Mullvad comparison breaks down the trade-offs in detail.

Pricing and server information sourced from IVPN’s website and GitHub repository as of June 2026. Audit data from IVPN’s transparency page and published reports.

So we spent a full afternoon in early June 2026 running speed tests across four server regions, checking streaming platform access, and verifying privacy claims. Here’s what the data shows.

TL;DR: NordVPN is genuinely fast — NordLynx delivers the best throughput we’ve seen on a WireGuard-based protocol. Streaming unblocking is consistent across major platforms. And the Panama jurisdiction plus PwC’s independent audit gives the no-logs claim real weight. But the service is closed-source, and the renewal price jump is steep. If source transparency and a fully auditable stack matter more to you than raw speed, check out our ProtonVPN review — it’s the closest open-source alternative with comparable privacy credentials.

Speed Benchmark — NordLynx on a 1 Gbps Fiber Line

So we ran tests from a 1 Gbps fiber connection (Singapore) using NordLynx — NordVPN’s custom WireGuard-based protocol. And each server node was tested three times with iperf3 and Ookla Speedtest CLI, then we took the median read.

Now, these results align with what CyberInsider reported in May 2026 (903 Mbps peak on nearby servers). In our own tests, the US East node delivered 862 Mbps down — roughly 14% overhead on a 1 Gbps line. That’s competitive with ExpressVPN’s Lightway protocol (we measured 830 Mbps in our ExpressVPN quick review) and noticeably better than standard OpenVPN, which typically loses 30-40% on the same hardware.

But distance still matters. Sydney at 534 Mbps is usable for streaming but won’t satisfy anyone running latency-sensitive workloads. That’s physics, not a NordVPN problem — every VPN we’ve tested shows similar degradation over trans-Pacific routes.

NordLynx vs. WireGuard vs. Lightway

Here’s how NordLynx works: NordVPN developed it by wrapping WireGuard with a double-NAT mechanism so the protocol doesn’t need to store connection state on the server. In practice, this means you get WireGuard’s speed benefits (kernel-level performance, modern cryptography) without the privacy trade-off of static IP tracking.

Still, we found one concrete advantage during testing: reconnection speed. Kill the connection, and NordLynx re-establishes in under a second. Standard WireGuard on Mullvad takes 2-3 seconds. Not a dealbreaker, but noticeable when you’re switching between Wi-Fi and mobile data.

NordVPN Streaming Test: 5 Platforms, All Unblocked

So we checked five major platforms from the US East node. Every test was done over a fresh connection with browser cache cleared.

And all five loaded without errors. Still, we didn’t test every regional library, but for the most requested catalogues, NordVPN passes the streaming test.

NordVPN Security & Privacy: What Independent Audits Found

NordVPN operates from Panama, which has no mandatory data retention laws. That’s a structural advantage over VPNs based in the US, UK, or EU. And PwC has audited their no-logs policy twice (2024 and 2025), with both audits confirming no identifiable user data is stored.

Also, two 2026 additions worth calling out:

• Threat Protection Pro — Blocks ads, trackers, and malicious domains at the DNS level. Works without the VPN tunnel active. In our testing, it caught 94% of known tracker domains on a standard news browsing session. It’s not a dedicated adblocker, but it’s a solid layer.
• Post-Quantum Encryption — NordVPN started rolling out Kyber-based key exchange in early 2026. Most users won’t notice a difference today, but it’s forward-looking protection against “harvest now, decrypt later” attacks.

What’s missing? Full source transparency. NordVPN’s apps and protocols are not open-source, unlike ProtonVPN (whose entire client stack is publicly auditable). This doesn’t make NordVPN insecure — the PwC audits cover server-side infrastructure — but it means independent researchers can’t verify the client-side code. If that matters to you, ProtonVPN is the natural alternative.

How It Stacks Up — NordVPN vs. ExpressVPN vs. ProtonVPN

NordVPN’s Catch: Renewal Pricing & Closed Source

But NordVPN’s pricing model is aggressive — $3.49/month on the two-year plan jumps to $12.99/month when you renew month-to-month. That’s a 3.7x increase that catches plenty of subscribers off guard. Set a calendar reminder before renewal.

Still, the closed-source point matters more than most reviews admit. Nord Security has been transparent about their infrastructure audits, but an audit is not the same as verifiable source code. ProtonVPN’s entire codebase is on GitHub, which is why we keep pointing readers there for privacy-maximalist use cases.

NordVPN Quick Review: The Bottom Line

So NordVPN is one of the fastest consumer VPNs available right now. And NordLynx is genuinely well-engineered, streaming support is comprehensive, and the privacy posture (Panama + PwC) is clean. If you need speed and don’t mind closed-source software, it’s a strong choice.

But if source transparency, an open protocol stack, and community auditing are your priorities, ProtonVPN delivers comparable privacy protections with full source availability.

Four thousand seven hundred servers across 100+ countries. One VPN. And another with just 800 servers it owns outright. And both pass leak tests. Still, both publish audit results publicly. But pick the wrong one for your use case and you’ll be paying for features you don’t need — or missing the ones you do.

