US Operational Technology (OT) Security Market

The US operational technology (OT) security market is projected to grow from USD 4.64 billion in 2025 to USD 9.37 billion by 2030, at a CAGR of 15.1% during the forecast period. Growth is driven by increasing cyber risks to critical infrastructure and the growing convergence of IT and OT environments. As industrial systems become more connected, the attack surface across operational environments continues to expand. This is prompting infrastructure operators to strengthen OT security measures, supporting sustained market growth.

The rapid adoption of industrial automation, IIoT, smart manufacturing, and connected production systems has increased the cyber exposure of industrial control systems, utilities, and energy assets. As a result, organizations are increasing their investments in network monitoring, OT asset visibility, managed security services, and compliance-driven protection frameworks. Regulatory oversight across energy, oil & gas, power, transportation, and advanced manufacturing continues to expand as well.
