ProtonVPN Review

ProtonVPN is a Swiss VPN from the Proton Mail team with open-source apps and a free tier that has no data cap or ads. It suits privacy-first users.

ProtonVPN is the obvious pick for privacy-first users and open-source advocates. It also suits anyone who wants a usable free tier that doesn't make its money from tracking. It's built and run by the team behind Proton Mail under the same Swiss privacy protections, which still count for something among VPNs.

Switzerland is outside the 5, 9 and 14 Eyes intelligence-sharing alliances and has strong constitutional privacy protections. That 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.

The audit included on-site work in Zürich and server inspection. It confirmed there is no deep packet inspection on production servers. Every client app (Windows, macOS, Linux, iOS and Android) is open source on GitHub and has been independently audited by SEC Consult.

Researcher Ruben Santamarta has done newer reviews. This level of transparency is rare among major VPNs. The free tier deserves its reputation.

It has no data cap, no ads and no speed throttling. 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 selling data.

On paid plans, Secure Core multi-hop routes traffic through hardened bare-metal servers in Switzerland, Iceland or Sweden before it exits. That considerably reduces the risk of de-anonymization 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 free tier is limited on purpose. It offers only 5 server countries and 1 device, with no P2P or streaming.

You also can't pick a specific server. Independent benchmarks consistently put WireGuard speeds 20 to 30 percent behind NordVPN's NordLynx on like-for-like routes. Surfshark comes out 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. The cancel button alone doesn't trigger it: users must contact support manually.

Live chat is also limited 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.
