ProtonVPN is a virtual private network (VPN) service developed by the team behind ProtonMail, designed with a strong emphasis on privacy, security, and transparency. Headquartered in Switzerland — a country with robust privacy protections and favorable jurisdictional rules — ProtonVPN aims to give users secure, private internet access without logging or monetizing their data. Security and privacy lie at the heart of ProtonVPN’s offering. The service uses modern, secure protocols including WireGuard, OpenVPN, and IKEv2, combined with industry-standard encryption (AES-256) and perfect forward secrecy. ProtonVPN operates diskless (RAM-only) servers to prevent persistent data storage and supports a strict no-logs policy, which has been reinforced through independent audits and public transparency reports. The software is largely open source, allowing security researchers and users to inspect the code. A standout feature is Secure Core, a multi-hop architecture that routes traffic through a chain of privacy-friendly countries (such as Switzerland, Iceland, and Sweden) before exiting to the public internet. This approach helps protect against targeted surveillance and attacks that might try to trace traffic back to its origin. For users who want additional anonymity when accessing the Tor network, ProtonVPN provides built-in Tor over VPN functionality that sends traffic through Tor with a single click. ProtonVPN supports P2P traffic on selected servers, which is useful for safe torrenting. It also offers NetShield, an integrated ad, tracker and malware blocker that filters traffic at the DNS level. Additional conveniences include a reliable kill switch, split tunneling on supported platforms, and cross-platform apps for Windows, macOS, Linux, iOS, Android, and certain routers. ProtonVPN’s free tier provides a no-cost option with limited servers and speeds, making it accessible for casual users, while paid plans unlock faster servers, more simultaneous connections, Secure Core, and streaming-optimized locations. Where ProtonVPN shines is in trustworthiness and focus on user privacy rather than aggressive marketing or data-driven revenue models. The company’s ties to ProtonMail, its public audits, and its transparent privacy policies make it an attractive choice for privacy-conscious users, journalists, activists, and anyone operating under higher threat models. There are trade-offs. ProtonVPN typically offers fewer physical server locations than some larger competitors, and its higher-tier plans can be more expensive than budget-focused VPNs. Speeds can vary depending on server load and distance, though WireGuard and well-placed server infrastructure generally deliver competitive performance. In summary, ProtonVPN is a solid, privacy-centric VPN that balances strong technical protections with transparency. If your priorities are confidentiality, independent verification, and features like Secure Core or Tor integration, ProtonVPN deserves serious consideration. If you mainly need the lowest possible price and the widest global server coverage, compare offerings from other providers to find the best fit.
