ProtonVPN is a virtual private network service developed by Proton AG, the same organization behind Proton Mail. Built with a strong focus on privacy and transparency, ProtonVPN aims to give users a secure, easy-to-use way to encrypt their internet traffic, hide their IP address, and bypass censorship or geo-restrictions. Privacy and jurisdiction One of ProtonVPN’s defining characteristics is its Swiss jurisdiction. Switzerland has robust privacy laws and is not part of major intelligence-sharing alliances, which can make it a favorable base for privacy tools. ProtonVPN also publishes a clear privacy policy and claims a strict no-logs approach, meaning it does not store records of users’ online activity. Security and technical features ProtonVPN supports modern VPN protocols such as WireGuard, as well as OpenVPN and IKEv2, providing a balance of speed and security. Many of its servers are RAM-only (diskless), so stored data is wiped on reboot, reducing the risk of persistent logs. ProtonVPN also offers a “Secure Core” feature that routes traffic through multiple servers in privacy-friendly countries before it exits to the public internet, adding an extra layer of protection against network-based attacks and surveillance. Additional protections include a system-wide kill switch that prevents IP leaks if the VPN connection drops, DNS leak protection, and, on some platforms, split tunneling to control which apps use the VPN. ProtonVPN’s apps are open source and have undergone independent security audits, contributing to transparency and trust. Plans, free tier, and performance ProtonVPN provides a free tier with access to a limited set of servers and basic features, which is useful for casual users who want privacy without cost. Paid plans unlock faster servers, Secure Core, streaming-optimized locations for services like Netflix, and P2P/torrenting support. Speeds are generally competitive, especially when using WireGuard, but actual performance varies with server load and geographic distance. Usability and platforms Apps are available for Windows, macOS, Linux, iOS, Android, and some routers. The interfaces are straightforward, making ProtonVPN suitable for both beginners and advanced users who need configurable settings. When to choose ProtonVPN Choose ProtonVPN if you prioritize privacy-minded ownership, strong encryption, and features like Secure Core and audited, open-source apps. Consider a paid plan for faster speeds, broader server access, and streaming/P2P needs. As with any VPN, evaluate your threat model and test the service with a short trial or the free plan to ensure it meets your expectations.
