ProtonVPN is a virtual private network service created by Proton AG, the same team behind Proton Mail. Basing its operations in Switzerland, ProtonVPN emphasizes privacy, transparency, and strong technical safeguards to protect users’ online activity from surveillance, tracking, and censorship. At its core, ProtonVPN provides encrypted tunnels between your device and the internet, hiding your IP address and shielding your traffic on untrusted networks such as public Wi‑Fi. The service supports modern VPN protocols including WireGuard and traditional options like OpenVPN and IKEv2, giving users a balance of speed and compatibility across Windows, macOS, Linux, Android, iOS, and many routers. One of ProtonVPN’s signature features is Secure Core — a multi-hop routing system that routes traffic through privacy-friendly countries before it exits to the wider internet. Secure Core servers are hosted in jurisdictions with strong privacy protections and on physically secure infrastructure, adding an extra layer of defense against network-based attacks and IP correlation attempts. For privacy-conscious users or those in hostile network environments, Secure Core can significantly reduce the risk of deanonymization. ProtonVPN also supports Tor over VPN, which directs traffic into the Tor network without requiring users to run the Tor Browser directly. This is useful for combining VPN encryption with Tor’s anonymity layer. Additionally, ProtonVPN allows P2P traffic on selected servers, making it suitable for torrenting when used responsibly. Transparency is a strong theme: ProtonVPN’s apps are open-source and have undergone independent security audits. The company enforces a strict no-logs policy and benefits from Switzerland’s favorable privacy laws, which limit how user data can be accessed by governments. Other practical protections include a kill switch to block traffic if the VPN connection drops, DNS leak protection, and split tunneling on supported platforms so you can route some apps outside the VPN. ProtonVPN offers both free and paid plans. The free tier provides foundational privacy protection with access to a limited set of servers and moderate speeds, making it a good starting point for users who want to test the service without cost. Paid plans unlock higher speeds, access to more servers and countries, Secure Core and Tor features, simultaneous connections, and streaming-optimized servers. While no VPN can offer perfect anonymity, ProtonVPN combines strong technical features, transparent practices, and a privacy-friendly jurisdiction to deliver a compelling option for users seeking better online privacy, security, and the ability to bypass content restrictions. For most users, it’s worth testing the free tier and upgrading if advanced features or higher performance are needed.
