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.

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.

Read our full ProtonVPN review for deeper speed benchmarks and streaming test data.

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.
