ProtonVPN is a virtual private network service built around privacy, transparency, and strong security. Launched by the team behind Proton Mail, the service emphasizes protecting users’ data from surveillance and network threats while providing practical features for everyday use: secure browsing, streaming, torrenting, and safe public Wi‑Fi access. Privacy and jurisdiction One of ProtonVPN’s key selling points is its Swiss base. Switzerland has robust privacy laws and is outside EU/US intelligence alliances, which can make it harder for foreign governments to compel data disclosure. ProtonVPN operates a strict no-logs policy, meaning it does not record activity or session details that could identify users. The company also publishes transparency reports and has engaged independent auditors to review parts of its infrastructure and apps. Security features ProtonVPN supports modern VPN protocols including WireGuard, OpenVPN, and IKEv2, giving users a balance of speed and security. It uses strong encryption to protect data in transit, and apps include essential safety tools such as a kill switch (to block traffic if the VPN connection drops), DNS leak protection, and IPv6 leak protection. Secure Core and NetShield A distinctive ProtonVPN feature is Secure Core, which routes traffic through privacy-friendly servers in secure locations before it exits to the internet. This defends against network-level attacks and makes it more difficult to trace a connection back to its origin. ProtonVPN also offers NetShield, an optional DNS-based filtering feature that blocks ads, trackers, and known malware domains, improving privacy and reducing exposure to malicious content. Free tier and paid plans ProtonVPN provides a free plan that is notable for having a genuine no-log policy and no data caps, though it is limited to a few server locations and offers lower priority speeds. Paid plans unlock access to high-speed “Plus” servers, Secure Core, Tor over VPN, streaming-optimized servers, and more simultaneous connections. ProtonVPN’s apps are available for Windows, macOS, Linux, Android, iOS, and some routers, with certain features varying by platform (e.g., split tunneling is available on selected clients). Performance and use cases With WireGuard and extensive server coverage, ProtonVPN can deliver competitive speeds suitable for web browsing, HD streaming, and file-sharing. Streaming support and P2P-friendly servers make it a flexible choice for many users. The company’s commitment to open-source clients and external reviews enhances trustworthiness for privacy-minded customers. Conclusion ProtonVPN is a solid option if privacy, transparency, and security are your primary concerns. Its Swiss jurisdiction, no-logs ethos, Secure Core routing, and open-source approach set it apart from many competitors. For casual users, the free tier is an attractive way to get started; power users will find the paid plans offer advanced protections and better performance.
