According to Straits Research, the global industrial control systems (ICS) security market size was valued at $18.93 billion in 2025 and is projected to grow from $20.24 billion in 2026 to $34.51 billion by 2034, at a CAGR of 6.9% during the forecast period 2026–2034.
An industrial control system (ICS) comprises various control elements, including electrical, mechanical, hydraulic, and pneumatic components. The control element of the system includes the specification of the anticipated output or performance. Control can either be fully automated or include a human. In addition, the systems can be configured to operate manually, closed-loop, or open-loop.
OT asset targeting occurred more frequently in 2019 than combined in the preceding three years. Most of these targets combined known vulnerabilities in ICS hardware components and supervisory control and data acquisition systems with brute-force login methods, such as password-spraying attacks (SCADA). Metallurgical company Norsk Hydro had to stop operations for a week due to a ransomware attack (LockerGoga encrypts files on Windows devices). The attack encrypted all the data on their Windows machines. Nearly 70% of firms think an attack on their OT/ICS infrastructure is very likely, according to a 2019 ARC Advisory Group survey on the security of industrial control systems (ICS). Similar conclusions came from research conducted by the Ponemon Institute and Siemens. The growing incidents of cyberattacks are expected to drive the global industrial control systems (ICS) security market over the forecast period.
The convergence of information technology and operational technology refers to the integration of OT systems, which are typically used in manufacturing and industrial environments and used to monitor processes, events, and devices and make adjustments in business and industrial operations using ICS, such as supervisory control and data acquisition (SCADA). Industrial enterprises are integrating their IT and OT networks to stay competitive and improve business decisions. The fusion of IT and OT enables more accurate control and extensive monitoring. Due to the growing number of industrial control systems, sensors, and other controllers acting as Industrial Internet of Things (IIoT) endpoints due to the converged IT/OT network, organizations are more vulnerable to cyberattacks and security threats.
North America is the most significant shareholder in the global industrial control systems (ICS) security market and is expected to grow at a CAGR of 6.7% during the forecast period. Data has been produced while integrated with a wide range of production systems throughout the supply chain due to the region's vast manufacturing. This is illustrated by a report from the Department of Homeland Security from February 2020 that listed 16 infrastructure sectors as essential, including the energy, nuclear, and transportation sectors. A warning about a hack that targeted a pipeline operator last year prompted this action. The recent advancements have put an even greater emphasis on how critical it is to protect ICS systems. The country has significantly benefited from this in terms of establishing a competitive edge in the global economy.
Asia-Pacific is expected to grow at a CAGR of 6.8%, generating USD 7,200.62 million during the forecast period. The rapid development of industrial infrastructure, the increasing investment in industrial security infrastructure, and the widespread adoption of cutting-edge technologies like IoT and cloud computing all point to Asia-Pacific as the region with the highest CAGR over the forecast period.
