ProtonVPN is a virtual private network (VPN) service developed by the team behind Proton Mail. Built around privacy and transparency, ProtonVPN aims to give users secure, private access to the internet while minimizing data collection and maximizing auditability. Headquartered in Switzerland, it benefits from strong privacy laws and a jurisdiction outside of EU and US surveillance alliances. Core privacy features define ProtonVPN’s appeal. The service maintains a strict no-logs policy and uses modern VPN protocols including WireGuard, OpenVPN, and IKEv2. WireGuard is often the preferred default because it delivers a good balance of speed and security. ProtonVPN’s Secure Core architecture routes traffic through multiple servers in privacy-friendly countries (such as Switzerland and Iceland) before it exits to the wider internet, making it harder for observers to trace connections back to users. Additional protections include a kill switch that blocks internet access if the VPN connection drops, DNS leak protection, and split tunneling on supported platforms. ProtonVPN also integrates with the Tor network: users can connect directly to Tor over VPN servers to access .onion sites without using a separate Tor Browser, though this is generally slower and intended for specific privacy needs. The company publishes transparency reports and has undergone independent security audits; its desktop and mobile apps are open-source, allowing external verification of their implementations. Performance and usability have improved over time. ProtonVPN operates a global server network with options optimized for streaming, secure core, or P2P/torrenting. WireGuard support typically yields fast throughput suitable for HD streaming and large downloads. However, speeds can vary with server load and geographic distance. ProtonVPN offers dedicated streaming servers that can help access region-locked services, though success with specific platforms can change as streaming providers update their detection measures. Plans range from a free tier—limited in speed and available countries but useful for basic encrypted browsing—to paid tiers with higher speeds, more simultaneous connections, and access to Secure Core, advanced servers, and additional features. Business and family plans are available too. The paid tiers are pricier than some budget competitors, but many users find the privacy-oriented features and Swiss jurisdiction justify the cost. Apps are available for Windows, macOS, Linux, Android, and iOS, with browser extensions for quick connections. Customer support includes documentation, email support, and community resources. In summary, ProtonVPN is a solid choice for users who prioritize privacy, transparency, and jurisdictional protection. It combines strong technical features with an ethical, audit-friendly approach, making it especially appealing to privacy-conscious individuals and journalists. Trade-offs include potential cost and occasional speed variability, but overall it remains a trusted and reputable VPN provider.
