New Feature: Rich Acceptable Use Controls with URL Filtering
AsyncOS for Web 6.3 introduces a new platform, Cisco IronPort Web Usage Controls, for rich
acceptable use controls to address the challenge of current day Web traffic. The new platform
includes a new and improved URL filtering engine with dynamic categorization capabilities
for the uncategorized traffic. Subsequent releases will build on this new platform to include
additional capabilities for application control and bandwidth management.

Cisco IronPort Web Usage Controls includes the Dynamic Content Analysis engine, a highly
sophisticated technology on the appliance for real-time analysis of uncategorized sites. This
engine improves URL filtering by categorizing some of the uncategorized traffic in real-time,
and is especially effective for commonly blocked categories containing objectionable
content. This addresses the challenge posed by thousands of sites being added to the Web
every few minutes. URL databases have difficulty keeping up with this volume and they take
time to update.

The new URL filtering engine has more granular categories. Efficacy for the new URL filtering
engine is supported by a combination of sophisticated backend tools, processes, and a global
team of categorization experts to provide continuous automatic updates to the URL database
on customers’ Web Security appliances. This also results in a huge improvement in our
responsiveness for categorization or re-categorization requests.
