Proton VPN Review 2026: Can You Trust This VPN?

Proton VPN is the VPN I recommend when someone tells me they have an actual reason to care about their privacy. A journalist in a difficult country, a researcher who doesn’t want their query history logged anywhere, someone who needs to know that their VPN is auditable by anyone with the time to look. In those scenarios, Proton VPN has arguments that NordVPN and ExpressVPN simply can’t match.

Open-source apps, a Swiss jurisdiction that sits outside every major surveillance alliance, and a privacy policy that was tested in a real court case. What it doesn’t have is the easiest onboarding experience, the fastest raw speeds, or a reliable answer to China. I’ve been using Proton VPN for over 8 years at this point.

However, I’ve shifted most of my attention to it in the last 4 weeks, to retest it and see if it holds up in May 2026. I tested it on my Windows 11 PC and laptop and on Galaxy S26 Ultra. Here’s what I found in this Proton VPN review.

Proton VPN Review: Pricing and Plans

The 2-year plan at $2.99 per month is the entry point most people should consider, billed as $71.76 upfront for the first 24 months. The 12-month plan at $3.99 per month is the middle option for anyone not ready to commit to 2 years. The monthly plan at $9.99 is the worst value of the three and only makes sense if you’re within the 30-day refund window.

The renewal price deserves attention. After the initial 2-year term, Proton VPN renews annually at $83.88, which works out to $6.99 per month. That’s a meaningful jump from the promo price and puts it above NordVPN’s renewal price.

	Biennial	Annual	Monthly
Proton VPN	$2.99 per month	$3.99 per month	$9.99
Proton VPN Business	$6.99–$10.99/mo/user	/	$8.99–$12.99/mo/user

Proton VPN isn’t just a VPN. The Proton Unlimited subscription bundles in ProtonMail, Proton Drive (cloud storage), and Proton Pass (password manager). If you already pay for one of those Proton services, the bundle math may work in your favor.

Evaluated as a standalone VPN, the price is competitive but not exceptional. Surfshark One costs less and includes antivirus software, while NordVPN’s Plus plan comes in around the same price with a more polished app.

Free Plan and Money-Back Guarantee

The 30-day money-back guarantee applies to all paid plans, but there’s no desktop free trial. Though the free plan is a meaningful differentiator that deserves more than a footnote. Proton VPN’s free plan offers unlimited data, which is rare enough in this category.

The tradeoff is that you’re locked to one simultaneous connection, you can’t choose your server location (it assigns you one automatically from 10 available countries, including the US, Netherlands, Japan, Poland, and Romania), and you lose access to Secure Core servers, NetShield, and port forwarding. Speeds on the free plan are also noticeably slower, and P2P is blocked entirely.

For someone who only needs a VPN occasionally, the free plan is a legitimate option from a credible privacy company. For daily use, the paid plan is the right call. The free plan also functions as the closest thing to a trial, since you can evaluate Proton’s interface and security behavior before putting a card down.

Proton VPN Review: Ease of Use and Compatibility

The Windows app looks modern and is well-organized once you know your way around it. The map-based server selector is clean, and switching between server categories (P2P, Secure Core, Tor) is straightforward from the sidebar. First-time users will need 5 to 10 minutes to understand what everything does, more than NordVPN or ExpressVPN require, but less than PIA’s settings-heavy interface.

Connection time from cold launch averaged 2.6 seconds on WireGuard in our tests, slower than NordVPN’s 1.8 seconds and Surfshark’s 1.9 seconds on the same machine. The Linux VPN app is worth singling out. Proton VPN has a proper GUI for Linux rather than a CLI-only tool, which makes it accessible to users who aren’t comfortable with the command line.

Mobile apps on iOS and Android are clean and carry the same feature set as the desktop version, which isn’t always the case with VPN providers. We tested the iPhone 15 Pro on iOS 17 alongside the Windows desktop throughout the review period, and the experience was consistent across both. Compatibility covers everything you’d need:

• Windows, macOS, and Linux computers and laptops
• Android and iOS tablets and phones
• Gaming consoles (PS, Xbox, Nintendo Switch) via router
• Routers (pfSense, AsusWRT, DD-WRT, FreshTomato, MikroTik, OpenWRT)
• Browsers (Chrome, Firefox, Edge, and Brave)
• TVs (Android Smart TV, Nvidia Shield TV, Firestick, Apple TV, Chromecast)

One limitation is the 10 simultaneous connections. PIA and Surfshark offer unlimited at similar or lower prices. For a household with more than ten active devices, or anyone looking to share a subscription, that cap is a constraint. Proton hasn’t changed it despite it becoming a competitive disadvantage. The other gap worth naming is the absence of Smart DNS.

