ProtonVPN is a virtual private network service developed by Proton Technologies, the team behind ProtonMail. It aims to provide a balance of strong privacy protections, solid performance, and transparent practices. Built around principles of user privacy and security, ProtonVPN is headquartered in Switzerland, a country with favorable privacy laws, and it emphasizes a strict no-logs policy, audited apps, and open-source client software. Core features - Strong encryption and protocols: ProtonVPN uses industry-standard encryption (AES-256) and supports secure tunneling protocols such as OpenVPN, IKEv2, and WireGuard. These technologies encrypt your internet traffic to prevent eavesdropping on public Wi‑Fi and by ISPs. - Secure Core routing: A distinctive feature, Secure Core routes traffic through privacy-friendly countries and ProtonVPN-controlled servers before exiting to the public internet. This design protects users against network-based attacks and makes correlation attacks far harder. - No-logs policy and jurisdiction: ProtonVPN’s no-logs claim is central to its privacy promise. Being based in Switzerland gives it protections against many foreign data requests, although it will comply with Swiss law where applicable. - Open-source and audited apps: ProtonVPN’s apps and back-end components have been progressively audited by third parties, and much of the client software is open source, allowing independent verification of security claims. - Kill switch and split tunneling: The kill switch prevents IP leaks by blocking network access if the VPN disconnects. Split tunneling (available on some platforms) lets you route specific apps outside the VPN when needed. - Free tier and paid plans: ProtonVPN offers a free plan with limited servers and speed, which is generous compared to many free VPNs because it does not inject ads. Paid tiers (Plus/Pro) unlock Secure Core, faster servers, streaming support, P2P/torrenting-friendly servers, and more simultaneous connections. - Tor over VPN: ProtonVPN can route traffic to the Tor network without a separate Tor Browser, simplifying anonymous browsing for users who require an extra layer of anonymity. Performance and usability ProtonVPN’s performance depends on plan level and server choice. Paid tiers provide higher-speed servers and support for WireGuard, which typically yields better throughput and lower latency. Native apps are available for Windows, macOS, Linux, Android, and iOS, with clear interfaces and straightforward setup. Use cases ProtonVPN is suited to privacy-conscious users, journalists, activists, and anyone who wants secure browsing on public networks. It also works well for streaming and torrenting on paid plans, and for users who prefer transparency and independent audits over flashy marketing claims. Considerations While ProtonVPN offers many strong privacy features, advanced users should read the provider’s policies and audit reports to confirm it meets their threat model. Costs for premium tiers are comparable to other reputable VPNs, though feature needs and geographic server coverage may influence choice. In summary, ProtonVPN is a credible option for users seeking a privacy-first VPN with transparent practices, robust security features, and both free and paid plans to match different needs.
