Content Filtering
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 addresses, schedules, users or
groups and content filter profiles. For example, you can configure one policy that blocks John

lets him access them after work.

• Use schedule objects to define when to apply a content filter profile.
• Use address and/or user/group objects to define to whose web access to apply the content
filter profile.
• Apply a content filter profile that you have custom-tailored.