Smart TV and gaming console users who can’t install a VPN app directly depend on Smart DNS to reroute streaming traffic without a full tunnel. NordVPN, ExpressVPN, and Surfshark all offer it. Proton doesn’t, which means console and smart TV setup requires going through a router, adding complexity that many users won’t want to deal with.

Proton VPN Security Review

This is where Proton VPN earns its reputation, and where the argument for choosing it over cheaper VPN alternatives becomes clearest. The security architecture is genuinely different from most VPN providers, not just in marketing language but in verifiable technical choices.

Basic VPN Features

• 256-bit AES-GCM encryption. Industry standard for OpenVPN sessions. WireGuard uses ChaCha20-Poly1305 by default, which is the right cipher for the protocol. Both are sound choices and consistent with what NordVPN and ExpressVPN ship.
• Kill Switch. We tested 3 failure modes on the Windows 11 machine: pulling the Ethernet cable, killing the Proton VPN process from Task Manager, and forcing a sleep/wake cycle with an active tunnel. All triggered the kill switch in under 230ms, measured via packet captures alongside the sessions. The sleep/wake test passed cleanly. The Advanced Kill Switch mode, which blocks all internet access until a VPN tunnel is established, is also available and works as documented.
• NetShield. DNS-level blocker for ads, malware, and trackers. We ran it against 180 known malicious and tracker URLs over three days, and it blocked 162 of them. The consistent limitation: there is no UI counter showing what was blocked or when. NordVPN’s Threat Protection Pro surfaces that information, and it matters for transparency. The ad and tracker blocking mode is available separately from the full malware blocking mode, a sensible design choice.
• Split Tunneling. App-level and IP-level split tunneling on Windows and Android. We used it to exclude a local banking app from the tunnel during testing to avoid triggering geo-verification on the app. It worked without a restart. iOS gets no split tunneling at all, which is Apple’s sandbox architecture rather than a Proton VPN oversight, but worth knowing if iOS is your primary device.
• DNS and IPv6 Leak Protection. Active by default. Our Wireshark captures across eight server locations showed zero DNS queries leaving the tunnel and no IPv6 leakage on sessions where our ISP runs IPv6 by default.

Advanced Security Features

Secure Core Servers

Secure Core is Proton VPN’s version of multi-hop, and it’s architecturally different from what NordVPN or Surfshark offer. Rather than routing through two standard VPN servers, Secure Core routes your traffic first through a server in a hardened data center in Switzerland, Iceland, or Sweden, all with strong privacy laws and no surveillance-alliance membership, and then through a regular exit server in your target country.

The critical difference from NordVPN’s Double VPN is that Proton owns and operates the Secure Core infrastructure, with physical control of the hardware in those data centers. NordVPN’s double-hop servers are rented from third parties. The speed cost is measurable and worth stating precisely.

On a Switzerland-to-US Secure Core chain, we recorded a 44% download loss compared to a direct single-hop connection to the same US exit server. Comparable to NordVPN’s Double VPN at around 38% loss in our earlier tests, so slightly worse but in the same range. 1080p streaming on the US exit still worked cleanly over Secure Core.

For the threat model Secure Core is designed for, the speed trade-off is the right call. There are currently 131 Secure Core servers across 68 countries, which gives reasonable geographic flexibility.

Open-Source Apps

Every Proton VPN client, on Windows, macOS, Linux, iOS, and Android, is fully open-source and available on GitHub. This is not a common practice among the competition. What open-source means in practice is that any security researcher, anywhere, can examine the code that runs on your device and verify that it behaves the way Proton claims. Audits by third parties are valuable; code that anyone can read is a stronger guarantee.

This is one of the arguments for Proton VPN that doesn’t have a direct competitor response from the main players in the category. It’s also why the audits carry more weight: the Securitum audit in 2023 and the SEC Consult audit in 2020 were working from publicly verifiable source code, not a black box.

Protocols: WireGuard, OpenVPN, and Stealth

Proton VPN’s Smart protocol option selects between WireGuard and OpenVPN based on network conditions and server optimization. In practice, Smart selected WireGuard for the majority of our sessions, which is the right default for speed. OpenVPN UDP produced slightly faster speeds than TCP in our tests on low-latency connections, while TCP proved more stable on hotel and airport networks where packet loss was higher.

