Definition
Cybersecurity for operational technology and industrial control systems
Technologies
Passive network monitoring detects threats without disrupting OT processes. Asset discovery identifies all connected OT devices and their vulnerabilities. Anomaly detection identifies unusual behavior in industrial control systems. Secure remote access enables vendors and engineers to access OT systems safely. OT-specific threat intelligence provides relevant indicators for industrial threats.
Applications
Passive monitoring detects unauthorized changes to PLC programming. Asset inventory identifies all connected devices in an industrial network. Anomaly detection spots unusual communication patterns between control systems. Secure remote access enables vendor maintenance without network exposure.
Market and funding
The OT security market exceeded $3 billion in 2025, driven by the convergence of IT and OT networks and the growing threat of nation-state attacks on critical infrastructure.
