PN: Secure, Private, and User-Friendly VPN from Switzerland Keywords ProtonVPN, VPN, Proton AG, Secure Core, WireGuard, no-logs, privacy, free VPN, VPN for streaming, VPN for torrenting, Swiss privacy laws Description ProtonVPN is a Swiss-based VPN service offering strong encryption, a free plan, Secure Core servers, and privacy-first features for everyday and advanced users. Content ProtonVPN is a privacy-focused virtual private network developed by Proton AG, the same team behind Proton Mail. Founded with the goal of protecting online privacy and freedom, ProtonVPN combines strong encryption, a clear no-logs policy, and a set of advanced features designed to keep users secure without sacrificing usability. Core features and privacy ProtonVPN uses modern VPN protocols such as WireGuard, OpenVPN, and IKEv2 to secure connections. Encryption and authentication are industry-standard, protecting traffic from eavesdropping on public Wi‑Fi and other untrusted networks. A central selling point is ProtonVPN’s no-logs policy and Swiss jurisdiction: based in Switzerland, the company benefits from strong privacy laws and is not subject to EU or US surveillance rules. ProtonVPN also offers Secure Core servers — a multi-hop architecture that routes traffic through privacy-friendly countries (for example, Switzerland and Iceland) before exiting to the public internet, adding an extra layer of protection against network-level surveillance. Safety and extra protections ProtonVPN includes a kill switch that blocks internet traffic if the VPN connection drops, preventing IP leaks. Tor over VPN is supported, allowing users to route traffic through the Tor network directly from the VPN app. Some apps provide split tunneling to let users choose which apps use the VPN. ProtonVPN has made transparency and security a priority and has undergone independent security audits and public reporting, which reinforces trust in its implementation. Plans, pricing, and platform support ProtonVPN offers a free tier with access to a limited number of servers and moderate speeds — a useful option for users seeking basic protection without cost. Paid plans (Basic, Plus, Visionary) unlock faster speeds, access to all servers (including Secure Core and streaming-optimized servers), more simultaneous connections, and additional features such as access to Proton Mail bundled in some tiers. ProtonVPN provides native apps for Windows, macOS, Linux, Android, and iOS, as well as configuration guides for select routers. Performance and use cases Performance depends on server choice and plan level; paid users typically see much higher speeds thanks to high-bandwidth servers and WireGuard support. ProtonVPN is suitable for everyday privacy, secure browsing on public Wi‑Fi, geo-unblocking streaming services, and safe torrenting on P2P-enabled servers. Advanced users will appreciate Secure Core and Tor integration for higher threat models. Conclusion ProtonVPN is a compelling option for users who prioritize privacy and transparency. Its Swiss base, no-logs stance, and additional protections like Secure Core and Tor over VPN make it especially attractive to those seeking strong, user-friendly privacy tools. The free plan lowers the barrier to entry, while paid tiers add performance and features fo
