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.
