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.

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.
