Brief about ADOM
ADOMs (Administrative Domain) enables administrators to manage only those devices that they are specifically assigned. The use of ADOMs allows us to create a separate logical environment, in which we can maintain separate sets of devices. The device may be physical or virtual. Each administrative domain provides isolated management based on geographic responsibilities or any other reason one might need to maintain separate zones of responsibility. The number of ADOMs depends on the Fortimanger platform.
This video showcases the steps to create ADOMs in Fortimanager.
