Application Control

App DB is used by Sensei's Application Control engine to recognize and classify the application that each connection packet carries. The database contains dynamic signatures that indicate to the packet engine how to better classify the connections.

Sunny Valley Networks is always in care of the APP DB.


Applications are classified according to their type and are listed under the App Controls tab. They are displayed in a click-to-open tree-view for easy access.

Searching Applications to Filter#

There are a lot of applications in App controls page, and it can be difficult to scroll down and navigate through all of the individual application categories. You can use the Search field to look for and locate a specific application. To find an application in the list, simply type its name into the search form.
