SIGA OT Solutions takes a different approach from network-based OT security. Its SigaGuard appliance taps the raw analogue and digital signals between field devices and programmable logic controllers, then uses machine learning to detect deviations that indicate a cyber attack or equipment fault, even if the controller itself has been compromised. The company serves water utilities, power generation and industrial plants and has partnerships with system integrators in the United States and Europe.
