Europe Operational Technology (OT) Security Market

The Europe operational technology (OT) security market is projected to grow from USD 5.70 billion in 2025 to USD 11.93 billion by 2030, at a CAGR of 15.9%. Market growth is driven by rising cyber threats to critical infrastructure and increasing regulatory pressure across European countries. The convergence of IT and OT environments is expanding the attack surface, prompting industrial operators to enhance their OT security controls.

The growing adoption of industrial automation, IIoT, smart manufacturing, and connected production systems has increased cyber exposure across energy, utilities, manufacturing, and transportation sectors. As a result, organizations are increasingly investing in OT visibility, network monitoring, managed security services, and compliance-focused protection frameworks. Regulatory initiatives such as NIS2, along with ongoing infrastructure modernization, continue to support sustained demand for OT security solutions and services across Europe.
