OT security market projected to quadruple amid rising infrastructure threats

The global operational technology (OT) security market is projected to expand significantly, growing from $44.34 billion in 2025 to an estimated $178.93 billion by 2035. This represents an annual growth rate of nearly 15%, driven by rising cyberattacks against critical infrastructure, industrial control systems, and the rapid adoption of industrial IoT and smart manufacturing.

Recent security incidents have underscored these risks. A critical vulnerability was identified in several Siemens PLC models, potentially allowing unauthorized remote access and manipulation of control systems. Additionally, a ransomware attack recently targeted a water treatment facility in the U.S. Midwest, disrupting operations and exposing sensitive data.

Agencies such as CISA have issued alerts regarding vulnerabilities in industrial automation software that could allow remote code execution. Experts suggest that the increasing use of offensive AI to generate malicious scripts is likely contributing to the speed and sophistication of these attacks. Sectors including power, transportation, energy, and utilities are expected to lead investment in threat detection, monitoring, and incident response technologies.
