Driver: More cyberattacks on US critical infrastructure as IT-OT converge
In the US, there is an increase in attack surface across power grids, pipelines, transportation systems, and manufacturing plants due to the growing convergence of IT and OT environments. Cyberattacks such as ransomware, nation-state intrusions, and supply chain threats are becoming more frequent. These risks are pushing organizations to adopt OT focused security, stronger network segmentation, and continuous monitoring to protect essential industrial operations.
Restraint: High upgrade costs for legacy OT systems
Many US industry sites still use decades-old OT equipment with limited security features is still being used. Upgrading controllers, networks, and monitoring systems often requires high capital investment and planned downtime. These upgrades also demand specialized skills, creating financial and operational pressure. As a result, some organizations delay security modernization and continue operating with limited visibility and protection.
Opportunity: Expanding ICS-security demand across major US industries
Investment in OT cybersecurity is rising across power utilities, oil and gas operations, transportation networks, water facilities, and manufacturing plants as security requirements increase. Regulatory pressure, digital modernization, and automation are raising security expectations. This is creating demand for protocol-aware monitoring, Zero Trust-based OT security, and AI-enabled anomaly detection, opening growth opportunities for industrial security solution providers.
Challenge: Vendor and supply chain exposure
Vendor and supply chain exposure increases risk across US industrial environments. Third-party software, remote service providers, and embedded components introduce indirect entry points into OT networks. Limited visibility into vendor security practices and update cycles complicates risk management, pushing operators to strengthen access controls, monitoring, and third-party security oversight across ICS environments.

Market Definition
According to Forcepoint, industrial control systems can consist of a complex network of interactive control systems or a small number of controllers. These systems receive information from remote sensors that measure and monitor process variables. From control valves to pressure gauges, an ICS sends commands and receives alerts from many different components. ICS security is a security framework that protects these systems against accidental or intentional breaches and risks.
ICS security solutions consist of a comprehensive array of technologies such as Distributed Denial of Service (DDoS), Intrusion Detection and Prevention System (IDPS), anti-malware/antivirus, firewall, virtualization security, Security Information and Event Management (SIEM), SCADA encryption, Unified Threat Management (UTM), Data Loss Prevention (DLP), and Identity and Access Management (IAM).
