You can push internal applications made for the latest Windows Desktop version from AirWatch with the root certificate authority (CA) of your company instead of with a third-party root CA.
Trusted Root CA
Make sure your root CA is part of the trusted root CA list of the device. If it is not trusted, the AirWatch system cannot deploy the application to Windows devices.
The Certificate Authorities (CA) settings page is used to configure integration with various certificate authorities and you can find it at Groups & Settings > All Settings > System > Enterprise Integration > Certificate Authorities .
See Quick Help and select the topic that explains how to integrate your certificate authority and AirWatch.
