PFP Cyber does something so new and so positive it almost defies categorization. There is no Gartner magic quadrant or Forrester wave for what they do. The closest category of security solutions might be those of identity management, authentication and authorization but they are doing these things for hardware, not people. PFP can tell, by measuring details of power consumption, what a device is and if it is behaving normally. It can use this capability to identify counterfeit hardware. It can also identify when malicious code has been installed on devices because of changes to the power signature of the device.
For an overview of how they do it, see:
