OT Security Tools FAQ
Common questions about OT Security tools, selection guides, pricing, and comparisons.
OT environments run industrial protocols (Modbus, DNP3, OPC-UA) that IT security tools do not understand. Active scanning can crash safety-critical PLCs and SCADA systems. OT networks require passive monitoring that does not inject packets, asset discovery that understands industrial device types, and security policies that prioritize safety and availability over confidentiality. IT tools designed for TCP/IP traffic will miss OT-specific threats and potentially cause outages.
The Purdue Model defines network segmentation layers for industrial environments, from Level 0 (physical processes and sensors) through Level 5 (enterprise network). Proper segmentation according to this model prevents attackers who compromise the IT network from reaching safety-critical industrial systems. OT security tools help enforce and monitor these boundaries.
OT asset discovery tools use passive network monitoring to identify devices by analyzing industrial protocol traffic without sending any packets. They parse protocols like Modbus, EtherNet/IP, and Profinet to identify device types, firmware versions, and communication patterns. Some also integrate with historian databases and engineering workstations to enrich asset inventories.
