The List Catalog lets you view the types of lists that are used to support the rules of your web policy.

List types include strings, regular expressions, and IP addresses. For example, you can configure a rule that allows all traffic sent from a list of client IP addresses. Lists simplify policy configuration.

You can view and configure lists in the List Catalog, which consists of these list categories.
