You can create rules to control access to specific cloud applications. Cloud apps are organized into categories to facilitate defining rules for similar applications.
Additionally, you can define a daily quota by bandwidth or time. When users browse to these sites after their quota has been reached, the Zscaler service displays a message that explains that the content cannot be viewed because they exceeded their daily quota.
To add a rule, you can go to Policy > URL & Cloud App Control and choose a category. See image.
Click on a cloud application category below to learn more about creating rules for the category.
For information on the order in which the service enforces all policies, including this policy, see How does the Zscaler service enforce policies?