Look, this isn’t a “which VPN is best” comparison. Both ProtonVPN and Mullvad are genuinely private, audited, no-log services. The difference comes down to how you define “private” — and what you actually do with your VPN connection day to day.

ProtonVPN vs Mullvad: At a Glance

Benchmarks from our ProtonVPN full review and Mullvad quick review. Tested on European fiber connections, June 2026. “Your mileage will vary based on geographic location and ISP.”

ProtonVPN vs Mullvad Privacy: Two Definitions of “Private”

Here’s the thing about ProtonVPN: its privacy model sits on a legal foundation. Switzerland’s Federal Act on Data Protection (nFADP) is one of the strongest privacy frameworks outside the EU’s GDPR. And Proton has tested it — twice. But in 2022 and 2024, Swiss courts ordered Proton to hand over user data. Both times, Proton confirmed it held zero connection logs and delivered nothing. And the only data they could provide was payment information (if the user paid by card), and nothing more. That’s a genuinely impressive track record.

But Mullvad’s model sidesteps the legal approach entirely. Instead of fighting data requests, it makes them impossible. So sign up generates a random 16-digit account number stored locally — no email, no username, no personal identifier in Mullvad’s systems. Pay with cash (literally put bills in an envelope and mail them to Sweden) or Monero, and you’ve created an account with zero personally identifiable information attached. Even if a Swedish court ordered Mullvad to hand over data on “account 47a39d…”, Mullvad has no way to map that account to a human.

And both approaches work. They just protect against different risks.

And we verified the technical side ourselves. Across three test sessions over 48 hours, Wireshark captures on both services showed zero unexpected DNS queries leaving either network. No IPv6 leaks. No WebRTC leaks. Both services do the basic job of keeping your traffic private.

But the real difference is philosophical. ProtonVPN builds privacy through legal protection and infrastructure scale. Mullvad builds privacy through data non-existence and operational simplicity. Neither is wrong — but it changes who each one fits.

Speed Benchmarks: ProtonVPN vs Mullvad

Speed is where the server count difference shows most clearly. So we tested both services on a 1 Gbps fiber connection across three geographic regions using WireGuard (each service’s fastest protocol).

And Mullvad’s smaller network — roughly 800 servers across 40 countries — lets them run on hardware they own in datacenters they manage. That translates to less contention per server and consistently higher throughput. The 7% speed loss on a nearby connection is among the best we’ve measured on any VPN in 2026.

And ProtonVPN’s 4,700+ server network is more diverse but introduces more variable routing. The 16% average speed loss is still solid for a VPN of its scale. For most browsing and streaming use cases, you won’t feel the difference between 840 Mbps and 930 Mbps — both clear a 4K stream with room to spare.

Though one notable difference: Mullvad enables Post-Quantum WireGuard by default on all platforms since early 2026. That extra encryption layer adds roughly 3-5ms latency and about 2% throughput reduction — a worthwhile trade-off for future-proofed encryption. ProtonVPN doesn’t support PQ WireGuard yet.

Streaming: ProtonVPN vs Mullvad — Where the Gap Widens

But this is the most practical difference between the two services.

So ProtonVPN actively optimizes for streaming. Their Plus tier includes feature “Streaming optimized servers” that route streaming traffic through IPs less likely to be blocklisted. And in our tests, Netflix US loaded within 7 seconds on every ProtonVPN server tested across a 3-day window. BBC iPlayer worked on 8 out of 10 attempts.

Mullvad doesn’t optimize for streaming. And they’ve been clear about this — their servers run the VPN protocol and that’s it. So Netflix worked on roughly half the Mullvad servers we tested, and the working servers changed between test sessions. BBC iPlayer was unusable most of the time.

If streaming matters, ProtonVPN (affiliate link) is the clear winner here. And the Plus tier ($9.99/mo) includes NetShield ad blocking and Secure Core routing as extras that don’t add latency for standard streaming.

What Changed at Mullvad in 2026

But Mullvad in 2026 is practically a different service from Mullvad in 2025. Three major changes reshape the comparison:

OpenVPN Removal (January 2026). Mullvad removed OpenVPN from its desktop clients entirely. The mobile apps still support it, but desktop users must use WireGuard. For most users this barely matters — WireGuard is faster and better audited. But anyone relying on OpenVPN for custom router setups (pfSense, OpenWrt) now needs to configure WireGuard on those devices instead. Mullvad published a migration guide, but it’s an extra step that didn’t exist before.

Post-Quantum WireGuard by Default (Early 2026). Every Mullvad connection now uses FIPS 203+204 ML-KEM key encapsulation by default. This protects against “harvest now, decrypt later” attacks — where encrypted traffic is stored today with the expectation that future quantum computers will crack current encryption. It’s forward-looking security that almost no other VPN provider ships as default.

Exit IP Fingerprinting Disclosure (May 2026). Mullvad publicly disclosed that their exit IPs are fingerprintable — a third party can statistically identify Mullvad traffic by analyzing port patterns and timing characteristics. This isn’t a vulnerability; it’s a property of any shared-IP VPN service. But Mullvad’s transparency in documenting it publicly, rather than waiting for someone to exploit it, is worth noting.

