Proton VPN is a VPN service launched in 2017 and operated by the Swiss company Proton AG, the company behind the email service Proton Mail.[1] According to its official website, Proton VPN and Proton Mail share the same management team, offices, and technical resources, and are operated from Proton's headquarters in Plan-les-Ouates, Switzerland.[2] On June 17, 2024, the company announced that it will be transitioning to a non-profit structure under the Proton Foundation.[3]
As of 18 February 2026, Proton VPN has a total of 18,166 servers, sited in 129 different nations.[4]
Although Proton VPN owns and operates a portion of their servers, the bulk majority are owned and operated by ASNs such as M247 and Datacamp Limited.[5] Its service is available for Windows, MacOS, Linux, Android, iOS, and ChromeOS and also has a command-line tool[6] for Linux and can be implemented using the IPsec protocol.[7] Proton VPN can also be installed on a wireless router.
Proton VPN utilizes OpenVPN (UDP/TCP), IKEv2, and WireGuard (UDP/TCP) protocols with AES-256 encryption. On October 11, 2022, Proton VPN released their Stealth Protocol for Android, iOS and MacOS clients, designed to disguise VPN traffic as HTTPS traffic.[8] In August 2024, Proton VPN announced that it had also added the Stealth protocol to its Windows client.[9]
Proton VPN has a no-logs policy that was independently audited by Securitum, a European security auditing company.[10] [11] [12]
In January 2020, Proton VPN released its source code on all platforms[13] and had SEC Consult conduct an independent security audit.[14]
In March 2025, Vivaldi integrated Proton VPN into its desktop app, offering the free tier of Proton VPN to all Vivaldi users.[15] [16]
In a January 2023 review by TechRadar, Proton VPN received 4-1/2 out of 5 stars.[17] A May 2023 PC Magazine review gave Proton VPN a 5-star rating. Proton VPN was awarded their Editor's Choice Award in 2022 and 2023.[18] In October 2023 technology website Engadget rated Proton VPN as the "best overall" for streaming, gaming, privacy and security.[19] In January 2024 a comparative review of 10 different VPNs by German technology magazine CHIP rated Proton VPN as their test winner.[20] In a 2025 TechRadar review of travel VPN services, Proton VPN was ranked second overall and described as the "best VPN for privacy," with emphasis on its Swiss jurisdiction, independent audits, no-logs policy, and advanced security features.[21]
