Proton VPN Review: Swiss Privacy Pedigree Meets a Serious Server Network

Most VPNs are privacy products built by marketing companies. Proton VPN is the opposite: a privacy company — born at CERN, maker of Proton Mail — that built a VPN. That heritage shapes everything about it, from jurisdiction to source code. Here's our full review.

The Proton ecosystem and Swiss jurisdiction

Proton operates under Swiss law, among the strictest privacy regimes anywhere: no mandatory data retention for VPNs, no membership in the 5/9/14-Eyes intelligence alliances, and legal process that runs through Swiss courts. Combined with the Proton ecosystem (Mail, Calendar, Drive, Pass), one account can cover your whole private-by-default stack.

Pricing — and the free tier

€2.49/month long-term is competitive for what you get. Uniquely in our ranking, Proton also runs a reputable free tier — no ads, no data selling, no logs, just fewer locations and one device. It's the only free VPN we'd actually recommend, and a zero-risk way to test the apps before paying. Paid plans carry a 30-day money-back guarantee.

Server network: 20,000+ servers, 148 countries

The network has grown dramatically — 20,332 servers across 148 countries puts Proton second only to PIA in fleet size among our picks, with country coverage rivalling NordVPN's. Secure Core routes your connection through hardened servers in Switzerland, Iceland or Sweden (literally in a former military bunker, in one case) before exiting elsewhere — protecting against compromised exit servers at some speed cost.

Privacy architecture: open source, audits, no-logs

Every Proton VPN app is fully open source and independently audited, with reports published. The no-logs policy has been verified in practice: Swiss legal requests have come back empty, as there was nothing to hand over. If "trust, but verify" is your standard, no service in this ranking verifies harder.

Stealth protocol: VPN detection evasion

Proton's Stealth protocol disguises VPN traffic as ordinary HTTPS, helping it work on networks that actively block VPNs — restrictive corporate Wi-Fi, certain countries, some streaming services' detection layers. In our tests, Stealth connected where standard WireGuard connections were refused.

Speed tests

WireGuard on a 500 Mbps line:

• Nearby (Zurich): ~420 Mbps down, ping 15 ms
• US East: ~270 Mbps down, ping 99 ms
• Via Secure Core: roughly 30–40% slower — the privacy tax, only when you opt in

VPN Accelerator (on by default) noticeably improved long-distance throughput in our testing.

Streaming and P2P

Netflix US and Disney+ worked on Plus-plan servers in our tests. P2P is supported on designated servers with port forwarding available. Streaming reliability has improved markedly but still trails ExpressVPN — expect an occasional server hop.

Apps and devices

Windows, macOS, Linux (full GUI), Android, iOS, Android TV and Apple TV, 10 simultaneous connections. The honest gap: smart-TV and router coverage is narrower than rivals, and some advanced features land on Windows/Android first.

Pros and cons

Pros: Swiss jurisdiction, open-source audited apps · proven empty-handed legal responses · Stealth anti-detection protocol · Secure Core architecture · genuinely trustworthy free tier · 15,000+ servers

Cons: streaming less bulletproof than ExpressVPN · Secure Core costs speed · narrower platform extras · monthly price is mediocre value

Verdict: the privacy purist's pick

If your threat model is real — journalism, activism, or simply a hard requirement that your VPN provably keeps nothing — Proton VPN is the most verifiable choice in our ranking, and the free tier means you can adopt it gradually. Pure streamers will be happier with ExpressVPN; privacy-first users won't find better.
