ProtonVPN is a virtual private network service developed by Proton AG, the same Swiss company behind Proton Mail. Built with privacy as a priority, ProtonVPN combines strong encryption, a transparent development approach, and a suite of features designed to protect users on public Wi‑Fi, when torrenting, or while accessing geo-restricted content. Core features ProtonVPN uses industry-standard encryption and modern VPN protocols (including WireGuard and OpenVPN/IKEv2 where applicable) to secure traffic between your device and VPN servers. It offers a kill switch to block internet access if the VPN connection drops and DNS leak protection to ensure queries don’t reveal your activity. Apps are open-source, allowing independent inspection of the client code and improving trust through transparency. Secure Core and Swiss jurisdiction One of ProtonVPN’s distinguishing features is Secure Core: traffic is routed through multiple servers located in privacy-friendly countries (for example, Switzerland and Iceland) before exiting to the wider internet. This architecture makes it harder for adversaries to trace connections back to users even if an exit server is compromised. Being based in Switzerland is also beneficial because Swiss privacy laws are strong, and the company has a firm commitment to user privacy. Privacy policy and audits ProtonVPN advertises a strict no-logs policy, meaning it does not retain records of users’ online activity. The company emphasizes transparency and has made parts of its infrastructure and apps publicly available for inspection; periodic independent audits and published transparency reports further bolster confidence. Plans and performance ProtonVPN provides a free tier that offers basic protection with limited server selection and speeds — useful for casual users. Paid tiers unlock faster servers, more simultaneous connections, Secure Core, P2P-enabled servers, and additional premium features like Tor over VPN and dedicated streaming servers. Like all VPNs, actual speeds vary by server load, distance, and protocol; choosing nearby servers or WireGuard can improve performance. Use cases and compatibility Common uses include protecting data on public Wi‑Fi, bypassing regional content blocks for streaming, securing torrenting on P2P servers, and preserving anonymity while browsing. ProtonVPN supports major platforms—Windows, macOS, Linux, Android, iOS—and can be configured on certain routers for whole-network protection. Conclusion ProtonVPN is a solid choice for users who prioritize privacy and transparency. Its Secure Core concept and Swiss base set it apart, and the combination of open-source clients, a free tier, and paid plans for advanced needs makes it suitable for a wide range of users — from privacy-conscious individuals to those seeking better access to streaming or secure P2P usage.
