Cisco IronPort Web Usage Controls includes the Application Visibility and Control engine (AVC
engine) which enables administrators to apply deeper controls to particular application types. The AVC

having to fully understand the underlying technology of each application.
Application control gives you visibility and control over the following types of applications:
•
Evasive applications, such as anonymizers and encrypted tunnels.
•
Collaboration applications, such as Cisco Webex and instant messaging.
•
Resource intensive applications, such as streaming media.
To control applications using the AVC engine, perform the following steps:
