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. Its service is available for Windows, MacOS, Linux, Android, and iOS, ChromeOS and also has a command-line tool for Linux and can be implemented using the IPSEC protocol. Proton VPN can also be installed on a wireless router.

Proton VPN utilizes OpenVPN (UDP/TCP), IKEv2, and WireGuard 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. In March 2024, Proton VPN announced that it would be bringing the Stealth Protocol to Windows in the summer.

Proton VPN has a no-logs policy that was independently audited by Securitum, a European security auditing company.

In January 2020, Proton VPN released its source code on all platforms and had SEC Consult conduct an independent security audit.
