The operational-technology security market
The market for operational-technology (OT) security — protecting the control systems that run physical plant — is projected to grow from about USD 23.5 billion in 2025 to roughly USD 50.3 billion by 2030, a compound annual growth rate near 16.5%. As factories connect more equipment, securing it has become a core operating cost.

What it means
An OT-security market more than doubling by 2030 reflects a hard reality: every sensor, controller and connected machine added to a plant widens the attack surface. For an operator the message is that the same connectivity that enables predictive maintenance and AI also creates risk, so cybersecurity for control systems is now part of the cost of digitalisation, not an afterthought.
Context
Operational technology covers the industrial control systems — PLCs, SCADA, sensors and actuators — that run physical processes, historically isolated but now increasingly networked. Analyst estimates for the OT-security market vary widely, from around USD 4-5 billion to over USD 24 billion in the same year, depending on how broadly 'OT security' is scoped. The figures here come from one widely cited forecast and should be read as approximate.
How to interpret this data
About the source: This data comes from MarketsandMarkets. Public datasets like this are the foundation of fact-based decision-making in industry. When you see these numbers cited in vendor proposals or consultant reports, remember: the raw data is freely available, and the value is in how you interpret it for your specific plant and situation.
Where this matters: AI agents for industrial maintenance are built on insights like the data shown here. Rather than treat data in isolation, read the deeper guides to see how these trends translate into actionable levers for your plant.
Sector relevance: This dataset is especially relevant to Power Generation, Chemicals. These sectors face the trends and challenges you see in this chart daily — energy cost pressure, the push for decarbonization, adoption of AI and predictive maintenance. Use this data to benchmark your plant against the industry average and identify where you lag or lead.
How to use this data: Take the headline number but look deeper at the chart. Is it growing or shrinking? Which segments or regions drive the trend? Does your plant's data align, or are you an outlier? Outliers are often where the best opportunities hide — either an efficiency gap you can exploit, or a leading practice you can copy.
