URL category database includes the built-in URL database and custom URL database. The built-in URL database is updated regularly by the device. Such updates require an S/N license, and the device must be able to access the Internet. The custom URL database can be added, deleted, and modified.

Navigate to Objects > Content Identification Database > URL Category. On the URL Category page, you can view the release date and time of the current version of the built-in URL category database and the expiry date of the built-in URL update. See the figure below.
