Proton VPN

Proton VPN comes from the team behind Proton Mail, the encrypted email service born out of CERN, and it carries that lineage proudly: it is the VPN built by privacy engineers, for people who take privacy seriously. Where most VPNs ask you to trust their marketing, Proton hands you the evidence — fully open-source apps, published independent audits, and a Swiss base with some of the strongest privacy laws in the world. It is also the rare VPN with a free plan that is genuinely worth using. In this review I look at how it performs, what makes its privacy story different, what the paid and free tiers actually give you, and who should choose it.

The short version: Proton VPN is our pick for privacy and transparency, and its free plan is the best in the business. It is fast on paid plans, backed by open-source, audited apps and a Swiss jurisdiction, and layered with serious features like Secure Core multi-hop. It is not quite as effortless for streaming as ExpressVPN, and the very best speeds and unblocking need the paid tier, but if provable privacy is your priority, nothing here beats it.

Proton VPN at a glance

Speed and performance

On the paid Plus plan, Proton VPN is fast. It supports WireGuard alongside OpenVPN and IKEv2, and its own VPN Accelerator technology squeezes extra throughput out of long-distance connections by tuning how traffic is handled across its network. In practice that means nearby servers barely dent your speed, and even far-flung ones stay quick enough for 4K streaming and large downloads. Proton runs thousands of servers across 145-plus countries, including many hard-to-reach locations that reflect its mission to serve users in censored regions, so you are rarely short of a good option.

The free plan is a different story: it is deliberately limited to servers in around 10 countries and can be slower at peak times because free users share fewer servers. Crucially, though, Proton does not throttle free-plan speeds or impose a data cap — a genuinely rare and generous stance — so it remains perfectly usable for browsing and everyday privacy. If speed and unblocking matter to you, the Plus plan is the one to have; if you just want safe browsing on public Wi-Fi for free, the free tier delivers.

Security and privacy

This is Proton’s entire reason for being, and it shows. Connections use AES-256 or ChaCha20 encryption with perfect forward secrecy, a kill switch protects you if the tunnel drops, and DNS runs through Proton’s own encrypted resolvers. So far, standard. What sets Proton apart is transparency: every one of its apps — Windows, macOS, Linux, iOS and Android — is fully open-source, meaning anyone can inspect the code, and each has been independently audited. You are not asked to take the company’s word for anything.

The no-logs policy is backed by five consecutive years of independent audits, and Proton publishes the full reports for anyone to read — the 2026 assessment again confirmed that its infrastructure does not log browsing activity, DNS queries, traffic contents or identifiable connection metadata. Proton is based in Switzerland, which has strong privacy laws, no mandatory data-retention for VPNs, and sits outside the 5, 9 and 14 Eyes alliances. As a Swiss company it is also insulated from foreign gag orders. For anyone whose threat model goes beyond “hide my traffic from my ISP,” this combination of open-source code, published audits and Swiss jurisdiction is the strongest on the market.

On top of that foundation sit some serious features. Secure Core routes your traffic through hardened servers in Switzerland, Iceland or Sweden — located in a former military base and an underground data centre — before it exits, so even if an attacker is watching the exit server they cannot trace the connection back to you. NetShield blocks ads, trackers and malware at the DNS level. Tor over VPN routes you into the Tor network without the Tor browser, and the Stealth protocol disguises VPN traffic to slip past censorship. These are tools built for journalists and activists, available to everyone.

Streaming, torrenting and gaming

Streaming has historically been Proton’s weaker area, but on the paid Plus plan it now handles the major services well: Netflix libraries in various regions, Disney+, BBC iPlayer and Amazon Prime Video generally open without fuss. It is a notch behind ExpressVPN and NordVPN for sheer consistency, but it is a long way from the streaming struggles of years past. The free plan, however, is not built for streaming — expect it to be blocked by most services.

Torrenting is fully supported on Plus, with dedicated P2P servers and a strict no-logs policy that makes Proton a natural fit for privacy-conscious downloaders. Gamers get solid WireGuard speeds, though Proton’s focus is squarely on privacy rather than gaming-specific features. Split tunnelling is available on Windows and Android for routing only the apps you choose through the VPN.

The free plan: the best in the business

Most “free” VPNs are traps — they throttle you, cap your data, bombard you with ads, or quietly sell your browsing history to make money. Proton VPN’s free plan is the opposite, and it is the single best reason to start here. There is no data limit, no artificial speed throttling and no advertising; you get the same audited apps and the same no-logs privacy as paying users, just limited to servers in around 10 countries and a single device. It exists because Proton’s mission is to make privacy accessible, funded by paying subscribers. If you have ever wanted to try a VPN without risk, or you simply need safe browsing on public Wi-Fi and nothing more, Proton’s free tier is genuinely all you need — and a no-strings way to test the service before upgrading.

Plans and pricing

Proton keeps its line-up refreshingly simple: a free plan, a VPN Plus plan, and the Proton Unlimited bundle that folds VPN in with the rest of Proton’s encrypted suite. As always, longer terms cut the monthly price, and paid plans carry a 30-day money-back guarantee.

The value calculation here is unusual. If you only want a VPN, Plus is competitively priced and cheaper still on a two-year term. But if you already use, or would consider using, encrypted email, cloud storage and a password manager, Proton Unlimited is the standout deal: for roughly the price of a mid-tier VPN elsewhere you get the VPN plus Proton Mail, Drive, Pass and Calendar, all end-to-end encrypted and from the same trusted Swiss company. For privacy-minded users consolidating their tools, that bundle is hard to beat.