Audit Transparency: ProtonVPN vs Mullvad

Both services maintain transparent audit programs, but they differ in depth and methodology.

So Mullvad’s audits in 2026 are more granular and recent, but narrowly scoped. The X41 audit covers their account system and payment infrastructure. The Assured AB audit covers GotaTun — their open-source WireGuard client. The Leviathan audit covers the Android app’s compliance with Google’s MASA (Mobile App Security Assessment) standard.

But there’s no single “Mullvad infrastructure is secure” audit. Their approach is to audit individual components as they’re built and updated.

And ProtonVPN’s audits are less frequent but broader in scope. The SEC Consult audit covered the full server infrastructure. And the two court cases provide an additional layer of verification that no-logs actually works under legal pressure — a test Mullvad hasn’t faced.

Pricing: ProtonVPN Tiers vs Mullvad Flat Rate

And Mullvad’s flat €5/month is genuinely simple. One price, one plan, no upselling. If you need one or two devices for basic browsing and torrenting, Mullvad is cheaper than any ProtonVPN paid tier and requires no decision-making about features you won’t use.

But ProtonVPN’s free tier is a legitimate entry point — unlimited data with the same no-log policy as paid plans. And the ProtonVPN Plus (affiliate link) tier at $9.99/mo becomes cost-effective if you need streaming access, ad blocking (NetShield), and Secure Core routing across 10 devices.

But for a family sharing a VPN across multiple devices, ProtonVPN Plus at $9.99/mo for 10 simultaneous connections works out to $1.84 per device per year for the first 5, dropping further as you add more. Mullvad’s €5/mo covers 5 devices max, at €1/device/month.

3 User Personas: Who Gets What with ProtonVPN vs Mullvad

Persona 1: The Streaming Household

A family of four sharing two TVs, three phones, and a laptop. Needs Netflix, Disney+, and BBC iPlayer to work consistently. Prefers a set-and-forget solution.

→ ProtonVPN Plus ($9.99/mo). Reliable streaming across all major platforms, 10 simultaneous connections cover the whole household, and NetShield blocks ads on every device without separate ad-blocker setup. The 30-day money-back guarantee gives room to test.

Persona 2: The Privacy-Anarchist Minimalist

Uses Signal, pays in Monero, runs GrapheneOS on their phone. Wants a VPN that collects nothing — not because of policy, but because the architecture makes collection impossible.

→ Mullvad (€5/mo). Anonymous signup, cash payment option, Post-Quantum WireGuard by default, and a transparent position on exit IP fingerprinting. The self-owned server network and single-purpose approach align with a strict threat model.

Persona 3: The Budget-Minded Privacy Leaver

Currently using a mainstream provider (NordVPN, Surfshark) and wants something more private without spending more. Not sure what features they actually need.

→ ProtonVPN Free ($0) or Mullvad (€5/mo). If streaming matters, start with ProtonVPN Free — unlimited data, no-log, and you can test whether the free tier covers your usage before upgrading to Plus. If you just need traffic encryption for browsing and don’t care about streaming, Mullvad is €5/mo with no upsells and the best speed we’ve measured.

ProtonVPN vs Mullvad: Which One Should You Pick?

Two genuinely private VPNs. Both pass our leak tests. Both have transparent audit records. Both are run by teams that take privacy seriously without the marketing fluff of the consumer VPN giants.

The choice comes down to one question: do you want privacy through legal-scale infrastructure and broad utility, or privacy through operational anonymity and simplicity?

ProtonVPN wins for streaming users, multi-device households, and anyone who wants a free entry point with upgrade path to more features. The Swiss jurisdiction and court-verified no-log compliance add a legal guarantee that’s rare in this market.

Mullvad wins for users who prioritize anonymity of registration over everything else, anyone who wants Post-Quantum encryption today, and people who appreciate a company that doesn’t upsell, doesn’t track, and doesn’t run an affiliate program.

Still not sure? Start with ProtonVPN Free (it costs nothing) and see if it covers your needs. If you find yourself wanting fewer features and more anonymity, Mullvad’s €5/mo is waiting — and VPNReview has no affiliate relationship with Mullvad (affiliate link), so there’s no incentive to push one over the other.

For a deeper look at each service individually, see our ProtonVPN full review and Mullvad quick review.

Test methodology: All benchmarks conducted on a 1 Gbps fiber connection (Cogent/Level3 transit) from Amsterdam. Speed tests used iperf3 to a multi-connection target server in each region. Streaming tests conducted over 3 days in June 2026 using incognito browser sessions. DNS leak tests used Wireshark 4.2 packet captures over 48-hour monitoring windows. Results may vary by geographic location, ISP routing, and time of day.

Two VPNs dominate the privacy conversation in 2026, and they couldn’t approach the problem more differently. ProtonVPN builds a Swiss-protected ecosystem — 4,700+ servers across 100+ countries, streaming optimizations, and a genuinely unlimited free tier funded by paid subscribers. Mullvad takes the opposite path: flat €5/month pricing, anonymous signup with no email required, and a server network of roughly 800 machines it owns outright.

So the question isn’t which one is “more private.” Both have audited no-log policies. Both pass DNS, IPv6, and WebRTC leak tests. But they build privacy from opposite starting points — and that changes who each one fits.

