Applying ACL rules

ACL rules apply to all
CylanceGATEWAY
users in the tenant. ACL rules evaluate each network access attempt in the order that they are displayed in the management console, from the top down. The default rule will always be evaluated last, and if none of the previous rules match will block access to all resources. The Default rule cannot be disabled or modified
When you create the ACL rules, BlackBerry recommends that you create your ACL rules and make sure that they are displayed in the in following order:
  1. Block access to Internet content that contains
    CylanceGATEWAY
    specified categories
  2. Block access to non-categorized services based on your organization's requirements
  3. Allow access to organization-wide services in the private network
  4. Allow access to all public Internet destinations
  5. Default
The following table provides examples of rules and their necessary settings:
