With your Device Management Account, you get an overview of all the clients and their devices that you have permission to manage. This can be in two formats currently:

The Map View
Here you get a map centered on the main area of the clients you manage. The pins that show are the client locations based on what they/or you have entered into their account profiles. Select the pin to see the related devices. The pin colors also represent the status of the devices in those client accounts. There is a legend at the bottom of the map view to see what the colors represent.
