Kudelski Security MDR For OT is a managed detection and response service designed for operational technology and cyber-physical systems environments. The service provides 24/7 threat monitoring, detection, and response capabilities specifically tailored for industrial control systems, SCADA networks, PLCs, and sensor networks. The service combines the FusionDetect platform with Claroty security technology to deliver continuous monitoring across OT and IT networks. It performs automatic device discovery in OT/IT networks and provides visibility into vulnerabilities across industrial environments. The service includes manual threat hunting capabilities that go beyond standard automated controls. Security analysts operate under strict OT "Rules of Engagement" to maintain operational integrity, working in read-only mode and coordinating with operational teams before taking any action. The service correlates telemetry from Claroty platforms (on-premise CTD or cloud xDome) with log data from OT and IT sources, applying threat intelligence and vulnerability intelligence for detection. The platform maps attacker behavior to MITRE ATT&CK techniques and provides real-time dashboards through a customer portal. Analysts investigate and validate threats, then provide practical remediation guidance with hands-on support for incident response. The service addresses challenges specific to OT environments including legacy systems with insecure protocols, IT-OT network convergence, limited patching capabilities, and operational downtime constraints.
