Registration
The FortiGate, and then its service contract, must be registered to have full access to Fortinet Customer Service and Support, and FortiGuard services. The FortiGate can be registered in either the FortiGate GUI or the FortiCloud support portal. The service contract can be registered from the FortiCloud support portal.
To verify the license status on the FortiGate, go to System > FortiGuard and check the License Information table. There can be a delay of a few hours between when you register your device and when the license information on the FortiGate is updated.
The License Information table can be used to confirm that the FortiGate is receiving the latest updates. Expand a service in the table and hover over a version to see the day it was last updated. Some services have daily updates, but others will remain unchanged for a longer period of time. For example, the AV engine can stay unchanged for months, while the AV signature database can receive multiple updates a day.
If you are not receiving updates, ensure that the FortiGate's communication with FortiGuard is uninterrupted (see the FortiOS Ports guide), and check the FortiGuard troubleshooting section in the FortiOS Administration Guide.
