ProtonVPN is a virtual private network service developed by Proton AG, the same Switzerland-based company behind Proton Mail. Designed with privacy and security at its core, ProtonVPN aims to give users a safe, private way to connect to the internet by encrypting traffic, hiding IP addresses, and routing connections through its global server network. Privacy and jurisdiction One of ProtonVPN’s strongest selling points is its Swiss jurisdiction. Switzerland has robust privacy laws and is outside EU and US intelligence-sharing agreements, which adds an extra legal layer of protection for user data. ProtonVPN operates under a strict no-logs policy; the company states it does not keep records of user activity. This privacy stance is reinforced by transparent practices such as open-source apps and public security documentation. Key features - Secure Core: ProtonVPN’s Secure Core routes traffic through multiple servers located in privacy-friendly countries (for example, Switzerland and Iceland) before exiting to the open internet. This design mitigates risks from compromised exit servers and helps protect against network-level surveillance. - Strong encryption and protocols: ProtonVPN supports modern, fast protocols like WireGuard and also offers OpenVPN. It uses robust encryption and forward secrecy to protect session data. - Tor over VPN: For users seeking extra anonymity, ProtonVPN provides easy integration with the Tor network so you can access .onion sites without a separate Tor browser. - Kill switch and leak protection: Built-in protections prevent IP and DNS leaks and can automatically disconnect your device if the VPN connection drops, preventing accidental exposure. - Split tunneling and platform support: ProtonVPN offers split tunneling on supported platforms, letting you choose which apps use the VPN. Native apps are available for Windows, macOS, Linux, iOS, and Android, plus guides for routers. - Streaming and P2P: Paid plans typically include servers optimized for streaming and P2P file sharing, improving performance for these use cases. Plans and free tier ProtonVPN provides multiple plans, including a free tier that allows basic, limited access to servers. Paid plans unlock faster servers, more countries, Secure Core, access to Tor servers, and simultaneous device support. For those who value privacy and need higher throughput for streaming or P2P, the mid- to high-tier plans are often the best fit. Performance and usability Thanks to WireGuard and a well-distributed server fleet, ProtonVPN delivers competitive speeds, though actual performance depends on server choice and location. The apps are user-friendly, making setup straightforward for beginners while offering advanced settings for experienced users. Conclusion ProtonVPN is a strong option for privacy-minded individuals. Its Swiss base, no-logs policy, Secure Core architecture, and modern protocols make it particularly attractive for users who prioritize security and transparency. Consider the free tier to test basic functionality, and upgrade if you need higher speeds, specialized servers, or additional privacy features.
