ProtonVPN is a privacy-focused virtual private network developed by Proton AG, the company behind Proton Mail. Built around strong encryption, a transparent development model, and a strict no-logs stance, ProtonVPN aims to give users secure, private access to the internet while remaining easy to use for beginners and powerful enough for advanced users. Core privacy and security ProtonVPN operates under Swiss jurisdiction, which provides robust data-protection laws and an independent legal environment. The service advertises a strict no-logs policy and has made large parts of its apps open source so security researchers can inspect the code. ProtonVPN also undergoes third‑party security audits to validate its claims. Standard protections include AES-256 encryption, secure VPN protocols (WireGuard and OpenVPN), a kill switch to block traffic if the VPN drops, and DNS leak protection. Unique features One standout feature is Secure Core: traffic is routed through multiple servers in privacy-friendly countries before exiting to the public internet, adding protection against network-level adversaries. ProtonVPN also supports Tor over VPN, enabling direct access to the Tor network without running the Tor browser separately. NetShield is ProtonVPN’s built-in DNS-level filter that can block ads, trackers, and known malware domains, improving privacy and performance in some cases. Plans and usability ProtonVPN offers a free tier with limited servers and speeds, making it a good option for users who want basic encrypted access without commitment. Paid tiers unlock faster servers, access to Secure Core, streaming-optimized locations, P2P/torrent-friendly servers, and simultaneous device connections. The apps for Windows, macOS, Linux, Android, and iOS are designed for simplicity, with one-click connections, server search and filtering, and custom profiles for power users. Performance and limitations Performance varies by server load, distance, and chosen protocol; WireGuard typically provides the best balance of speed and security. While ProtonVPN is suitable for streaming and P2P in many regions, users dependent on ultra-high speeds or specialized geo-unblocking may want to test it with the specific services they use. Who should choose ProtonVPN Choose ProtonVPN if your priorities are privacy, transparency, and a provider with a strong reputation for security. It’s a solid pick for journalists, activists, frequent travelers using public Wi‑Fi, and anyone who prefers a privacy-first company based in a favorable jurisdiction. If maximum speed or lowest price are your only concerns, compare trials and benchmarks against other top VPNs to find the best match.
