Overview

Proton VPN is a commercial service operated by Proton AG in Switzerland, offering a genuinely useful free tier with unlimited data and open-source apps. It’s one of the few providers with independent audits and transparent infrastructure decisions, like its shift to Quad9 for encrypted DNS in 2026. However, its privacy claims are tied to payment identity, and Swiss jurisdiction isn’t immune to legal pressure, as shown by past incidents.

Logging & privacy

Proton VPN claims a strict no-logs policy under Swiss law, retaining only an overwritten timestamp of the last successful login - no IP addresses or connection logs. This claim is backed by audit evidence: Securitum audited its apps and infrastructure in 2023 and 2024. However, the 2021 case where Proton Mail logged a French activist’s IP shows that legal orders can extract data when accounts are tied to real identities. There is no warrant canary, and while the audits are meaningful, the Secure Core servers remain a black box.

Pricing & the renewal trap

The intro price is $3.49/month, billed as $83.76 for the first 24 months. After that, it renews at $6.99/month, billed annually as $83.88 - exactly double the introductory rate. The renewal ratio is 2x, meaning you pay significantly more after the first term. A 30-day refund window applies, and the total cash outlay over three years is $167.64. While the free tier requires no payment, paid plans support crypto (BTC, XMR) and allow email-only signup with no KYC.

Features & performance

Proton supports WireGuard, OpenVPN, IKEv2, and its proprietary Stealth protocol for evading censorship. Features include a kill switch, split tunneling, multihop, Tor over VPN, and P2P on all servers. It offers dedicated IPs and works with streaming platforms, though user reports on Reddit and Hacker News note increasing detection issues. The app is open-source, but we have not conducted independent performance tests. Server count is unspecified, but coverage spans 140 countries.

Ownership & track record

Proton AG, based in Geneva, Switzerland, operates the service. While independent and not part of a larger conglomerate, it has faced legal pressures: in 2021, Swiss authorities compelled Proton Mail to log an activist’s IP, and in 2026, a Spanish court ordered Proton to block LaLiga piracy domains - a move the company contested, saying it wasn’t notified. Community feedback highlights support quality concerns and growing detection of Proton’s IPs on streaming sites, suggesting infrastructure challenges.

Censorship resistance

Proton VPN offers Stealth mode, which wraps traffic in TLS to mimic HTTPS and bypass deep packet inspection, and “alternative routing” when direct access is blocked. It also announced ProTUN, a Rust-based WireGuard framework, in September 2026 to improve resilience. These tools make it viable for use in censored environments like China or Iran, though success depends on ongoing cat-and-mouse dynamics with censors. Users in Spain have reported blocks due to court orders, showing legal threats can undermine technical resistance.

Verdict

Proton VPN is a trustworthy choice if you value open-source transparency, real audits, and a no-logs policy with third-party verification. It’s ideal for users who want a capable free tier and censorship evasion tools. But be aware: the renewal price doubles, detection on streaming platforms is rising, and the company has complied with legal orders in the past. Proton pays affiliate commissions via PartnerStack, so many reviews are financially biased - this one isn’t.
