EXO5 allows enterprises to track and remote kill corporate laptops. It's available as a cloud service. They only serve the enterprise market and have a minimum order of 25 devices. List price is $29 per device per year. The administration console can manage large numbers of devices and manage them by policy. They offer more of the business-level features such as tracking, disk encryption and device tracking, and don't include consumer-level features like webcam snooping and keyloggers. They seem to have taken off in recent years, with lots of customers in high-security industries like financial services and healthcare.
