FortiManager appliances scale to manage thousands of Fortinet devices and agents. Administrative domains (ADOMs) enable administrators to manage only those devices that are specific to their geographic location or business division. FortiGate devices with multiple VDOMs can be divided among multiple ADOMs.

If ADOMs are enabled, each administrator account is tied to an ADOM. When a particular administrator logs in, they see only those devices or VDOMs that have been enabled for their account. Administrator accounts that have special permissions, such as the admin account, can see and maintain all ADOMs and the devices within those domains.

ADOMs are not enabled by default, and enabling and configuring the domains can only be performed by the admin administrator. For more information, see “Enabling and disabling the ADOM feature”.

The default and maximum number of ADOMs you can add depends on the FortiManager system model and the available ADOM license key. Please refer to the FortiManager datasheet for information on the maximum number of devices and agents your model supports. You can contact your local Fortinet reseller to purchase an ADOM licence to increase the number of device ADOMs.
