What’s New in Version 7.0
New Feature: Safe Search and Site Content Rating Enforcement
AsyncOS for Web 7.0 uses the AVC engine 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.
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.

New Feature: Bandwidth Control for Streaming Media
AsyncOS for Web 7.0 uses the AVC engine to control the amount of bandwidth
used for streaming media applications. You can define an overall bandwidth limit
and per user bandwidth limits. When both the overall limit and user limit applies
to a transaction, the most restrictive option applies.
