Most VPN companies tell you to trust them. Proton VPN shows you the code, publishes the audit results, operates under Swiss law, and lets you decide. The team that built Proton Mail applied the same philosophy to a VPN: assume the threat is real, build accordingly, prove it publicly.
Specs
Protocol: WireGuard, OpenVPN, IKEv2, Stealth. Connections: up to 10 on paid plans, 1 on free (Proton's own published figures, checked 29 July 2026). Audit: Proton publishes its no-logs audits in full — Securitum has carried out five consecutive annual independent audits, the most recent in 2026 — alongside earlier app audits by SEC Consult. Kill switch: permanent + standard modes. Ad blocking: NetShield (DNS-level). Free tier: yes — no data cap and no speed limit, ten server countries, one device, with the server assigned rather than chosen. Servers: Proton advertises a large global network, but its own published country count differs between pages (110+ on the free-plan comparison page, a higher figure in its support documentation as of July 2026), so we do not print a single number here — check protonvpn.com for the current count. Price: Proton runs several term lengths and regional pricing, so we quote no monthly figure; open Proton's own pricing page to see what it quotes you.
Why Switzerland Matters
Switzerland is not a member of the EU, Five Eyes, Nine Eyes, or Fourteen Eyes. Swiss law actively prohibits bulk surveillance. A US government subpoena has no direct legal effect on a Swiss company. An EU data retention directive doesn't apply. This is structural privacy, not just marketing.
Open Source and the Audit Standard
ProtonVPN's apps are fully open source — every line of code is publicly available on GitHub. Audit reports are published in full, including found issues and resolutions. Not summarised. Not behind an NDA. This is the standard Mullvad also meets and that most other VPN providers fall short of.
Stealth Protocol
Disguises VPN traffic as regular HTTPS traffic so that networks which detect and block standard WireGuard or OpenVPN connections cannot easily tell a VPN is in use. This makes Stealth the protocol to reach for on corporate networks, in restrictive countries, or against aggressive ISP filtering, where ordinary VPN protocols are the first thing to be blocked.
The Free Tier
Proton advertises the free plan as having no data or speed limits — genuinely unlimited bandwidth, which almost no other free VPN offers (verified against protonvpn.com/free-vpn, 29 July 2026). Servers in ten countries — the Netherlands, Japan, Romania, Poland, Norway, Switzerland, Singapore, Mexico, Canada and the US. No ads. Same no-logs policy as paid plans. One device at a time. The limitation that matters most is not the country count but the lack of choice: on the free plan you cannot pick which of the ten you land in. Proton connects you to the fastest free server for your location and picks the next one at random, behind a cooldown that starts at 45 seconds and then rises to 10-minute intervals (protonvpn.com/support/change-server-free-plan, checked 29 July 2026). Free users also get lower priority at peak times, and Proton lists streaming and P2P as paid-only features. For basic protection at zero cost this is still the most honest free VPN available — but treat ten countries as coverage, not as a country picker. For a side-by-side look at whether that free tier is enough for you, or where you should move to a paid plan or alternative, see our dedicated breakdown, is Proton VPN's free tier enough?.
Pros and Cons
Pros: fully open source apps; fully public audit reports, most recently the 2026 Securitum no-logs audit; Swiss jurisdiction — outside all major surveillance alliances; Stealth protocol for restrictive networks; the most honest free tier available, with no data cap. Cons: streaming is less consistent than ExpressVPN or NordVPN, and Proton restricts streaming and P2P to paid plans; the free tier assigns your server rather than letting you choose. On speed we make no measured claim of our own — we did not run a first-hand benchmark for this edition, and Proton ships a modern WireGuard-class protocol, which is what matters most on current hardware.
The Verdict
Proton VPN is the right choice if you genuinely care about privacy rather than just assuming it. The open source apps, fully published audits, and Swiss jurisdiction put it at the top of the privacy-first tier, and the free plan is the most credible free VPN available. If your priority is instead the most consistent streaming and the broadest everyday feature set, NordVPN — which this review names in its own cons — is the honest alternative to weigh against it, and our roundup of the best VPNs of 2026 puts the full field side by side. This is privacy and security information, not financial advice; pick on your own threat model rather than on a single verdict.
Frequently Asked Questions
Is Proton VPN Free actually free?
Yes. Proton advertises the free plan as unlimited and free forever, with no data or speed limits and no ads, under the same no-logs policy as paid. The limits are one device at a time, ten server countries, no streaming or P2P support — and Proton assigns the server rather than letting you choose it.
Is Proton VPN open source?
Yes — all Proton VPN apps are fully open source on GitHub, and Proton publishes its independent no-logs audit reports in full, most recently the 2026 Securitum audit.
Does Proton VPN work for streaming?
On paid plans, yes, though less consistently than ExpressVPN or NordVPN. Proton lists streaming support as a paid feature, so the free tier does not support it.