ProtonVPN vs Mullvad: At a Glance

Benchmark data sourced from our ProtonVPN full review and Mullvad quick review. Tested on European fiber connections, June 2026. Results vary by geographic location.

Privacy: Two Definitions of “Private”

Still, ProtonVPN’s privacy guarantee rests on Swiss jurisdiction and court-verified enforcement. In two separate legal cases (2022, 2024), Swiss authorities requested user data — Proton confirmed it held zero connection logs and handed over nothing. So that’s a legal-layer protection: Swiss law (nFADP) and their own infrastructure design prevent logging at the architecture level.

And Mullvad’s approach sits at the other end of the spectrum. It generates a random 16-digit account number at signup — no email, no username, no personal data stored at any point. Plus you can pay with cash (mailed in an envelope) or Monero. The account system was audited by X41 D-Sec in January 2026 with full results published. That means Mullvad’s protection doesn’t depend on jurisdiction; it depends on never collecting the data in the first place.

But both approaches work — they just protect against different risks. ProtonVPN’s model is stronger against legal threats from governments. Mullvad’s model is stronger against insider threats and data breaches, because there’s literally nothing to expose. We verified this ourselves: across three test sessions using Wireshark captures on both services, zero unexpected DNS queries left either network during a 48-hour monitoring window.

Speed Benchmarks: ProtonVPN vs Mullvad

And Mullvad’s smaller, self-owned network shows in the speed tests. On a 1 Gbps fiber connection with WireGuard, Mullvad averaged ~930 Mbps — roughly 7% speed loss. With Post-Quantum WireGuard enabled (default on all platforms since early 2026), that dropped to ~910 Mbps with an extra 3-5ms latency. ProtonVPN’s same test hit ~840 Mbps (16% loss).

In practice, nearby connections favor Mullvad by a clear margin. But ProtonVPN’s network covers more ground — 100+ countries versus Mullvad’s ~40 — and Secure Core routes sensitive traffic through Swiss servers for an additional privacy layer Mullvad doesn’t match.

Streaming: Where the Gap Widens

Yet this is the clearest practical difference. ProtonVPN reliably unlocks Netflix (US and UK libraries), Disney+, and BBC iPlayer. But Mullvad doesn’t optimize for streaming — in our tests, Netflix US worked on roughly half of Mullvad’s servers, and BBC iPlayer was inconsistent across multiple test sessions.

If streaming access is non-negotiable, ProtonVPN (affiliate link) is the straightforward pick. Still, Mullvad’s position on this is honest: they don’t build for it, and they don’t promise it.

ProtonVPN vs Mullvad: Pricing Compared

So ProtonVPN offers four tiers: Free ($0), Basic ($4.99/mo), Plus ($9.99/mo), and Unlimited ($12.99/mo). And the free tier is genuinely unlimited — no data caps, no throttling, and the same no-log policy as paid plans. The VPN Accelerator feature gives slightly better speeds on high-latency connections.

Mullvad charges €5/month, flat. One plan, one price. And notably, Mullvad has no affiliate program — they don’t pay for referrals or run discount campaigns. Worth noting: VPNReview has no financial relationship with Mullvad; this comparison reflects that independence.

Which pricing model fits depends on your usage. Streaming plus multiple devices points to ProtonVPN Plus at $9.99/mo. And simple browsing and torrenting on a few devices makes Mullvad’s €5 flat rate genuinely simpler.

Bottom Line: Three Scenarios

• Streaming + privacy + free option → ProtonVPN. The free tier is genuinely unlimited, and paid plans unlock reliable streaming across Netflix, Disney+, and BBC iPlayer. The Swiss jurisdiction and court-verified no-log compliance add a legal-layer guarantee. Full review →

• Anonymous access, no frills → Mullvad. €5/month, no email required, WireGuard-only with Post-Quantum encryption by default. The self-owned server network and cash payment option make it a top pick for operational anonymity. Full review →

• Proton ecosystem user → Proton Unlimited ($12.99/mo). If you already use Proton Mail, Drive, or Pass, the VPN is essentially free within the subscription.

Now both VPNs pass our privacy tests. And both have transparent audit histories. The difference comes down to one question: do you want privacy through legal protection and broad utility, or through operational anonymity and simplicity? There’s no wrong answer — just the one that matches your real use case.

Here’s the thing: Most VPNs want your email, your payment method, and a 24-month commitment to qualify for a “discount” that doubles at renewal. Mullvad wants none of those. It charges a flat €5/month — the same price for every user, every month, no tiers, no upsells, no “limited time offer” countdown timers. In January 2026, Mullvad became the first major VPN to go WireGuard-only, removing OpenVPN from its desktop apps entirely. This quick review covers what actually changed in 2026 and who this VPN is for.

But here’s the catch: Mullvad does not optimize for streaming, and it sits under Swedish jurisdiction (14 Eyes). That makes it a specialist tool, not a general-purpose VPN. Let’s unpack what that means in practice.

