Overview

Proton VPN is a commercial service based in Switzerland, operated by Proton AG. It offers a genuinely usable free tier with unlimited data and no ads, open-source apps, and independent audits. While it's one of the more transparent providers, its renewal pricing nearly triples the initial rate, and its Swiss jurisdiction - though strong - is not immune to legal pressure, as shown by a 2021 case involving its sibling service, Proton Mail.

Logging & privacy

Proton VPN claims a strict no-logs policy under Swiss jurisdiction, backed by two independent audits from Securitum (2023 and 2024) covering app and infrastructure security. These audits support its no-logs claim, elevating it above policy-only vendors. However, Swiss law is not absolute: in 2021, Proton Mail was compelled to log an activist’s IP, proving accounts tied to real identities can be subject to legal orders. There is no warrant canary, and while the audits are public, the Secure Core infrastructure remains unaudited and opaque.

Pricing & the renewal trap

The two-year plan starts at approximately $3.59/month, but renews at the then-current annual rate - effectively around $9.99/month, a 180% increase. The contract locks you in for 730 days with a 30-day refund window. You can pay anonymously via Bitcoin or Monero, and no KYC is required. The free tier offers unlimited data on one device across roughly five countries, making it one of the few truly functional free options. The real three-year cost, if renewed, exceeds $360.

Features & performance

Proton supports WireGuard, OpenVPN, IKEv2, and its proprietary Stealth protocol, which obfuscates traffic to bypass censorship. It offers a kill switch, split tunneling, multihop, Tor over VPN, and dedicated IP options. P2P and streaming are supported. The apps are open-source, and devices include Windows, Mac, Linux, Android, iOS, and major TV platforms. Server count is unverified, but coverage spans 145 countries. Real-world performance varies - some users report speeds below 25 Mbps, though this may depend on location and protocol.

Ownership & track record

Proton AG, based in Plan-les-Ouates, Switzerland, operates Proton VPN. There is no indication of conglomerate ownership, but the company has faced community scrutiny over CEO Andy Yen’s political commentary, which briefly rattled trust in 2024. In 2022, Proton removed Indian servers rather than comply with a government directive to log user data for five years. The 2021 Proton Mail incident showed that even Swiss providers can be forced to log under specific legal orders, reminding users that no service is beyond jurisdictional reach.

Censorship resistance

Proton VPN includes Stealth, a protocol that wraps OpenVPN and WireGuard in TLS to mimic HTTPS traffic, helping evade detection in censored networks like Egypt. It also uses “alternative routing” when direct connections are blocked. The 2026 launch of ProTUN, a Rust-based WireGuard implementation, aims to improve long-term resilience. While not proven in China or Iran, user reports confirm it works under moderate censorship. However, for high-risk environments, it should not be relied upon without additional layers.

Verdict

Proton VPN is a solid choice if you value open-source transparency, real audits, and a usable free tier. It’s especially strong for users in moderately censored regions. But you pay a steep renewal price, and its ownership of the affiliate program via PartnerStack means many reviews you read are likely paid promotions - so treat glowing rankings with skepticism.
