An example of a first computing device may include firmware, a controller, and a processor. The processor may be to generate a trust state message, to be sent to the controller, indicating the firmware of the first computing device is operating a trusted environment and utilize the firmware to validate an update within the trusted environment. The controller may be to assert, responsive to receiving the trust state message, a trust state signal to a second computing device indicating the firmware of the first computing device is operating the trusted environment The assertion of the trust state signal may be to enable the second computing device to install the validated update.