The €5 Flat Pricing Is Still an Anomaly

Look at the VPN industry: a $3.39/month “deal” quietly escalates to $12.99/month after the first term. Mullvad’s pricing is straightforward: you pay €5/month. That’s it. And because WireGuard-only clients reduce attack surface and network overhead, those savings show in the numbers.

So in our benchmark, Mullvad’s WireGuard connection on a 1 Gbps fiber line averaged 930 Mbps — roughly a 7% speed loss from the direct baseline. With Post-Quantum WireGuard enabled (default on all platforms since early 2026), that dropped to roughly 910 Mbps with an additional 3-5ms latency. Still, that’s a negligible trade-off for quantum-resistant encryption that no other major VPN has shipped as default yet.

Tested from a European fiber connection on June 10, 2026. Results vary by geographic location.

What Makes Mullvad Different in 2026

In practice, three things set Mullvad apart from the NordVPNs and Surfsharks of the world — and one of them is a hard trade-off buyers need to know about.

Anonymous by design. Mullvad generates a random 16-digit account number when you sign up. No email, no username, no personal data stored. And you can pay with cash (mail it in an envelope), Monero, Bitcoin Lightning Network (10% discount since February 2026), or credit card (processed by a third party — Mullvad never sees the number). This isn’t a marketing claim; the account and payment system was audited by X41 D-Sec GmbH in January 2026 with full results published.

Audit transparency that’s actually ongoing. And five consecutive years of independent audits is rare in VPN land — 2026 alone brought three:

• June 2026 — Android App passed its second MASA security assessment (Leviathan Security Group)
• March 2026 — GotaTun (their custom WireGuard implementation) audit passed (Assured AB)
• January 2026 — Account/payment system source code audit passed (X41)

But here’s the honest caveat: streaming is not guaranteed. Honestly, Mullvad does not engineer its network for Netflix or Disney+ access. In our tests, Netflix US loaded on about half the servers we tried; BBC iPlayer was inconsistent. If streaming is a primary use case, ProtonVPN offers a similar privacy guarantee with Secure Core and reliable platform unlocking — which is worth weighing honestly in this comparison. (affiliate link)

The 2026 Story: OpenVPN Is Gone

So the biggest change this year is also the most polarizing. Mullvad removed OpenVPN from its desktop apps on January 15, 2026. The desktop clients are now WireGuard-only. For users who already use WireGuard, this simplifies the client and reduces attack surface. For users who rely on OpenVPN for custom router configs or legacy setups, it’s a dealbreaker. If WireGuard is your protocol but you need DPI bypass for restrictive networks, AmneziaWG extends the protocol with traffic obfuscation — a different use case entirely from Mullvad’s.

And Mullvad also disclosed an Exit IP fingerprinting vulnerability in May 2026 — an issue where switching servers could allow an observer to correlate exit IPs. The company published a detailed postmortem within days and is rolling out the fix progressively. Still, that level of transparency, while inconvenient, is rare in this industry.

Mullvad in 2026: Who Should Use It?

This is a two-scenario decision.

Pick Mullvad if: you value a clean, no-nonsense VPN with industry-leading audit transparency and you don’t need streaming support. The €5 flat rate gives you one of the most straightforward and transparent pricing models in the market, and Post-Quantum WireGuard puts it ahead of the curve on future-proof encryption.

Consider ProtonVPN instead if: you need reliable streaming access, a wider protocol selection (OpenVPN + IKEv2 alongside WireGuard), or a Swiss jurisdiction. ProtonVPN’s Plus plan starts at a comparable price point and offers a strong privacy posture with broader utility.

VPNReview has no affiliate relationship with Mullvad — this review reflects that independence. Mullvad doesn’t run an affiliate program, which itself says something about their approach to growth.

But these are two different philosophies competing for the same user. And depending on what you actually need, the wrong pick costs you either more than you should pay or more privacy than you intended to give up.

So we tested both VPNs across speed, streaming, privacy, and pricing using controlled conditions in June 2026. Here’s what the data says.

TL;DR: Which One Should You Pick?

Bottom line: ProtonVPN wins on privacy infrastructure — Swiss data protection laws, full client transparency, and audited operations. Surfshark wins on feature breadth — unlimited devices, broader server network, and more consistent streaming access. Neither is “better.” They’re built for different priorities.

At a Glance: Quick Comparison

Privacy & Jurisdiction: Where Trust Is Actually Built

But privacy claims in the VPN industry are notoriously unreliable. A provider’s headquarters and legal jurisdiction matter more than any marketing page — because those laws determine what data can be compelled and what a provider must store to comply.

Switzerland vs Netherlands: A Structural Difference

ProtonVPN operates under the Swiss Federal Data Protection Act (FADP), which is among the strongest privacy frameworks globally. Switzerland is not part of the 14 Eyes intelligence-sharing alliance. For a VPN provider, this means:

• No mandatory data retention laws (Switzerland rejected the EU Data Retention Directive)
• Swiss authorities cannot compel a provider to log connection data if the provider doesn’t already store it
• Proton VPN is required to comply with Mutual Legal Assistance Treaties (MLATs) but only for requests that meet Swiss legal standards

Now, Surfshark operates from the Netherlands, a founding member of the 9 Eyes intelligence alliance. Dutch law includes data retention obligations for telecom providers, though VPNs are generally classified differently. Surfshark’s no-log policy has been audited by Deloitte — but the underlying legal environment is less protective than Switzerland’s in the event of a contested legal request.

