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.
AsyncOS for Web offers the following features to filter adult content:
•
Enforce safe searches. Most search engines allow the safe search feature to be
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.

for streaming media applications. You can define an overall bandwidth limit and per
