Filtering Adult Content
You can configure the Web Security appliance to filter adult content from some
web searches and websites. You might want to do this to allow access to these
sites, such as google.com and youtube.com, while still restricting potentially
unsafe content from reaching users. For example, a school district could allow
access to educational videos on youtube.com, but block inappropriate contents for
students.

AsyncOS for Web offers the following features to filter adult content:
•
Enforce safe searches. Many search engines support a filtering technology
feature that classifies inappropriate content on the web as adult. When this
filtering feature is enabled, content classified as adult is filtered from the
search results before presented to the user. This feature is commonly called
safe search. However, for most search engines, this feature is enabled and
disabled by end users. You can configure the Web Security appliance so that
outgoing search requests appear to search engines as safe search requests.
This gives the control to an administrator on the network instead of the end
user. You might want to do this to prevent users from bypassing acceptable
use policies using search engines.

Enforce site content ratings. Many content sharing sites that serve
user-generated photos and videos classify some of their content as adult.They
allow users to restrict their own access to the adult content on these sites by
either enforcing their own safe search feature or blocking access to adult
content, or both. This classification feature is commonly called content
ratings.

You enforce safe searches and site content ratings for different users by enabling
the feature at the Access Policy level. Not all search engines or content sharing
websites are supported, but AsyncOS for Web can support additional search
engines and websites during URL filtering engine updates. The Access Policies >
URL Filtering > policyname page always lists the currently supported search
engines and websites for each feature. The list of supported search engines and
content sharing websites may increase with AVC engine updates.
