Overview
OT/ICS/SCADA Security covers the protection of operational technology — the industrial control systems (ICS), SCADA, and connected devices that run factories, utilities, pipelines, and critical infrastructure. It is a distinct, fast-growing security category (separate from IT security) led by OT-security specialists (Dragos, Claroty, Nozomi Networks) addressing the unique constraints of industrial environments.
Demand is driven by the IT/OT convergence exposing once-isolated systems, escalating attacks on critical infrastructure (Colonial Pipeline, utility threats), and regulation (TSA pipeline directives, NERC CIP). It is an emerging, fragmented, strategically critical segment attracting strong venture and strategic investment, as protecting physical infrastructure becomes a national-security priority.
Market snapshot
OT/ICS/SCADA security is an emerging cybersecurity sub-category within software publishing (NAICS 513210) and is not separately disclosed by the Census Bureau, so the segment is not separately sized here.
