Security License
The security services are licensable. The security license is valid for one year or
three years depending on the bundle type. By default, the security appliance
comes with a one year bundle license for all security services. To renew the
security license before it expires, go to the
Device Management ->

For example, a website is permitted by the Web URL Filter setting, but it has
reputation score lower than the web reputation threshold, the connection to this
website will be blocked even if it is in the whitelist, unless you change the web
reputation threshold.
