ProtonVPN Review

Secure and Free VPN Service from the Creators of ProtonMail

ProtonVPN is the obvious pick for privacy-first users, open-source advocates, and anyone who wants a genuinely usable free tier that doesn't monetise via tracking. It's built and run by the team behind Proton Mail and shares the same Swiss privacy framing — which, in this category, still counts for something.

Switzerland sits outside the 5, 9, and 14 Eyes intelligence-sharing alliances and has strong constitutional privacy protections, which gives the no-logs policy a credible legal foundation. Securitum completed Proton VPN's fourth consecutive annual no-logs audit in August and September 2025, including on-site work in Zürich, server inspection, and confirmation that there is no deep packet inspection on production servers.

Every client app — Windows, macOS, Linux, iOS, Android — is open source on GitHub and has been independently audited by SEC Consult, with newer reviews from researcher Ruben Santamarta. This level of transparency is rare among major VPNs. The free tier deserves its reputation.

There's no data cap, no ads, and no speed throttling, and the same no-logs policy applies as on paid plans. That alone separates ProtonVPN from the vast majority of free VPNs, which fund themselves through tracking or data sale. On the paid side, Secure Core multi-hop routes traffic through hardened bare-metal servers in Switzerland, Iceland, or Sweden before exiting — which materially reduces de-anonymisation risk from a single compromised exit node.

Streaming on the paid plan is reliable: Netflix across 20-plus libraries, Disney+, HBO Max, Amazon Prime Video, and BBC iPlayer all unblock consistently in recent reviews. The constraints are worth noting. The free tier is intentionally limited — only 5 server countries, 1 device, no P2P, no streaming, and you can't pick a specific server.

Independent benchmarks consistently rank WireGuard speeds 20 to 30 percent behind NordVPN's NordLynx on like-for-like routes, with Surfshark 5 to 10 percent ahead in head-to-head download tests. Secure Core, NetShield ad-blocking, Tor over VPN, P2P, and access to the 10 Gbps server pool are all paid-only, so the free-forever pitch leans heavily on the premium tier.

The 30-day money-back guarantee is prorated to the unused portion rather than a full refund, and the cancel button alone doesn't trigger it — users must contact support manually. Live chat is also gated to paid subscribers and runs roughly 09:00 to midnight Central European Time, so weekend users outside Europe largely rely on ticketed email support.

Pick ProtonVPN if open-source clients, Swiss jurisdiction, and a usable free tier matter most. If raw speed or unlimited devices are the priority, NordVPN or Surfshark will serve you better.