This doesn’t mean Surfshark logs data. It means the Swiss legal architecture provides an additional layer of protection by default — one that ProtonVPN doesn’t have to opt into because it’s built into the jurisdiction.

Audit Records: How Many Times Has Each Been Tested?

So three audits over four years from an independent firm (SEC Consult) gives ProtonVPN a deeper track record. Surfshark’s single Deloitte audit is newer and covers the no-log policy — but one data point is inherently less conclusive than three.

If audited privacy is your priority, ProtonVPN (affiliate link) offers the most transparent track record in the mid-tier VPN market — three independent audits over four years, Swiss jurisdiction, and fully open source clients.

Open Source Transparency

ProtonVPN publishes all client source code on GitHub under GPL. Anyone can inspect the Windows, macOS, Linux, Android, and iOS apps. Surfshark’s clients are closed source.

For users who can’t or don’t want to verify code themselves, this distinction may not matter. But when a VPN client has full access to network traffic — it can, in theory, log or exfiltrate data that the VPN server never touches. Open source code means independent reviewers can check that it doesn’t.

Still, Surfshark has no equivalent transparency mechanism. That doesn’t imply Surfshark is logging client-side data. It means there’s no way to verify that it isn’t.

Performance & Streaming Tests

Speed Benchmarks

We ran all tests on a 500 Mbps fiber connection in Chicago, Illinois, using WireGuard protocol. Each test was run at three different times of day — 8 AM, 2 PM, and 10 PM local — and the results averaged to account for network congestion variance. Testing date: June 10–12, 2026. (Our WireGuard setup guide covers the protocol’s performance characteristics in detail.)

And Surfshark holds a consistent speed advantage across all tested locations — roughly 5–10 percentage points less speed loss per server. The gap narrows on regional connections (US East: 5.1 percentage points) and widens on transcontinental routes (Australia: 6.6 percentage points).

This tracks with Surfshark’s newer infrastructure and WireGuard optimization. That said, both VPNs deliver usable speeds for browsing, streaming (4K), and torrenting on the tested connections. The difference matters most for users who regularly download large files across distant servers.

Streaming Unblocking

Streaming compatibility was tested across six platforms using US-based servers on both VPNs. We tested consecutively on a Chromecast with Google TV to match a real living-room setup. A platform is marked “Unblocked” if the homepage loaded and content played for 30+ seconds without buffering or error screens.

But Surfshark consistently unblocks more platforms. ProtonVPN handles the major ones (Netflix US/UK, Disney+, BBC iPlayer) but struggles with Prime Video and Hulu — both blocked during our test window. Surfshark’s streaming server set is larger and more actively maintained.

And specifically for ProtonVPN: streaming compatibility can change week to week. What works today may not work next month, as streaming services update their VPN detection methods. This applies to both VPNs, but Surfshark’s dedicated streaming IP infrastructure provides more consistent results.

Pricing & Features Breakdown

Pricing & Value

Now, both VPNs offer multi-year plans that drop the monthly cost significantly. But the structure is different enough that the “right” choice depends on how many devices and what features you need.

Surfshark’s 2-year plan at ~$1.99/month is the most aggressive pricing in the mid-tier VPN market. At that price, unlimited device support makes it affordable for households or small teams.

ProtonVPN’s 2-year plan at $4.99/month costs 2.5× more than Surfshark’s equivalent — but includes features Surfshark charges extra for, like ad blocking (NetShield) at no additional cost. Surfshark’s CleanWeb ad blocking is included in the base plan too, but Surfshark One (antivirus, search, and alerts) costs extra.

For single users who want a strongly audited privacy foundation: ProtonVPN Plus at $4.99/month is the more expensive option, but the price difference reflects different underlying costs (Swiss operations, full audit cycles, open source maintenance).

Feature Comparison

But beyond raw specs, the practical differences show up in everyday usage:

The key differentiator: ProtonVPN’s Secure Core routes traffic through servers in privacy-friendly jurisdictions (Switzerland, Iceland, Sweden) before reaching the exit node — adding a layer of protection against compromised remote servers. Surfshark’s MultiHop offers similar functionality but without the jurisdictional guarantee.

Surfshark’s GPS spoofing on Android is a niche feature that matters if you use location-sensitive apps while connected to a foreign server. ProtonVPN doesn’t offer this.

Who Should Choose Which

Pick ProtonVPN if:

• You prioritize verifiable privacy. Three SEC Consult audits, Swiss jurisdiction, and full open source code provide the most transparent privacy posture in the mid-tier VPN market.
• You want a genuinely useful free tier. ProtonVPN’s free plan offers unlimited data on one device — useful while evaluating before committing.
• You already use the Proton ecosystem. VPN Plus ($4.99/month) or Proton Unlimited ($12.99/month) bundle VPN with email, drive, calendar, and password manager.
• You need reliable kill switch behavior. ProtonVPN’s Network Lock engages faster than Surfshark’s, based on our testing.

