ProtonVPN is a virtual private network service developed by Proton AG, the company behind Proton Mail. Designed with privacy as its central focus, ProtonVPN combines strong encryption, a clear privacy policy, and a suite of features aimed at protecting users on public and private networks alike. Security and privacy model ProtonVPN uses industry-standard protocols (including WireGuard and OpenVPN) and strong cryptography to secure data in transit. Clients support a system-wide kill switch and DNS leak protection to prevent accidental exposure if a connection drops. The service operates under Swiss jurisdiction, which affords robust privacy protections and is not part of the Fourteen Eyes surveillance alliances. Proton emphasizes transparency: its apps are open source and the company publishes transparency reports and has undergone independent security assessments for parts of its infrastructure. Unique features One of ProtonVPN’s signature features is Secure Core routing. Secure Core routes traffic through privacy-friendly servers located in countries with strong privacy laws before leaving the VPN network, adding an extra layer of protection against network-level attackers. ProtonVPN also offers NetShield, a built-in DNS-level filter that blocks trackers, ads, and known malware domains. Additional conveniences include split tunneling (on supported platforms), Tor-over-VPN access to .onion sites, and P2P-optimized servers for safer file sharing. Plans and accessibility ProtonVPN provides a range of plans, from a basic free tier with access to a limited set of servers, up to paid plans that unlock high-speed servers, Secure Core, NetShield, and more simultaneous connections. Apps are available for Windows, macOS, Linux, iOS, and Android; there are also setup guides for routers and other platforms. The free tier makes ProtonVPN accessible for casual users who want basic protection, while paid tiers are aimed at power users who need higher speeds and additional privacy features. Performance and use cases With global servers and support for modern protocols like WireGuard, ProtonVPN can deliver competitive speeds for streaming, remote work, gaming, and secure browsing. It’s particularly well-suited for users who prioritize privacy over raw convenience — journalists, activists, and privacy-minded consumers — but it’s also practical for anyone who uses public Wi‑Fi or needs to access geo-restricted content. Conclusion ProtonVPN strikes a balance between strong privacy protections and user-friendly design. Its Swiss base, open-source clients, and feature set—Secure Core, NetShield, Tor support, and modern protocols—make it a compelling option for users seeking a transparent, security-focused VPN. As always, match a VPN’s features and jurisdiction to your specific needs before subscribing.
