SIGA OT Solutions presentation at the US Midwest TAG 30 showcases our unique approach to securing critical infrastructure by moving beyond traditional network monitoring.  We address the inherent weakness in the Purdue Model: the fact that most security tools rely on digital data that can be manipulated at the PLC level. We demonstrate how our technology provides a “Source of Truth” by tapping directly into Level 0 – the raw electrical signals (I/O) between sensors and actuators.
