Content filtering allows you to block certain web features, such as cookies, and/or
block access to specific web sites. It can also block access to specific categories of
web site content. You can create different content filter policies for different

can configure one policy that blocks John Doe’s access to arts and entertainment
web pages during the workday and another policy that lets him access them after
work.