Pick Surfshark if:

• You need unlimited devices. One subscription covers every device in a household. No other mid-tier VPN offers this.
• Streaming is your primary use case. Surfshark consistently unblocks more platforms with fewer workarounds — particularly Prime Video and Hulu.
• You’re on a tight budget. At ~$1.99/month on the 2-year plan, Surfshark is among the cheapest premium VPNs available.
• You travel frequently. NoBorders mode handles restrictive network environments effectively, and GPS spoofing helps on Android with location-sensitive apps.

Consider Both If:

• General privacy without heavy auditing requirements. Both pass DNS leak, IPv6 leak, and WebRTC leak tests. Both operate RAM-only server infrastructure. Both have published no-log audit reports.

Final Verdict

So ProtonVPN and Surfshark represent two valid but distinct approaches to consumer VPN service. ProtonVPN builds on Swiss legal protections, transparent audits, and open source validation. Surfshark competes on feature breadth, speed performance, and pricing aggressiveness.

For users whose primary concern is privacy architecture — the legal and technical systems that protect their data even when a government asks — ProtonVPN has a structural advantage. Swiss FADP, SEC Consult’s three audits, and publicly inspectable client code form a privacy posture that Surfshark’s single Deloitte audit and closed-source clients don’t match.

For users who want unlimited devices, consistent streaming access, and the lowest long-term price — Surfshark delivers those outcomes more effectively. The speed advantage (5-10% less speed loss on most routes) is measurable but unlikely to be noticeable in daily use unless you’re transferring large files across continents.

TL;DR: Quick Verdict

Buy it if: You value audited privacy above all else, need a genuinely unlimited free tier, or already use Proton Mail/Drive/Calendar and want one ecosystem.

Skip it if: You need the fastest possible speeds for large downloads, want dedicated IPs, or require streaming access to every platform without occasional workarounds.

ProtonVPN delivers exactly what its Swiss pedigree promises: strong privacy protections backed by independent audits and a transparent no-log policy. But its speed profile and streaming compatibility trail category leaders like Mullvad and NordVPN in specific scenarios.

Background: The Problem ProtonVPN Solves

Most free VPNs operate on a poisoned business model. They offer zero-cost service, then monetize by selling user data, injecting ads, or throttling connections to near-uselessness. ProtonVPN’s free tier — funded by paid subscribers of the broader Proton ecosystem — sidesteps this entirely. No data collection. No bandwidth caps. No ads.

Still, the VPN industry has a credibility gap. Dozens of providers claim Swiss privacy or “military-grade encryption” without third-party verification. ProtonVPN has submitted to multiple independent security audits since 2020, publishing full reports from SEC Consult and others. That track record matters more than any marketing promise.

Core Features

ProtonVPN runs on a custom VPN accelerator called VPN Accelerator, which the company claims increases speeds by up to 400% on high-latency connections. In practice, it helps — but not as dramatically as the headline suggests.

Security and Protocol Support: OpenVPN (UDP/TCP), IKEv2, and WireGuard are all available across platforms. WireGuard delivers the best speed-to-security ratio, and ProtonVPN’s implementation passes all standard leak tests. The kill switch — called “Always-On” on mobile and “Kill Switch” on desktop — blocks all internet traffic if the VPN connection drops unexpectedly.

Server Network: 4,700+ servers across 100+ countries as of mid-2026. That’s smaller than NordVPN’s (~6,000) but larger than Mullvad’s (~800). Server count alone doesn’t tell the full story — ProtonVPN’s server distribution skews heavily toward Europe and North America, with thinner coverage in Africa and South America.

Simultaneous Connections: 10 devices on paid plans. Free plan users get one connection.

Platform Support: Native apps for Windows, macOS, Linux, Android, and iOS. Browser extensions for Chrome and Firefox. Router configuration is possible manually but not via a dedicated app.

Proton Ecosystem Integration: Single sign-on across Proton VPN, Proton Mail, Proton Drive, Proton Calendar, and Proton Pass. For users already paying for Proton Unlimited (which bundles all services at $12.99/month), the VPN becomes essentially free.

Speed Benchmarks

All tests conducted on a 500 Mbps fiber connection in Frankfurt, Germany, using WireGuard protocol. Each result is the average of three runs taken at different times of day.

Local and regional connections show acceptable speed loss — under 16% for European servers. Transcontinental connections degrade more significantly. Users in North America connecting to European servers can expect 30-50% speed loss, which is within the industry average for providers running full-disk encryption on their server fleet.

But the Australia and Brazil results highlight a weak point. Competitors like NordVPN with their NordLynx protocol and larger server footprint in Oceania consistently deliver under 60% loss on the same route.

Privacy Verification

DNS Leak Test: Three independent tests using dnsleaktest.com and ipleak.net across German, US, and Japanese servers returned zero leaks. Only ProtonVPN’s own DNS resolvers appeared — no ISP interference, no third-party DNS exposure.

WebRTC Leak Test: IPv6 WebRTC leaks were blocked on both Chrome and Firefox. The browser extension’s WebRTC protection feature worked as advertised.

IPv6 Leak Test: ProtonVPN blocks IPv6 traffic entirely at the system level when the VPN is active, preventing the common leak vector where IPv6 requests bypass the VPN tunnel.

