Opswat MetaDefender OT Security

MetaDefender OT Security is an OT security platform that discovers PLCs, HMIs, engineering workstations and other OT assets on industrial networks using passive or safe methods, and monitors their communications and risks. It centrally provides asset inventory, network visibility, vulnerability and patch information, configuration change tracking, threat detection and compliance reporting.

Knowing which devices are on the production network and what normal communication between them looks like means unexpected connections or changes are noticed early. Security teams can prioritize risks without disrupting operations and make exposure from legacy systems and missing patches visible. Central inventory and reports support compliance with frameworks such as IEC 62443 while establishing a shared language of risk between OT and IT teams.
