ICS Security Market Expected to Reach $38.48 Billion by 2031
The global industrial control system (ICS) security market is projected to more than double by 2031 as organisations increase investment in cyber protection for operational technology, critical infrastructure and industrial IoT environments.
According to a recent MarketsandMarkets report, the global ICS security market is expected to grow from USD 17.91 billion in 2026 to USD 38.48 billion by 2031, representing a compound annual growth rate (CAGR) of 16.5% over the forecast period.
The growth is largely being driven by the increasing number and complexity of cyber threats targeting industrial environments. Organisations are therefore investing in advanced security technologies capable of providing real-time threat detection, automated response, and improved risk management across operational and cloud-based infrastructures. At the same time, stricter regulatory requirements and data protection standards are encouraging companies to strengthen compliance measures and improve control over sensitive data in hybrid and multi-cloud environments.
Demand Rising for Professional Cyber Security Services
The report highlights strong growth within the professional services segment, as industrial organisations continue seeking specialised expertise to protect operational technology (OT) systems and maintain resilience across critical infrastructure sectors.
Services such as consulting, system integration, compliance management, training, maintenance, risk assessment, and incident response are becoming increasingly important in helping organisations manage evolving cyber threats. The expansion of industrial automation, connected OT systems, remote operations, and Industrial IoT technologies is also increasing demand for external cyber security specialists capable of securing complex industrial environments without interrupting daily operations.
Oil & Gas Sector Among Fastest-Growing Segments
According to the study, the oil & gas industry is expected to record particularly strong growth within the ICS security market. Increasing digitalisation across upstream, midstream, and downstream operations is expanding the cyber attack surface of critical energy infrastructure.
Operators are deploying OT security solutions to protect drilling operations, pipelines, refineries, storage sites, and remote assets against ransomware attacks, operational disruptions, and cyber-physical threats. Wider adoption of connected sensors, industrial IoT devices, wireless communications, and predictive maintenance systems is further increasing demand for industrial threat detection, OT visibility, and secure remote access technologies.
Major Industry Players
The report identifies several key companies active in the ICS security market, including Cisco, Fortinet, Palo Alto Networks, Tenable, Honeywell, Check Point Software, ABB, Belden, Kaspersky, Darktrace, Radiflow, and Dragos.