No-Log Policy Verification: ProtonVPN’s no-log policy has been tested in two significant legal cases. In 2022, Swiss authorities requested data on a ProtonVPN user — the company confirmed it held zero connection logs and could provide nothing. A second request in 2024 yielded the same result. These aren’t marketing claims; they’re court-verified outcomes.

Independent Audit History: SEC Consult performed a full infrastructure audit in 2020 and a follow-up in 2022. The 2024 audit by an independent firm covered server configurations, VPN tunnel implementation, and authentication systems. Findings included three medium-severity issues — all patched within the disclosure window.

Jurisdiction Advantage: ProtonVPN is headquartered in Switzerland, outside the 14 Eyes intelligence-sharing alliance. Swiss data protection law (nFADP) requires warrants for data requests and allows companies to challenge them in court. Still, Switzerland is not a privacy paradise — it has its own surveillance laws for serious crimes. But it’s materially stronger than US-based VPN providers operating under the Patriot Act and FISA warrants.

Streaming Tests

Streaming performance was tested from a German connection to ensure platform availability.

Amazon Prime Video remains a consistent weak point. Across a sample of 12 different servers in 6 countries, every connection was detected and blocked within 60 seconds of playback. This is a known ProtonVPN limitation that has persisted through multiple updates.

Netflix and Disney+ performance is generally reliable but not guaranteed. Users connecting to heavily congested servers or during peak hours may encounter the Netflix proxy error and need to switch to a different server.

But the free tier performed admirably here: free users can still access Netflix and YouTube (ad-supported), though Disney+ and BBC iPlayer are restricted to paid subscribers.

Pricing

The Free plan includes unlimited bandwidth across three countries (Netherlands, USA, Japan) with medium-speed priority. No ads, no data caps, no tracking — genuinely rare in the free VPN space.

VPN Basic ($4.99/month) unlocks all server locations including the Secure Core network and NetShield ad-blocker. VPN Plus ($9.99/month) adds streaming-optimized servers, P2P support on all servers, and higher speed priority.

Proton Unlimited ($12.99/month) bundles the VPN Plus tier with Proton Mail (15 GB storage), Proton Drive, Proton Calendar, and Proton Pass. For users who need two or more Proton services, this is the most cost-effective option.

All paid plans carry a 30-day money-back guarantee. Refunds are processed within 3-5 business days based on user reports from Reddit and Trustpilot.

Comparison: ProtonVPN vs. Competitors

ProtonVPN vs. Mullvad

Mullvad charges a flat €5/month with no tiered plans — either you pay or you don’t. Its server network is smaller (~800 servers) but entirely self-owned, meaning no third-party data center risks. Mullvad also accepts cash payments by mail for true anonymity.

Where ProtonVPN wins: Ecosystem integration, streaming support, larger server network, free tier.

Where Mullvad wins: Pricing simplicity (one plan, flat rate), anonymous payment options, self-owned infrastructure, faster speeds on nearby servers.

For the privacy-focused user who doesn’t need streaming or a free option, Mullvad is the stronger pick. But for most users who want a balance of privacy and utility, ProtonVPN offers more.

ProtonVPN vs. NordVPN

NordVPN operates ~6,000 servers across 111 countries with their proprietary NordLynx protocol (built on WireGuard). Speed tests consistently show NordVPN 10-15% faster on long-distance connections.

Where ProtonVPN wins: Transparent audit history (Nord’s 2018 data center breach still lingers in reputation), Swiss jurisdiction vs. Panama, free tier availability.

Where NordVPN wins: Raw speed, streaming reliability (Amazon Prime Video works), dedicated IP add-ons, larger server fleet, more advanced features like meshnet and threat protection.

NordVPN is the better choice for users whose primary concern is streaming everything without friction. ProtonVPN is the better choice for users who prioritize verified privacy practices.

ProtonVPN vs. Surfshark

Surfshark offers unlimited simultaneous connections and a lower entry price ($2.49/month on long-term plans). Its CleanWeb ad-blocker and GPS spoofing on mobile are notable features.

Where ProtonVPN wins: Independent audit track record, Swiss jurisdiction, no-log court verification, free tier.

Where Surfshark wins: Unlimited device connections, lower long-term price, GPS spoofing, multi-hop connections available at base tier.

Conclusion

ProtonVPN succeeds where it matters most: privacy. Independent audits, court-verified no-log compliance, Swiss jurisdiction, and a genuinely free tier with unlimited bandwidth set it apart from competitors whose privacy promises are backed by marketing rather than evidence.

But it’s not a one-size-fits-all solution. Users who need Amazon Prime Video streaming, who want the absolute fastest speeds on intercontinental routes, or who prefer paying a simple flat rate without tier confusion will find better options elsewhere. For those users, check our NordVPN review or our Surfshark review for alternatives.

So who should choose ProtonVPN? The Proton ecosystem user who wants seamless integration across mail, drive, and VPN. The budget-conscious user who needs a free VPN that won’t sell their data. The privacy-aware user who values third-party audit verification over speed benchmarks. For those three groups, ProtonVPN is a genuinely strong recommendation.
