The Menu gives you access to AirDefense features.
Features such as Add Devices and Import/Discover Devices are features that are an integral part of AirDefense. Reports and Help are web-based applications. Most of the rest of the features are Java applets. To run the Java applets, you are required to install the AirDefense Toolkit on your local workstation. (If you have no need to run the applets, there is no need to install these AirDefense Toolkit.)
