ProtonVPN is a virtual private network service developed by Proton AG, the same team behind Proton Mail. Built with privacy at its core and headquartered in Switzerland, ProtonVPN aims to give users secure, private access to the internet while minimizing data collection and exposure to surveillance. Key features and privacy protections - Jurisdiction and no-logs stance: Being based in Switzerland provides strong privacy protections under local law. ProtonVPN maintains a strict no-logs policy, meaning it does not store records of user activity or connection metadata that could be used to identify users. - Strong encryption and modern protocols: ProtonVPN supports industry-standard encryption (AES-256) and contemporary VPN protocols, including WireGuard, OpenVPN, and IKEv2. WireGuard is typically offered as the fastest option, while OpenVPN and IKEv2 provide broad compatibility. - Secure Core architecture: One distinctive feature is Secure Core, which routes traffic through multiple privacy-friendly servers (often in countries like Switzerland and Iceland) before it exits to the public internet. This provides extra protection against compromised or malicious exit servers. - Kill switch, DNS leak protection, and split tunneling: ProtonVPN apps include a kill switch that blocks internet access if the VPN connection drops, and built-in protections against DNS and IPv6 leaks. Split tunneling is available on some platforms to route selected apps outside the VPN. - Tor over VPN and P2P support: ProtonVPN can route traffic into the Tor network from specific servers, simplifying access to .onion sites without a separate Tor browser. P2P file sharing is allowed but limited to designated servers to balance performance and legal risk. Plans, speed, and usability ProtonVPN offers a free tier with access to a limited set of servers and moderate speeds, making it a good entry point for casual users. Paid plans add more countries, faster connections, Secure Core, streaming-optimized servers, and multiple simultaneous connections. Performance is generally competitive; WireGuard often yields the best throughput, while Secure Core routing can add latency as a trade-off for stronger privacy. Transparency and audits ProtonVPN’s clients are open-source and the service has participated in independent security audits, helping to increase transparency and trustworthiness. Who ProtonVPN is for ProtonVPN is well suited to privacy-conscious users, journalists, activists, and people who want a reputable VPN with transparent practices. It’s also a solid choice for users who want a free tier before committing to a paid plan. Those who need the absolute fastest speeds or specialized enterprise features may consider alternatives, but ProtonVPN’s balance of privacy, features, and usability makes it a strong general-purpose option.
