Apple helps companies deploy and configure their devices through the Device Enrollment Program (DEP). The program enables automatic registration, configuration and monitoring of Apple devices during setup through a Device Management Solution (MDM) - without the need for setup service or physical access to the device. DEP also allows Apple devices to operate in supervised mode, allowing certain configuration restrictions such as turning off iMessage or Game Center to be centrally stored. For this purpose, a DEP server is defined in the MDM, which identifies itself via an Apple certificate. The corresponding feature for Android is Zero Touch Enrollment.
