Sensei's Application Control engine uses "App DB" to understand and classify the application a particular connection packets carry. The database contains dynamic signatures which hint the packet engine to be able to classify the connections more accurately.
Applications are categorized by their type and listed in a click-to-open tree-view for convenient access.
You can use dynamic search on top of the category list to filter out the items. We search as you type.
Sensei allows you to block individual applications by clicking on the green check icons located on the left side of each application.
You can also block the entire category by clicking the green check icon located on the left side of the category name.
When you're ok with the changes you made, click on the button lower right corner of the screen to save and activate the rules.
The rules go in the action immediately after you hit the save button. The request silently blackholed on the user's end.
