ProtonVPN is a virtual private network (VPN) service developed by Proton AG, the Swiss company known for ProtonMail. Built around privacy-first principles, ProtonVPN aims to give users control over their online data by encrypting internet traffic, hiding IP addresses, and offering features designed to resist surveillance and tracking. At its core, ProtonVPN provides standard VPN protections: encrypted tunnels that prevent local networks and ISPs from seeing the contents of your traffic, and IP address masking that helps reduce tracking and geolocation-based restrictions. ProtonVPN supports modern protocols including WireGuard, OpenVPN, and IKEv2, allowing users to balance speed and security according to their needs. WireGuard is often recommended for the best combination of performance and security. A standout feature is Secure Core, ProtonVPN’s multi-hop architecture that routes traffic through privacy-friendly countries (like Switzerland and Iceland) before reaching the public internet. This adds an extra layer of protection against network-level adversaries and reduces the risk of IP-based correlation. ProtonVPN also offers a Tor over VPN option that routes selected traffic through the Tor network, making it easier to access .onion sites without configuring a separate Tor browser. Privacy and transparency are central to ProtonVPN’s approach. The company is headquartered in Switzerland, a jurisdiction with strong privacy laws, and maintains a no-logs policy. Proton’s apps are open-source, and the service has undergone independent security audits, increasing trust in their claims. ProtonVPN bundles practical features for everyday use: a kill switch to block traffic if the VPN disconnects, DNS leak protection, split tunneling on supported platforms, and NetShield — an integrated ad, tracker, and malware blocker available on paid plans. The provider supports P2P traffic on designated servers and can help bypass geo-restrictions for many streaming services, though streaming performance can depend on server selection and legal restrictions. Getting started with ProtonVPN is straightforward: create an account on the Proton website, choose between a free tier or paid plan, download the client for Windows, macOS, Linux, Android, or iOS, and connect to a server. For best speed, pick a nearby server or use WireGuard; for maximum privacy, enable Secure Core. Keep clients updated and enable the kill switch when using untrusted networks. No service is perfect: free plans have limited servers and speeds, advanced features require paid subscriptions, and occasional regional blocking or speed variability can occur depending on network conditions. Users should also be aware of local laws regarding VPN use. In summary, ProtonVPN is a solid choice for privacy-conscious users who want a transparent, well-supported VPN with strong technical features. Its combination of modern encryption, multi-hop routing, Tor integration, and open-source clients make it especially appealing to those who prioritize security and trustworthiness in a VPN provider.
