SIGA (sigasec.com) is an OT (Operational Technology) cybersecurity company focused on monitoring and protecting industrial control systems and critical infrastructure. The company develops and markets its SIGAGUARD platform, which is designed to detect anomalies in industrial processes by monitoring signals at multiple levels of the OT stack, from Level 0 (physical process signals) through Level 4. This multi-level approach is described as monitoring from the "source," meaning SIGA collects data directly from physical process instrumentation rather than relying solely on network traffic analysis. SIGAGUARD is designed to identify cyberattacks, equipment malfunctions, and operator misuse within industrial environments. The platform incorporates AI-enhanced monitoring to provide operational awareness and process integrity assessment. It is built to operate without disrupting existing Industrial Control Systems and is positioned to require minimal financial and human resources to deploy. SIGA's target market includes industrial operators, commercial facilities, and critical infrastructure operators across sectors such as utilities, energy, and manufacturing. The company has a global partner network spanning multiple continents, with distribution and integration partners in Austria, Germany, Hungary, Italy, Singapore, Spain, the UK, and the United States. The company is headquartered in Israel and positions itself as a specialist in industrial process anomaly detection, with a focus on delivering security visibility at the physical process level—an approach that differentiates it from traditional network-based OT security solutions.
