ADOM and policy layer
The ADOM layer is where FortiManager manages individual devices, VDOMs, or groups of devices. It is inside this layer where policy packages and folders are created, managed, and installed on managed devices. Multiple policy packages and folders can be created here. The ADOM layer contains one common object database per ADOM, which contains information such as addresses, services, antivirus and attack definitions, and web filtering and email filter.
