ProtonVPN is a virtual private network service developed by Proton AG, the makers of ProtonMail. Designed with privacy at its core, ProtonVPN aims to provide secure, easy-to-use internet access for users concerned about surveillance, censorship, or data collection. Its background in encrypted email sets a high bar for cryptographic standards and transparency. Key features include AES-256 encryption with modern VPN protocols (WireGuard and OpenVPN), a strict no-logs policy, and a Swiss legal base that benefits from strong privacy laws. For additional protection, ProtonVPN offers Secure Core — a multi-hop routing option that passes traffic through multiple servers located in countries with strong privacy protections before it reaches the public internet. This makes correlation attacks and targeted surveillance far more difficult. ProtonVPN also supports Tor over VPN, allowing users to route their traffic into the Tor network with a single click. Other practical protections include an automatic kill switch to block traffic if the VPN connection drops, DNS leak protection, split tunneling on some platforms, and customizable connection profiles. The company publishes its mobile and desktop apps as open-source software and has undergone independent security audits, which bolsters trust in its implementation. One attractive aspect is the free tier. ProtonVPN’s free plan offers unlimited bandwidth (with lower priority and limited server access), making it a useful option for casual, privacy-minded users who don’t need top speeds. Paid plans expand server access, unlock Secure Core and Tor features, allow multiple simultaneous connections, and improve streaming and torrenting capabilities. Performance-wise, ProtonVPN has improved considerably, especially with WireGuard support, which provides faster speeds and lower latency compared to older protocols. However, actual performance depends on server location, plan tier, and local network conditions — premium servers typically deliver the best results. Limitations to consider: premium features require a paid subscription; some advanced functions differ between operating systems; and while ProtonVPN has a strong privacy record, no VPN can guarantee absolute anonymity. Users with extreme threat models should combine VPN use with other privacy practices. In summary, ProtonVPN is a solid choice for users prioritizing transparency, privacy, and security. Its feature set — Secure Core, Tor integration, audited open-source apps, and a commitment to privacy under Swiss law — makes it particularly appealing to users who want a trustworthy, well-engineered VPN solution.#1#
