MetaDefender OT Security is an AI-powered OT asset and network security product. It discovers devices passively, builds an asset inventory, maps network connectivity, monitors traffic for threats and anomalies, and assesses ICS vulnerabilities. It integrates with industrial firewalls, intrusion prevention and network access control systems for defense in depth without major infrastructure changes.

• Asset discovery: finds devices and builds an asset inventory, with passive discovery exclusions.
• Network map: visualizes connectivity, links and sessions between assets.
• Threat and anomaly monitoring: continuous alerts, including critical command detection and duplicate identifier detection.
• Alert workflow: policy to alert to incident to response, mapped to MITRE ATT&CK techniques.
• Vulnerability assessment: evaluates ICS vulnerabilities and risks.
• AI queries: natural-language questions about device and asset data (version 3.5.0).

A manufacturing group in Vietnam could deploy sensors across plants to inventory PLCs and detect unauthorized devices. A power utility could ingest substation configuration data and monitor IEC 61850 networks.

Gives OT teams asset visibility and a network map without specialized training. Detects threats, anomalies and abnormal critical commands sent to ICS devices. Reduces manual compliance work and supports defense in depth with existing firewalls and NAC. Designed for large-scale enterprise deployment and installs out of the box.

IT/OT convergence, limited asset visibility, manual compliance work and a shortage of skilled OT security staff are the problems the product targets. Vietnam hosts OPSWAT R&D and an office, and manufacturers and utilities there face the same convergence risks.
