Unifying Operational Technology Security Monitoring

This case study details the implementation of a centralized monitoring solution for operational technology (OT) security by a global industrial manufacturer. The organization faced challenges with fragmented OT telemetry, limited correlation between OT and IT security data, and the need for clear escalation workflows for alerts generated by its security platform. To address these issues, the client deployed four Claroty sensors to capture and analyze OT network traffic, integrating this data into Microsoft Sentinel for centralized monitoring. The solution enhances visibility by allowing analysts to correlate alerts from Claroty with other security signals, thus improving incident triage and reducing false positives. CyberProof analysts provide ongoing monitoring and support to assess alert severity and prioritize risks. The integration of Claroty telemetry with Microsoft Sentinel and analyst-driven workflows has established a streamlined process for monitoring OT activity and escalating incidents for further action.
