March 25, 2026 — The industrial control systems security market will grow from $18.35 billion in 2025 to $20.17 billion in 2026 at a 9.9% CAGR, and is projected to reach $29.21 billion in 2030 at a 9.7% CAGR, according to the ICS Security Market 2026 Report. The growth in the historic period can be attributed to increasing connectivity of industrial control systems, rising cyber incidents targeting critical infrastructure, expansion of remote industrial operations, adoption of legacy scada modernization and growing regulatory scrutiny.
Cyber attacks and the growth of the ICS market
The rising number of cyberattacks on critical infrastructure is expected to propel the growth of the industrial control systems (ICS) security market going forward. Critical infrastructure refers to the systems and assets essential for the functioning of a society and economy, including power grids, water systems, communication networks, transportation systems and financial and government institutions. Because of the critical role these infrastructures play, organizations operating them must implement robust cybersecurity measures to safeguard their systems and assets from increasingly sophisticated cyber threats. This rising threat landscape is accelerating the adoption of industrial control systems (ICS) security solutions. For instance, in October 2024, according to Check Point Software Technologies Ltd., an Israel-based cybersecurity company, cyberattacks in the U.S. increased by 56% year-over-year, with organizations experiencing an average of 1,300 attacks per week — 10% higher than the previous quarter. Therefore, the growing number of cyberattacks on critical infrastructure is driving the demand for ICS security.
Innotive solutions in the ICS market
Innovative solutions have emerged as a major trend in the industrial control systems (ICS) security market. Leading companies are introducing advanced technologies to reinforce their market position and address evolving security requirements. For example, in September 2024, MicroSec, a Singapore-based OT and ICS cybersecurity company, launched CyberAssessor for OT/ICS, an AI-driven automated cybersecurity assessment platform designed specifically for the ISA/IEC 62443 standard. The solution automates cyber-risk and compliance assessments across multiple sites down to individual devices, including third-party hardware and software, and offers a unified dashboard providing real-time visibility into compliance scores, risk levels and recommended actions aligned with IEC 62443 and other frameworks, such as ISO 27400 and CIS benchmarks. It also leverages automated digital questionnaires, real-time network traffic capture, asset discovery and zone mapping to identify both known and unknown systems.
Key companies participating
In September 2025, Mitsubishi Electric Corporation, a Japan-based provider of industrial electronics, acquired Nozomi Networks Inc. for $883 million. Through this acquisition, Mitsubishi Electric aimed to strengthen its industrial cybersecurity business by integrating Nozomi Networks’ AI-powered, cloud-first OT/IoT/CPS security platform to deliver a comprehensive, one-stop OT security solution. Nozomi Networks Inc. is a US-based provider of industrial control systems security solutions.
