ProtonVPN is a virtual private network (VPN) developed by Proton AG, the same organization behind ProtonMail. Built with privacy as a central goal, ProtonVPN combines strong technical protections, a transparent development approach, and legal advantages from being headquartered in Switzerland, a country with robust privacy laws. Key features - No-logs policy: ProtonVPN states it keeps no activity logs that could identify what users do online. This reduces the risk of user data being exposed to third parties. - Secure Core servers: Unique to ProtonVPN, Secure Core routes traffic through multiple privacy-friendly countries before reaching the public internet, adding an extra layer of protection against network-level surveillance. - Modern protocols: ProtonVPN supports WireGuard, along with OpenVPN and IKEv2. WireGuard offers a good balance of speed and security on most platforms. - Open-source apps and audits: ProtonVPN’s clients are open-source and have undergone external security audits, increasing transparency and allowing the community to inspect the code. - Kill switch and leak protection: Built-in kill switch functionality and DNS leak protection help prevent accidental exposure of user IP addresses if the VPN connection drops. - Platform support: Native apps are available for Windows, macOS, Linux, Android, and iOS, along with manual setup options for routers and other devices. - Streaming and P2P: ProtonVPN supports streaming on many servers and allows P2P file sharing on designated nodes, though performance varies by region and plan level. Plans and performance ProtonVPN offers a free tier with limited servers and speeds, useful for casual or privacy-conscious users who don’t need high-bandwidth performance. Paid tiers unlock faster speeds, access to Secure Core and streaming/P2P-optimized servers, and additional simultaneous connections. Performance depends on factors such as server load, distance to the server, and the chosen protocol; WireGuard typically delivers the best speeds. Privacy considerations Being based in Switzerland can add legal protections compared to providers headquartered in data-sharing jurisdictions. ProtonVPN’s public privacy policy and independent audits contribute to trustworthiness, but users should still review terms and available guarantees for their specific threat model. Use cases ProtonVPN is well suited for users who prioritize privacy and want a transparent provider, journalists and activists operating under restrictive regimes, people who stream geo-restricted content, and anyone seeking secure public Wi‑Fi use. Conclusion ProtonVPN combines a privacy-first philosophy with robust technical features and cross-platform support. It’s a strong option for users who want a trustworthy VPN backed by transparency and security-focused design.#1#
