ProtonVPN is a virtual private network service developed by Proton AG, the company behind Proton Mail. Designed with privacy and security as primary goals, ProtonVPN combines robust technical safeguards with a clear focus on user trust. Based in Switzerland, it benefits from strong privacy laws and operates under a jurisdiction that is generally protective of user rights. Core features Encryption and protocols: ProtonVPN supports modern, secure VPN protocols including WireGuard, OpenVPN, and IKEv2. It uses strong encryption to protect data in transit and implements features like perfect forward secrecy to limit the impact of any potential key compromise. Secure Core: One of ProtonVPN’s distinctive offerings is Secure Core — a multi-hop architecture that routes traffic through privacy-friendly countries before it exits to the internet. This helps guard against network-level attacks and makes correlation significantly harder for adversaries. No-logs and transparency: ProtonVPN maintains a strict no-logs policy, meaning it does not collect activity logs that could identify you. The company has published transparency reports and open-source apps, contributing to a higher degree of auditable trust. Privacy and safety features Kill switch and leak protection: ProtonVPN includes a kill switch that blocks traffic if the VPN connection drops, plus DNS and IPv6 leak protection to prevent unintended exposure of your IP or DNS queries. P2P and streaming: Many ProtonVPN servers support P2P traffic, and the service is often able to access geo-restricted streaming libraries. Performance for streaming depends on server choice and network conditions, but ProtonVPN's higher-tier plans include faster servers and streaming-optimized nodes. Free and paid plans ProtonVPN offers a free tier with limited server access and speeds, which is notable for being relatively generous compared to some other free VPNs. Paid plans add access to Secure Core, faster speeds, more server locations, simultaneous connections, and advanced features. Pricing varies by plan and billing period. Ease of use and platforms ProtonVPN provides native apps for Windows, macOS, Linux, Android, and iOS, plus configuration guides for routers. The interfaces are user-friendly for beginners, while advanced users can customize protocol and routing options. Considerations No VPN guarantees full anonymity; ProtonVPN enhances privacy and security but should be combined with good practices (encrypted services, strong passwords, and caution with personal data). Users with specific threat models should evaluate features like multi-hop routing and jurisdictional protections. Conclusion ProtonVPN is a strong choice for users seeking a privacy-centric, transparent VPN with modern protocols, useful safety features, and a reputable background. Whether you choose the free tier for basic protection or a paid plan for higher performance and advanced features, ProtonVPN offers a compelling balance of privacy, usability, and trustworthiness.
