SIGA develops and markets cybersecurity solutions for industrial control systems and supervisory control and data acquisition systems used in critical infrastructure and industrial processes. Its proprietary, device-based solution provides early warning in the event of an anomaly, whether caused by cyberattack or system malfunction.

SIGAs product, which is based on machine learning algorithms and electrical engineering, uses hardware that is connected to the SCADA system after the PLC and before the real-world device it controls. The proprietary software is installed on a server at the customers location, in complete isolation from externally connected networks.

SIGA was named a cool vendor in Cool Vendors in Industrial IoT and OT Security, 2018 by the Gartner Research Group.
