ProtonVPN is a virtual private network service created by Proton AG, the company best known for ProtonMail. Launched with a strong privacy ethos, ProtonVPN emphasizes security, transparency, and user control. Its design reflects the company’s broader mission to protect online privacy through tools that minimize data collection and maximize user trust. One of ProtonVPN’s standout features is Secure Core. Unlike a standard VPN that routes traffic through a single external server, Secure Core routes traffic through multiple servers located in privacy-friendly jurisdictions (typically in Switzerland, Iceland, or Sweden) before exiting to the wider internet. This adds an extra layer of protection against certain network-based attacks and surveillance, particularly if an exit server is compromised. ProtonVPN supports modern, well-reviewed protocols such as WireGuard, OpenVPN, and IKEv2, with strong encryption (e.g., ChaCha20-Poly1305 or AES-256) to protect data in transit. The apps are open-source and have undergone third-party audits, which enhances transparency and allows security researchers to inspect the code. The company also follows a strict no-logs policy and is based in Switzerland, a jurisdiction with robust privacy laws that can be more protective than many alternatives. The service offers a range of plans, including a free tier that provides access to a limited set of servers without data caps — a useful way to try the service before committing. Paid plans unlock faster servers, access to streaming-optimized and P2P-friendly servers, Secure Core, and support for more simultaneous connections. ProtonVPN provides apps for Windows, macOS, Linux, Android, and iOS, plus configuration options for routers and command-line usage. Features commonly expected from modern VPNs are present: a kill switch to block traffic if the VPN connection drops, split tunneling on some platforms, and DNS leak protection. ProtonVPN is well-suited for privacy-conscious users, journalists, and people traveling on unsecured networks. It also supports torrenting on designated servers and can help access region-restricted streaming libraries, although some streaming features may be limited to higher-tier plans. Considerations: ProtonVPN’s network size can be smaller than some large competitors, and top speeds may be reserved for paid tiers. Pricing is competitive but may be higher than budget VPNs, reflecting its privacy-first positioning. In summary, ProtonVPN is a solid choice if your priority is privacy, transparency, and strong technical protections. Try the free plan to evaluate performance and features for your particular use cases before upgrading to a paid tier.
