Importer Data Types

• Asset Details Enrichment and Create New in Vantage

  Microsoft Defender for Endpoint supplies records including device name, IP and MAC addresses, OS platform and version, onboarding status, exposure level, risk score and last-seen timestamp — to enrich existing Vantage assets and create new asset records for endpoints not yet observed on the OT network.

• Asset Software Inventory Import

  Microsoft Defender for Endpoint reports installed application name, vendor, version and weakness count from the Defender Vulnerability Management inventory. This per-asset software list is imported into Vantage, giving OT security teams an authoritative view of what is running on each observed device.

• Asset CPE and CVE Import

  Microsoft Defender for Endpoint produces CVE identifiers, CVSS scores, exploit availability and recommended security updates from Defender Vulnerability Management. These findings are imported into Vantage as CPE-correlated vulnerability records, enabling prioritized remediation tracking within the Nozomi asset context.

Joint Use Cases

• Correlating Microsoft signals with OT network alerts

  When Nozomi Vantage raises an anomaly alert for a device inside an OT segment, the analyst can pivot to the same asset's Microsoft Defender for Endpoint record in Vantage to review recent detections, prevention events, isolation status and agent health, all without leaving the Vantage investigation workflow. This cross-layer correlation surfaces whether a network-layer anomaly coincides with activity observed by Microsoft, reducing the time needed to confirm or dismiss an incident.

• Closing asset inventory gaps across IT and OT

  Devices recorded by Microsoft Defender for Endpoint but not yet observed by Nozomi network sensors are automatically created as new asset records in Vantage, populated with hostname, OS, agent status and last-seen timestamp drawn from the Microsoft management plane. OT operations teams can audit the resulting unified inventory to identify unmonitored or underprotected assets in industrial and critical infrastructure zones, then prioritize sensor deployment accordingly.

• Prioritizing vulnerability remediation on critical OT assets

  CVE findings and severity scores imported from Microsoft Defender for Endpoint are surfaced alongside Nozomi's OT risk scoring for each asset, allowing security engineers to rank remediation effort by both vulnerability severity and the operational criticality of the affected device. This joint view enables compliance reporting workflows, such as IEC 62443 gap assessments, to reference both network-observed risk and Microsoft-confirmed vulnerability data from a single Vantage dashboard.
