They're stupid expensive, those machines. A lot of places are finding that it's less expensive to maintain an EMSEC zone and run COTS equipment.

I've heard about them being used for an opposite reason. Rather than for security, they are used in places where you don't want to risk them interfering with other equipment, like a room with radar equipment that might be sensitive.
