The global operational technology market size was valued at USD 210.06 billion in 2024 and is projected to reach USD 364.74 billion by 2030, expanding at a CAGR of 9.6% from 2025 to 2030. The Operational Technology (OT) industry plays a critical role in managing essential infrastructure such as power grids, water treatment facilities, and manufacturing plants, which is fueling its rapid growth.

The market expansion is largely driven by the growing adoption of Industry 4.0, which integrates advanced technologies like AI, IoT, and big data analytics. These technologies require real-time data collection and analysis, a core capability of OT systems. Additionally, the increasing focus on industrial automation to improve efficiency and ensure workplace safety is accelerating the demand for OT solutions.

As industrial control systems become increasingly complex, there is a rising need for secure and reliable OT systems to maintain operational continuity and prevent disruptions. For example, in July 2023, Stellar Cyber introduced XDR for OT environments, an enhancement to its Open XDR Platform. This feature enables organizations to detect, analyze, and respond to threats across IT and OT networks through OT-specific threat detection rules, visibility into OT devices, and automated as well as manual remediation actions. Such innovations are crucial for protecting interconnected IT and OT ecosystems from evolving cyber threats.

The increasing integration of digital technologies in industrial processes has intensified the demand for OT security solutions. These solutions safeguard industrial control systems from unauthorized access and potential damage. As OT systems become more connected with IT networks, the threat landscape grows more sophisticated, making OT security essential for preventing cyberattacks and ensuring the reliability of critical operations like power generation, manufacturing, and water treatment.

The COVID-19 pandemic further boosted the OT market by accelerating the need for remote monitoring and control systems. Organizations adopted remote solutions to monitor OT systems globally, increasing reliance on digital transformation. Furthermore, heightened awareness about OT security during the pandemic resulted in greater investments in cybersecurity measures.
