ProtonVPN is a virtual private network service developed by Proton AG, the same Swiss team behind ProtonMail. Built with privacy and security as primary goals, ProtonVPN aims to give users a trustworthy way to protect their internet traffic, bypass censorship, and access geo-restricted content while maintaining control over personal data. Key features and security ProtonVPN employs industry-standard encryption (AES-256) and supports modern VPN protocols, including WireGuard, OpenVPN, and IKEv2. WireGuard typically provides better speeds and lower overhead, and ProtonVPN’s implementation is designed to balance performance with privacy. The service also includes a kill switch that blocks internet access if the VPN connection drops, DNS leak protection, and split tunneling on supported platforms to route selected apps outside the VPN. A standout feature is Secure Core, which routes connections through privacy-friendly countries (such as Switzerland and Iceland) before exiting to the wider internet. This multi-hop approach helps protect against network-level surveillance and certain types of attack that trace traffic back to the source. ProtonVPN also supports Tor over VPN, allowing users to connect to the Tor network via a VPN tunnel for added anonymity. Privacy and transparency ProtonVPN is headquartered in Switzerland, benefiting from strong privacy laws and being outside the 14 Eyes surveillance alliance. The company maintains a strict no-logs policy, meaning it does not store user activity or session metadata that could be used to identify users. ProtonVPN’s applications are open source, and the service has undergone external security audits, enhancing transparency and trust. Plans and use cases ProtonVPN offers a free tier with limited servers and moderate speeds — useful for casual privacy needs — alongside several paid tiers that unlock faster speeds, more server locations, Secure Core, streaming-optimized servers, and simultaneous connections. Paid plans are suitable for frequent travelers, journalists, remote workers, and anyone who regularly uses public Wi-Fi or needs to access region-locked content. Limitations While ProtonVPN is competitive on privacy and security, it may have fewer servers than some larger commercial VPNs, and performance can vary depending on server load and user location. Premium plans are pricier than some budget options, but they include advanced privacy features and the backing of a privacy-focused company. Conclusion ProtonVPN is a solid option for users who prioritize privacy and transparency. Its Swiss jurisdiction, no-logs stance, Secure Core routing, audited open-source apps, and Tor integration make it particularly attractive for privacy-conscious users, while the free tier allows newcomers to try the service before upgrading.#1#
