Understanding the critical role of Trezor Bridge® in your security setup

All data transmitted between your Trezor device and the web interface is encrypted end-to-end, ensuring that even if intercepted, it remains unreadable to attackers.

Automatic Updates

Trezor Bridge® automatically updates to the latest version, ensuring you always have the most secure and compatible communication layer without manual intervention.
