ProtonVPN is a privacy-focused virtual private network developed by the team behind Proton Mail. Built with strong principles of user privacy and transparency, ProtonVPN aims to provide secure internet access without logging user activity, all under Swiss jurisdiction—an advantage for users concerned about data protection and government surveillance. Security and privacy ProtonVPN emphasizes security through robust encryption and modern VPN protocols. It supports WireGuard for fast, efficient connections alongside OpenVPN and IKEv2. The service uses AES-256 encryption and key exchange that meet industry best practices. Crucially, ProtonVPN operates a strict no-logs policy: it does not retain browsing activity, connection timestamps, or IP addresses that could identify users. The company has also published transparency reports and undergone independent audits of its apps and infrastructure, reinforcing trust. Unique features One standout feature is Secure Core, which routes traffic through privacy-friendly countries (such as Switzerland and Iceland) before it exits to the public internet. This multi-hop design defends against network-level adversaries and adds a layer of protection for users in high-risk environments. ProtonVPN also offers Tor over VPN — connecting directly to the Tor network through the ProtonVPN app — which makes accessing .onion sites easier and adds privacy for Tor users. Additionally, ProtonVPN provides a built-in kill switch and DNS/leak protection to prevent accidental exposure of your data if the VPN connection drops. Free and paid plans ProtonVPN offers a generous free tier with access to servers in several countries and no data caps — uncommon among free VPNs. Paid plans unlock faster servers, more countries, P2P support, Secure Core, and more simultaneous connections. While ProtonVPN is generally competitively priced, some advanced features are reserved for higher-tier subscriptions. Performance and usability Thanks to WireGuard and well-maintained server infrastructure, ProtonVPN delivers solid speeds suitable for streaming and remote work. It unblocks popular streaming platforms in many regions, though streaming performance can vary by server and licensing restrictions. The apps are open-source and available across major platforms (Windows, macOS, Linux, Android, iOS), and the interface is straightforward for beginners while offering advanced settings for experienced users. Considerations No service is perfect. ProtonVPN’s premium plans can be pricier than some competitors, and peak-time server congestion may affect speeds in certain regions. Additionally, while Secure Core improves privacy, it can reduce throughput because traffic travels through multiple hops. Conclusion ProtonVPN is an excellent choice for users prioritizing privacy and transparency. With strong encryption, modern protocols, a free no-data-cap plan, and privacy-enhancing features like Secure Core and Tor over VPN, it offers a reliable, user-friendly VPN solution for everyday browsing, streaming, and secure remote access.
