ProtonVPN is a virtual private network service created by the team behind ProtonMail, designed to give users control over their online privacy and security. Headquartered in Switzerland, a country with strong privacy laws, ProtonVPN emphasizes transparency, strong cryptography, and user choice. It aims to protect users’ internet traffic from surveillance, ISP tracking, and insecure public Wi‑Fi networks. Core features and security ProtonVPN uses industry-standard protocols including WireGuard, OpenVPN, and IKEv2, with modern cipher suites to secure traffic. WireGuard delivers fast connection speeds and strong security, while OpenVPN and IKEv2 provide compatibility and stability across a wide range of devices. ProtonVPN’s apps are open-source and have undergone third-party audits, boosting trust through verifiable code and independent security assessments. One distinctive feature is Secure Core routing: when enabled, traffic is routed through multiple servers in privacy-friendly countries (such as Switzerland and Iceland) before exiting to the public internet. This adds an extra layer of protection against advanced network-based threats and some forms of endpoint adversaries. ProtonVPN also supports Tor over VPN, allowing users to access the Tor network with a single click, and includes a reliable kill switch to prevent leaks if the VPN connection drops. Privacy and logging ProtonVPN operates a strict no-logs policy, meaning it does not record user activity or connection metadata that could identify individuals. Being based in Switzerland helps shield the service from invasive intelligence-sharing agreements, though no service can offer absolute protection against every legal scenario. ProtonVPN’s transparency reports and independent audits help verify its privacy claims. Plans and usability ProtonVPN provides both a free tier and several paid plans. The free plan gives access to a limited number of servers with moderate speeds—useful for basic privacy needs—while paid plans unlock faster servers, Secure Core, streaming-optimized servers, and support for more simultaneous connections. Apps are available for Windows, macOS, Linux, Android, iOS, and some routers, with a simple interface that balances ease of use for newcomers and advanced settings for experienced users. Use cases ProtonVPN is well-suited to people who want dependable privacy protection on public Wi‑Fi, journalists and activists who need extra safeguards, and everyday users who want to improve online security without sacrificing usability. Its streaming and P2P-friendly servers also appeal to users who need reliable access to geo-restricted content. In summary, ProtonVPN combines strong technical fundamentals with a privacy-centric philosophy, making it a solid option for users seeking a trustworthy, feature-rich VPN from a reputable provider.
