 ### AdGuard VPN protocol
 
-By default, AdGuard VPN protocol uses dynamic VPN protocol selection (*Auto-select* option). That means that AdGuard VPN automatically figures out which protocol — HTTP2/TLS or HTTP3/QUIC — will give you the best performance and switches to it instantly. This improves VPN speed and stability, which is particularly helpful in regions where VPN usage is restricted or unreliable.
-
-If you know what you are doing, you can switch AdGuard VPN to use only HTTP2/TLS or HTTP3/QUIC protocol instead of *Auto-select*. [QUIC](https://adguard-vpn.com/kb/general/why-adguard-vpn/#6-quic-support) is a relatively new protocol, hence it can be less stable. However, if your Internet connection is unstable (for example, when you connect to the public Wi-Fi), it provides better security and increases the connection speed thanks to the [Head-Of-Line Blocking](https://adguard-dns.io/en/blog/dns-over-quic.html#headoflineblocking) technology.

-Also, here’s a dedicated article about the protocol: [How AdGuard VPN protocol works](/general/adguard-vpn-protocol.md).
+AdGuard VPN uses TrustTunnel — a modern, open-source VPN protocol developed by us and available for anyone to use, audit, and implement. [Visit the website](https://trusttunnel.org/) to learn how it works and why it’s different from traditional VPN protocols.

 - Masks your IP address. Your true IP address is the key to your personal data for cybercriminals. Your name, email address, phone number, credit card information can all fall into the hands of fraudsters if you don’t hide your IP. With AdGuard VPN, all your traffic goes through an encrypted tunnel and comes to the VPN server. The web server registers the IP address of the endpoint of the tunnel, i.e. the VPN server, and not the device’s real IP address.
