Content Filtering
This chapter covers how to use the content filtering feature to control web access.
22.1 Content Filtering Overview
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 filtering policies for different addresses, schedules, users or
groups and content filtering profiles. For example, you 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.
22.2 Content Filtering Policies
A content filtering policy allows you to do the following.
• Use schedule objects to define when to apply a content filtering profile.
• Use address and/or user/group objects to define to whose web access to apply the content
filtering profile.
• Apply a content filtering profile that you have custom-tailored.
22.3 External Web Filtering Service
When you register for and enable the external web filtering service, your ZyWALL accesses
an external database that has millions of web sites categorized based on content. You can have
the ZyWALL block, block and/or log access to web sites based on these categories. The
content filtering lookup process is described below.
