Once ACS identifies a valid threat, administrators can use the softwares containment feature to lock down the airwaves. Airespace access points identify the clients involved and bombard them with signals to drop the radio connection, making it quite difficult to maintain state.

We found this feature to be very effective in tests, depending on the client hardware and drivers. Airespace constantly updates the containment feature to deal with new products and driver revisions, company officials said.

The handy Client Watch List feature allowed us to track and monitor specific users or hardware devices over time, sending alerts or traps if the client performance fell below a configurable threshold.

By default, ACS tracks clients and rogues by identifying the closest access point. Companies that need more accurate measurements can purchase the optional $4,000 advanced tracking module with RF fingerprinting. (We did not test this module.)
