ProtonVPN is a virtual private network service developed by the same team behind ProtonMail. Designed to prioritize privacy and security, it combines strong encryption, a strict no-logs policy, and features tailored to resist surveillance and censorship. Based in Switzerland, ProtonVPN benefits from favorable privacy laws and commitments to user confidentiality. Security and privacy ProtonVPN supports modern VPN protocols including WireGuard, OpenVPN, and IKEv2, giving users options that balance speed and compatibility. Its apps are open source, which increases transparency and enables independent security audits. Notable features include a system-wide kill switch that blocks all internet traffic if the VPN connection drops, DNS leak protection, and optional split tunneling on supported platforms. A standout capability is Secure Core, which routes traffic through multiple VPN servers in privacy-friendly jurisdictions before it exits to the internet. This approach adds an extra layer of protection against network-level attackers and compromised exit nodes. ProtonVPN also offers Tor over VPN (connecting through the Tor network) for users who want deeper anonymity without installing the Tor browser separately. Performance and servers ProtonVPN operates hundreds of servers across many countries worldwide, with "Plus" servers optimized for higher speeds, streaming, and P2P traffic. WireGuard support has significantly improved performance for many users, delivering faster connection times and lower latency compared with older protocols. Real-world speeds depend on server choice, distance, and local network conditions, but ProtonVPN provides server load indicators to help choose optimal connections. Plans and pricing ProtonVPN offers a free tier with a limited selection of servers and moderate speeds — useful for casual privacy needs and testing the service. Paid tiers unlock more servers, Secure Core, Tor over VPN, streaming-optimized servers, and support for more simultaneous devices. Pricing is tiered to suit different needs, from individual users to families and businesses, and Proton occasionally includes discounts for annual subscriptions. Use cases and limitations ProtonVPN is well-suited for protecting privacy on public Wi-Fi, securing remote work connections, accessing geo-restricted content, and evading basic forms of censorship. It is not a magic bullet; advanced adversaries may still correlate traffic patterns, and local laws determine what is permissible. Users should also be aware that certain streaming platforms may block VPNs, and success can vary by server. Conclusion ProtonVPN is a mature, privacy-focused VPN with strong technical foundations, transparent practices, and features that address both security-conscious users and everyday consumers. Its combination of Swiss jurisdiction, open-source clients, and advanced routing options like Secure Core make it a compelling option for those prioritizing confidentiality and reliability online.
