Driver: Increasing cyber incidents impacting ICS, pipelines, substations, and critical utilities
The US OT security market is accelerating as cyber incidents increasingly target ICS networks, pipelines, substations, and utility operations. The rise in OT-focused ransomware, supply-chain attacks, and nation-state activity is pushing operators to invest in asset visibility, anomaly detection, and incident-response capabilities to maintain operational continuity.
Restraint: Cost and complexity of securing legacy control systems and field devices
Securing OT environments remains challenging due to the high cost and technical complexity of protecting legacy control systems, field devices, and proprietary industrial protocols. Integration challenges, limited patching options, and downtime risks continue to slow modernization efforts despite growing exposure to operational threats.
Opportunity: Rising federal and state investments in industrial resilience and critical-infrastructure upgrades
Federal and state programs focused on industrial resilience, grid modernization, and water-system upgrades are driving demand for OT security solutions. Funding from agencies such as CISA and DOE is supporting investments in OT monitoring, secure remote operations, and unified security platforms to improve safety and regulatory compliance.
Challenge: Difficulty integrating heterogeneous PLCs, SCADA, safety systems, and vendor-specific assets
OT environments often include a wide mix of PLCs, SCADA systems, safety controllers, and vendor-specific devices developed over decades. Differences in protocols, limited device visibility, and integration constraints make consistent monitoring and policy enforcement difficult across distributed industrial networks.
