AI-enabled industrial threats are a significant factor driving the growth of the US ICS security market. Attackers now use automated tools to scan OT networks and identify protocol vulnerabilities and system misconfigurations very quickly. This speed of attack reduces the effectiveness of traditional security controls. As a result, operators are adopting advanced threat detection, behavioral analysis, and continuous monitoring to manage machine-driven attacks.The US power sector is seeing strong growth in ICS security as utilities modernize substations while expanding renewable energy assets and digitizing transmission and distribution networks. Increased remote connectivity across the grid has raised the need for OT level monitoring and secure access controls. These measures help protect against nation-state threats targeting US electric infrastructure. The shift toward distributed energy resources, microgrids, and remote engineering access increases exposure across aging assets. This is pushing utilities to improve vulnerability management, strengthen anomaly detection, and secure engineering workstations, which keeps the power segment as the fastest expanding vertical in the US ICS security market.
By offering, the solution segment is estimated to account for the largest market share during the forecast period.
The US ICS security market covers a broad set of solutions designed to protect operational environments across power, utilities, oil and gas, manufacturing, and transportation. Antimalware and antivirus tools protect engineering workstations and HMIs. Subsequently, DDoS protection helps prevent service disruption across externally connected control networks. Encryption is increasingly being used to secure data flows across substations and remote assets. Firewalls and IDS IPS systems remain core components that support segmentation and monitoring of industrial protocols. IAM solutions help reduce credential misuse and manage remote vendor access, while security and vulnerability management tools identify OT specific gaps across legacy devices. Security configuration management supports control system hardening, and SIEM platforms integrate OT telemetry into enterprise SOC workflows. Allowlisting and specialized tools such as honeypots and deception platforms add protection against targeted intrusions, creating a comprehensive defense environment for US industrial operators.
