How a VPN works

A VPN (Virtual Private Network) creates an encrypted tunnel between your device and a VPN server. All your internet traffic is routed through this tunnel. Websites see the VPN server's IP address instead of your real IP, and your ISP can only see that you are connected to a VPN – not what you are doing.

VPN leaks – check yours

Even with a VPN enabled, your real IP can leak through WebRTC or DNS. Use our tools to verify your VPN is working correctly:

VPN – privacy tool with limitations

A VPN hides your IP address and encrypts your internet traffic, providing privacy from your ISP and anonymity from websites. However, a VPN is not a complete privacy solution – it does not protect against cookies, browser fingerprinting or malware. WebRTC and DNS leaks can expose your real IP even with a VPN active. Always test your VPN with leak tests to ensure it is working correctly.