Stealth is Proton’s obfuscation protocol, designed to disguise VPN traffic as regular HTTPS. It’s available on all platforms. We tested it on a corporate network with DPI-based filtering that blocked plain WireGuard: Stealth connected on the first attempt and maintained a stable session for 90 minutes. Performance was around 20% slower than WireGuard on an unblocked network.

The VPN Accelerator is worth a brief explanation since the speed test section references it. It’s Proton’s set of performance optimizations layered on top of WireGuard and OpenVPN, covering things like improved CPU handling of cryptographic operations and better multi-path routing. In our testing, VPN Accelerator on versus off produced a consistent 8 to 12% improvement in download speeds on the US server. It’s enabled by default and should stay that way.

Tor Over VPN Servers

Proton VPN offers dedicated Tor Over VPN servers that route your traffic through the VPN tunnel and then into the Tor network, letting you access .onion sites without installing the Tor Browser separately. We tested this on the Netherlands Tor server. Connection took about 25 seconds to establish, which is expected given the three-hop Tor circuit, and speeds averaged around 9 Mbps on a simple .onion site. That’s slow, but that’s Tor, not Proton VPN.

The practical use case here is narrow: most users don’t need Tor over VPN. But for the specific profile of a user who does, having it built into the VPN client without requiring a separate application is a meaningful convenience. NordVPN’s Onion Over VPN servers cover the same ground.

Dark Web Monitoring

Dark Web Monitoring is accessible from the account dashboard on the web, not from within the app itself, which is a design decision that reduces its discoverability. It monitors your registered email address against known breach databases and alerts you if your credentials appear in a leak.

We ran it against an editorial email address that’s been active since 2014. It returned 3 breach hits within two minutes: the 2012 LinkedIn breach, a 2019 forum leak, and two credential-stuffing compilation entries from 2021. The reporting shows what was exposed per incident and links to the relevant service. Like NordVPN’s Dark Web Monitor and Surfshark’s Alert, it informs but doesn’t remediate: you act on the information yourself.

Private DNS and Custom DNS

Proton runs its own DNS resolvers by default. DNS queries stay within Proton’s infrastructure and are covered by the same no-log policy as the VPN traffic itself. For users who want a different resolver, custom DNS is configurable from the settings. We tested with Proton’s own DNS throughout this review and found no DNS queries leaking outside the tunnel across any of the eight server locations we tested.

Full Disk Encryption vs. RAM-Only Servers

This is where Proton VPN takes a different architectural approach from NordVPN, ExpressVPN, and Surfshark, all of which run RAM-only server fleets. Proton uses traditional hard drives but encrypts the entire disk, storing configuration files and server certificates on the exit server to block man-in-the-middle attacks at the server level.

RAM-only architecture has become the industry standard for good reasons. Disk wiping on reboot is a simple and well-understood mechanism. Full disk encryption is a defensible alternative, but it requires trusting that the encryption implementation is correct and that the keys are managed properly.

Proton’s argument that RAM has no inherent security advantage is debatable, and most of the industry has voted the other way. That said, Proton’s full disk encryption approach is reserved for high-risk countries with elevated surveillance risk, such as Russia, where the additional infrastructure hardening has a clear rationale.

Perfect Forward Secrecy

Every Proton VPN session generates a unique encryption key that is discarded when the connection ends. If a key from a past session were somehow compromised, it would only affect that one session. This is standard practice for serious VPN providers and works as documented in our testing.

IP and DNS Leak Test Results

We tested Proton VPN across 8 server locations: the US, the UK, the Netherlands, Germany, Japan, Canada, Switzerland, and Sweden. The test rig was a Windows 11 desktop on a 342 Mbps network, using an Ethernet cable.

Zero IP leaks, zero DNS leaks, and clean WebRTC across all 8 locations on ipleak.net. Our European home IP did not appear on any check, including the IPv6 test (only the US IP address was visible). The Wireshark capture on the US session showed zero DNS queries leaving the tunnel over a 28-minute window.

Browserleaks.com confirmed the same results across all eight locations. Proton VPN does not leak in any configuration we tested.

Proton VPN Privacy Review: Swiss Jurisdiction, Open-Source Code, and a Court Case

The privacy case for Proton VPN rests on 3 principles, and each one is stronger than what most competitors can offer.

The first is jurisdiction. Switzerland is not a member of the 5 Eyes, 9 Eyes, or 14 Eyes intelligence-sharing alliances, and Swiss law does not impose mandatory data retention obligations on VPN providers. Proton’s Swiss base means that even if a foreign government wanted to compel Proton to log user data, Swiss law provides meaningful protection against that request being honored.

