Applications

(To download, install, or remove applications, go here).

There are two types of Applications:

• Filter Applications: All the Applications above the Services pane in the interface can have unique configurations, which you can apply to specific virtual racks. Virtual racks enable you to create different policies for different sets of users.
• Service Applications: All the Applications below the Services pane are services and are "global." Each has a configuration that applies to all virtual racks. As such, if you remove any service from any rack, you will remove that service from all racks.
