OPSWAT MetaDefender OT Security: Seeing What Is on the Industrial Network
2 November 2026


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. A device you do not know about on the production network cannot be protected; the first step in OT security is always visibility.
Core Capabilities
Asset inventory: Devices on the production network and the normal communication between them become visible, so unexpected connections are spotted early.
Vulnerability and change tracking: Exposures from legacy systems and missing patches, and configuration changes, become visible.
Compliance reporting: Central inventory and reports support alignment with frameworks such as IEC 62443.
Benefits for Organisations
Security teams prioritise risks without interrupting operations, and OT and IT teams build a common risk language by looking at the same data.
