Fortiphyd Logic Inc develops secure industrial control system (ICS) networks that protects their productivity, equipment, and personnel threatened by increasingly advanced ICS cyber attacks. One of the firm's primary products, LogicGuard, detects changes made over the network and via the serial port of controllers, protecting against remote and insider attacks and benign incorrect program changes. The company also offers ControlWatch, which uses advanced machine-learning algorithms to detect sophisticated attacks while minimizing false alarms.
