ProtonVPN positions itself as a privacy-first virtual private network created by Proton AG, the same team behind ProtonMail. Its primary selling points are strong encryption, a no-logs commitment, and features designed to defend users against surveillance and tracking. Based in Switzerland, ProtonVPN benefits from privacy-friendly laws and a reputation for transparency. Security and protocols ProtonVPN supports modern VPN protocols including WireGuard, OpenVPN, and IKEv2. WireGuard is often preferred for its speed and efficient codebase, while OpenVPN and IKEv2 provide compatibility and mature stability. All traffic is encrypted with robust ciphers, and apps include essential safeguards such as a system-wide kill switch and DNS leak protection to prevent accidental exposure of IP addresses. Unique features One standout ProtonVPN feature is Secure Core, which routes traffic through multiple servers in privacy-friendly countries before it reaches the public internet. This multi-hop approach increases resilience against network-level attacks and helps keep user locations harder to trace. ProtonVPN also offers Tor over VPN functionality for users who want seamless access to the Tor network without a separate Tor Browser. Split tunneling, dedicated IPs (on certain plans), and specialized streaming and P2P servers provide flexibility for different use cases. Privacy and transparency ProtonVPN adheres to a no-logs policy and has made parts of its service open source. The company has engaged independent security audits to validate its apps and infrastructure, and regularly publishes transparency reports. Being headquartered in Switzerland means ProtonVPN operates under strong privacy protections and outside the direct jurisdiction of some mass surveillance alliances. Plans and usability ProtonVPN has a tiered model: a limited free plan with access to a subset of servers, and multiple paid tiers that unlock faster speeds, Secure Core, more server locations, and additional simultaneous connections. Apps are available for Windows, macOS, Linux, Android, iOS, and some routers, and they feature user-friendly interfaces suitable for beginners while still exposing advanced options for power users. Performance and limitations Performance is generally competitive, especially when using WireGuard, but speeds can vary depending on server load and location. Because advanced features like Secure Core add routing steps, multi-hop configurations sometimes reduce throughput. Streaming platforms and geo-restricted services are supported on many ProtonVPN servers, but results can vary as streaming providers continually update their anti-VPN measures. Conclusion ProtonVPN is a solid choice for privacy-conscious users who want transparent, well-audited software from a company with a strong privacy track record. Its combination of modern protocols, unique privacy features, and multiple plan options make it suitable for both casual users and privacy-focused power users.