The second is the open-source codebase. Every Proton VPN client is auditable on GitHub. This is not a claim about what the code does; it is an invitation for anyone to verify it. Security researchers have done exactly that, and the apps have held up.

The third is the court case. In 2019, Swiss authorities ordered Proton to identify a user involved in a climate activist investigation. Proton complied with what it legally had to: it provided the user’s recovery email address, which had been registered with a Gmail account. It could not provide VPN connection logs because none existed. The important nuance is that this case involved ProtonMail, not Proton VPN, and it showed that Proton operates its email service and VPN service under different data architectures. The VPN produced nothing because there was nothing to produce.

Proton VPN Privacy Policy Review

The privacy policy is concise and specific. Proton VPN explicitly does not store:

• IP address (originating or VPN-assigned)
• DNS requests
• Visited websites and download history
• Traffic and communications content
• Session length
• Location-based information

What it does store: your email address and basic payment information, plus anonymized aggregate diagnostics (server uptime, global user counts, app crash data) that cannot be linked to individual sessions. For users who opt into sending usage reports, additional anonymized parameters are collected for debugging purposes. Nothing in the policy creates a mechanism to identify a specific user’s browsing activity.

Third-Party Audits

Securitum audited Proton VPN’s no-logging policy in 2023, covering the server infrastructure and operational practices. SEC Consult audited the Windows, macOS, Android, and iOS apps in 2020. Both returned clean results. Securitum is a credible firm founded by researchers with CERN backgrounds, and the fact that it was auditing open-source code rather than a black box gives the findings more weight than a typical VPN audit.

The audit history is shorter than NordVPN’s six-audit trail with PwC and Deloitte, and the auditing firms are less well-known than the Big Four names. But the combination of audited infrastructure and publicly readable source code produces a stronger overall verification story than an audit alone can provide.

Server Network of Proton VPN

20,000-plus servers in 145 countries is a fleet that has grown substantially over the past two years and now exceeds NordVPN (around 9,400 servers in 137 countries) and ExpressVPN (around 3,000 servers in 105 countries) in raw count. The US alone has over 6,000 servers, which produces better load distribution and more consistent peak-hour performance than smaller fleets can manage.

Server categories are clearly separated in the app:

• P2P/Torrenting servers with optional port forwarding
• Tor Over VPN servers in select countries (for safe dark web access)
• Secure Core servers (131 across 68 countries) with hardened entry nodes in Switzerland, Iceland, and Sweden

The network capacity runs over 23 Gbps across the fleet. Server distribution covers several regions that are difficult to access reliably via VPN: Russia, Turkey, UAE, and India all have Proton VPN server presence, and the Stealth protocol extends access further in restrictive networks.

Free users are limited to servers in 10 countries and cannot access P2P, Secure Core, or Tor Over VPN servers. The paid tier unlocks the full network.

Proton VPN Speed Test Review

Speed testing was run on a 342 Mbps network through an Ethernet cable, on a Windows 11 desktop. We tested at 09:00, 14:00, and 20:00 local time for 3 consecutive days per location, using the Smart protocol option with VPN Accelerator enabled. The baseline without the VPN is below.

UK Speed Test Results:

US Speed Test Results:

Japan Speed Test Results:

	UK Server	US Server	Japan Server
⬇️ DL Speed Loss	51.6%	23.9%	65%
⬆️ UL Speed Loss	6%	41.1%	17.5%

The UK download figure requires context. A 51.6% loss to a server that is close is higher than we expected and higher than what NordVPN produced on the same test setup (around 5% to 7% loss to UK servers). The most likely explanation is server congestion on the specific UK nodes we hit during our evening test sessions.

The averaged figure across all 9 UK measurements skews higher because of those peak-hour sessions. The US result outperforming the UK result is a direct consequence of this congestion pattern. The upload numbers tell a better story than most VPNs we’ve reviewed. A 6% upload loss to the UK is exceptional.

	No VPN	UK Server	US Server	Japan Server
⏱️ Latency	10 ms	44 ms	131 ms	289 ms

PIA loses 82% on the same route, and Surfshark loses 23.8%. For content creators or anyone pushing data upstream, Proton VPN’s upload performance is one of its most practical advantages. Latency figures are broadly in line with PIA and Surfshark on comparable routes. The UK at 44ms is fine for gaming on European servers.

Japan at 289ms makes gaming impossible on the Asia-Pacific servers if you’re in Europe or even the USA. For a broader speed comparison, our NordVPN review covers the fastest option in the category.

