Proton VPN Full Review for UK Users
Proton VPN is the privacy-focused VPN from the team behind Proton Mail, the world's most popular encrypted email service. Based in Switzerland, which has some of the strongest privacy laws in the world and sits outside both EU and Five Eyes jurisdictions, Proton VPN has been built from the ground up as a privacy-first product.
As of 2026, Proton VPN boasts the most servers in the UK of any top provider, with 553 servers across five locations. These servers deliver outstanding performance, with speeds of 1,521 Mbps recorded on a 10 Gbps UK line during independent testing. The Securitum audit conducted in 2025 verified that Proton VPN maintains a genuine no-logs policy.
What sets Proton VPN apart is its commitment to transparency and open source. All of its applications across every platform are fully open-source, meaning anyone can inspect the code for vulnerabilities or privacy concerns. This level of transparency is rare in the VPN industry and provides an additional layer of trust.
Proton VPN is one of the few premium VPN services to offer a genuinely useful free tier. The free plan provides unlimited data (a rarity among free VPNs) and access to servers in five countries, making it a solid choice for users who want basic privacy protection without paying anything.
Paid subscribers gain access to the full network of 9,000+ servers across 112 countries, plus advanced features like Secure Core (which routes traffic through privacy-friendly countries before reaching the destination), NetShield (an ad and tracker blocker), and Tor over VPN support.
As a bonus, Proton VPN subscribers on the Proton Unlimited plan also receive access to Proton Mail, Proton Drive (up to 5GB encrypted storage), Proton Calendar, and Proton Pass password manager, creating a comprehensive privacy ecosystem that no other VPN provider can match.
