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.
