Hey, Thanks for reaching out to us.

Hexnode system agent app can grant permissions to the Hexnode MDM app in the device when new versions get released. This avoids the trouble of manually downloading and re-signing the app every single time.
In case of Hexnode MDM’s ROM enrollment, the Hexnode app has to be resigned by the vendor for every update. The system agent app eliminates this.
The Hexnode system agent app also offers extra privileges such as silent app installation, app uninstallation, remote reboot, power off, update OS, etc..

Kindly use the help link to know more about Hexnode System Agent app.

Cheers!