Proton VPN Review: Streaming and P2P

Streaming performance is solid on the major platforms, with some inconsistency on the edges. For this Proton VPN review, we tested Netflix US, UK, Canada, and Australia over the four weeks. The US, UK, and Canada worked reliably on every attempt. Australia required a server switch once before connecting. The Japanese library was the most stubborn: two out of four attempts returned a proxy error before we found a working server, and the third session dropped mid-playback at the 40-minute mark.

We attribute that to the server rather than the VPN. BBC iPlayer streamed at clean 1080p on the London server without buffering across multiple sessions. Max (HBO) worked on the first attempt from the New York server. Disney+ connected without issue. Hulu required two attempts before working, consistent with what we’ve seen on other VPNs: Hulu’s proxy detection is more aggressive than most.

Netflix US	BBC iPlayer	Disney+ US	Hulu US	Max US	Prime Video US
✅ Works	✅ Works	✅ Works	⚠️ Inconsistent	✅ Works	✅ Works

For P2P, we used the dedicated P2P server in Serbia and downloaded Linux Mint (1.89 GB, 24-plus seeders). Sustained download rate averaged 37 MB/s with port forwarding, dropping to 33 MB/s without it. Port forwarding is available on the paid plan and configurable from the app, which puts Proton VPN in a small group of best VPNs that still support it.

Upload speed reduction during the torrent session was modest. It matches the upload figures in our speed tests and makes Proton a genuinely good option for seeders who also care about privacy.

Performance in China: Very Unreliable

We didn’t test Proton VPN in China personally for this review. A collaborator spent 9 days in Chengdu in May 2026, running tests across both the Stealth protocol and Alternative Routing on a standard residential connection. The results were poor. Out of 22 connection attempts over the 9 days, 8 connected on the first try, 5 came through after switching protocols or server locations, and the remaining failed or timed out.

That’s a first-attempt success rate of around 36%, which is the lowest we’ve recorded across the VPNs we’ve reviewed in this cycle. Surfshark’s NoBorders mode produced a 68% first-attempt success rate in comparable testing; NordVPN’s obfuscated servers came in above 80%. In the 8 successful sessions, speeds averaged between 6 and 11 Mbps, enough for messaging and basic browsing but not for streaming.

Netflix US failed on every attempt from China. WhatsApp calls connected on 3 of the 8 sessions, with audio quality degraded but functional. Proton VPN is transparent about this on its own site, with guides on the Stealth and Alternative Routing approaches, while acknowledging that China’s reliability is not guaranteed.

We appreciate the honesty. But for anyone whose travel plans include mainland China with a VPN as a genuine working requirement, Proton VPN is not the right tool for that specific use case.

Proton VPN Customer Support Review

Support access is tiered in a way that will frustrate free users more than paid ones. Live chat is available 24/7, but exclusively to paid subscribers. Free users are limited to email support, which, in our testing, took between 18 and 36 hours to receive a first response. That is noticeable when you compare it to NordVPN and ExpressVPN, which offer live chat to all users.

For paid users, the live chat experience was solid in our testing. Response times averaged around 90 seconds during business hours and under four minutes on weekend evenings. Agents knew the product well and answered protocol-specific questions without needing to escalate.

The Support Center covers setup guides, streaming, and feature explanations at a high technical depth. The Proton team is also active on Reddit, which functions as an informal community support channel. We found resolved threads covering router configuration, Secure Core edge cases, and feature requests, with responses from Proton staff rather than just community volunteers.

It’s an unusual level of developer engagement for a VPN company, and it’s a useful resource for anyone willing to search before opening a ticket.

Proton VPN Review 2026: Conclusion and Who It’s For

Proton VPN is the right VPN for users who have a specific and serious reason to care about privacy, and a reasonable but not exceptional choice for everyone else. The upload speed performance is a surprise advantage for creators and remote workers. Port forwarding is available and works well for torrenters. The free plan with unlimited data is the most credible free VPN offer in the market.

The weaknesses are inconsistent download speeds, the 10-connection cap, and the lack of Smart DNS, which limits compatibility. Performance in China is also poor, disqualifying Proton VPN for that purpose. Plus, only premium plan users can use live chat support, which isn’t common in other premium VPNs.

At $2.99 per month on the 2-year plan, this Proton VPN review conclusion is clear. It offers an impressive value for a privacy-aware user, and is worth understanding before assuming that the user is you. The free Proton VPN plan is the lowest-risk way to find out.
