ProtonVPN is a privacy-focused virtual private network developed by the team behind ProtonMail. Built with a strong emphasis on user privacy, open-source software, and transparent policies, ProtonVPN aims to provide a trustworthy option for people who want secure internet access without sacrificing usability. Privacy and jurisdiction ProtonVPN is headquartered in Switzerland, a jurisdiction with strong privacy protections and no mandatory data-retention laws. The service operates under a strict no-logs policy and has published independent security audits of its apps and infrastructure. Proton’s transparent approach and Swiss base make it attractive for privacy-conscious users. Security and protocols ProtonVPN supports modern protocols including WireGuard, OpenVPN, and IKEv2. It uses industry-standard encryption such as AES-256 to protect traffic. Notable security features include a system-wide kill switch, DNS leak protection, and IPv6 leak prevention. ProtonVPN’s apps are open source, enabling independent review of the client code. Unique features - Secure Core: Traffic can be routed through multiple privacy-friendly countries (Secure Core servers) before exiting to the public internet, hardening protection against network-level surveillance. - Tor over VPN: Direct access to the Tor network from within the VPN client for added anonymity without needing a separate Tor Browser. - Split tunneling: Choose which apps send traffic through the VPN and which access the internet directly (available on select platforms). - P2P support: Dedicated servers allow torrenting on permitted nodes. - Streaming: Many ProtonVPN servers are optimized for streaming and can access popular services, though streaming availability can change. Free vs paid plans ProtonVPN offers a limited free tier that provides medium-speed access to a small number of server locations without data caps—useful for basic privacy needs. Paid plans (Plus, Visionary, etc.) unlock WireGuard performance, Secure Core, more server locations, higher speeds, simultaneous connections, and expanded streaming/P2P capabilities. Performance and limitations ProtonVPN provides competitive speeds, especially when using WireGuard on well-provisioned servers. However, performance can vary by location and time of day. Some streaming services occasionally block VPN IPs, so access can be inconsistent. Who should use it ProtonVPN is a strong choice for privacy-focused users, journalists, activists, or anyone who values transparency and strong jurisdictional protections. The free tier is good for casual use; paid plans suit users who need higher performance, streaming, and advanced privacy features. Getting started Download the official app for Windows, macOS, Linux, Android, or iOS from Proton’s website, create an account (free or paid), choose a server or feature like Secure Core, and connect. Verify the connection using an IP-check or DNS-leak test. In summary, ProtonVPN is a reputable, privacy-first VPN with robust security features and transparent practices, making it a dependable option for users who prioritize confidentiality and trustworthiness.#1#