Apps and ease of use

Proton’s apps have matured a great deal. The Windows, macOS, Linux, iOS and Android apps are clean and approachable, with a map and list for picking locations and one-tap Quick Connect, while exposing the advanced options — Secure Core, NetShield, protocol choice, profiles — for those who want them. The Linux app is a genuine highlight, with a proper graphical interface that puts many rivals to shame, reflecting Proton’s technical, open-source audience. There is an Android TV app too, and browser extensions for quick protection. It is not quite as glossy as ExpressVPN, but it is thoughtfully designed and, being open-source, unusually trustworthy.

Open source and transparency in depth

It is worth dwelling on why open source matters for a VPN, because it is Proton’s defining advantage. When you use a VPN, you route all your internet traffic through that company’s software — you are trusting it completely. With a closed-source VPN, you have to take the privacy promises on faith. With Proton, the apps’ source code is public, so independent researchers can and do verify that the software does what it claims and hides nothing. Combine that with no-logs audits that are published in full (not just summarised in a press release), a Swiss legal home, and Proton’s track record of standing up for user privacy, and you have a service whose claims are checkable rather than merely stated. For journalists, activists and anyone with a serious threat model, that difference is the whole point.

Customer support

Support is handled through email tickets and an extensive knowledge base rather than round-the-clock live chat, which is the one area where Proton trails the big commercial VPNs. Responses are knowledgeable and the documentation is thorough, but if instant live-chat help is important to you, NordVPN and ExpressVPN have the edge.

Getting started with Proton VPN

You can start entirely for free: create a Proton account, download the app, and connect — no payment details required. To unlock the full server network, streaming and top speeds, upgrade to Plus in the app. Whichever you choose, enable the kill switch and NetShield in settings, and if you are in a restrictive network turn on the Stealth protocol. As always, run a quick check with our leak-test guide after connecting to confirm your IP and DNS are protected.

Who Proton VPN is for

Choose Proton VPN if privacy and transparency are your top priorities — it is our pick for privacy purists, journalists, activists, and anyone who wants a VPN whose claims they can actually verify. It is also the obvious starting point for anyone who wants a genuinely good free VPN, and superb value for people ready to adopt Proton’s wider encrypted ecosystem through the Unlimited bundle.

Look elsewhere if you want the most consistent streaming with zero effort (ExpressVPN), the biggest all-round feature set and 24/7 live chat (NordVPN), or the lowest price with unlimited devices (Surfshark). Compare them all on our best VPNs of 2026 list.

Is Proton VPN worth it in 2026?

If your priority is provable privacy, Proton VPN is not just worth it — it is the benchmark. No other mainstream VPN combines fully open-source apps, five years of published no-logs audits, Swiss jurisdiction and features like Secure Core, and none offers a free plan this generous. The trade-offs are real but narrow: streaming and support are a step behind the commercial leaders, and the very best experience needs the paid tier. For everyone from the merely privacy-curious — who can start free — to those with serious security needs, Proton VPN earns its recommendation, and it is the VPN I trust most when trust is the whole question.

The Proton ecosystem in depth

Proton VPN does not exist in isolation — it is one part of a wider suite of privacy tools that share the same Swiss home, the same encryption philosophy and, increasingly, the same account. Proton Mail is the encrypted email service the company started with; Proton Drive offers encrypted cloud storage; Proton Pass is a password manager; and Proton Calendar an encrypted calendar. The Proton Unlimited plan bundles all of them with the VPN. For anyone trying to move away from data-hungry big-tech services, this matters: instead of stitching together privacy tools from different companies, you get a coherent, end-to-end-encrypted set from a single organisation whose entire business model is privacy rather than advertising. The VPN is an excellent product on its own, but seen as the gateway to that ecosystem it becomes something more.

Proton VPN for censorship and high-risk users

Proton was built with a specific hard case in mind: users in censored or hostile environments, where a VPN failing is not an inconvenience but a risk. That heritage shows in features ordinary VPNs treat as afterthoughts. The Stealth protocol disguises VPN traffic to slip past sophisticated blocking; Secure Core routes connections through hardened servers in privacy-friendly countries so a compromised exit node cannot unmask you; and Tor over VPN adds the anonymity of the Tor network in a click. Proton has also repeatedly added free servers in newly restrictive countries specifically to help people there get online safely. If your reason for wanting a VPN is serious — journalism, activism, or simply living somewhere the internet is not free — Proton is built for you in a way most consumer VPNs are not.

How Proton VPN compares

Among the big names, Proton occupies a distinct position. NordVPN and ExpressVPN are more polished for streaming and offer round-the-clock live chat, but neither is open-source and neither has a free plan worth using. Surfshark is cheaper with unlimited devices, but it is closed-source and based in a 9 Eyes country. Proton’s trump cards — fully open-source audited apps, five years of published no-logs audits, Swiss jurisdiction, Secure Core and a genuinely generous free tier — are exactly the things privacy-focused users weigh most heavily. If your decision comes down to which VPN you can trust with the least blind faith, Proton wins that argument more convincingly than anyone.

The verdict

Proton VPN is the privacy specialist that also happens to be a strong all-rounder on its paid plan. Its open-source, audited apps and Swiss base give it a trust story no rival can match, Secure Core and Stealth make it genuinely capable in hostile network conditions, and its free plan is the most generous and honest in the industry. It gives up a little on streaming polish and live-chat support, but those are small prices for what you gain.

If you want a VPN you can verify rather than simply trust — or the best free VPN to start with — Proton VPN is the one to choose, and it comfortably earns its place among the best VPNs of 2026.
