Tenable

Importer Data Types

• Asset Details Enrichment and Create New in Vantage

  Tenable IO supplies records including asset UUID, hostname, IPv4 and IPv6 addresses, MAC, OS, system type, FQDN, tags and last-authenticated-scan timestamp — to enrich existing Vantage assets and create new asset records for endpoints not yet observed on the OT network.

• Asset Software Inventory Import

  Tenable IO reports installed software detected by Nessus credentialed scans including product, version and publisher. 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

  Tenable IO produces plugin findings linked to CVE identifiers with CVSS v3 scores, VPR scores and remediation steps. These findings are imported into Vantage as CPE-correlated vulnerability records, enabling prioritized remediation tracking within the Nozomi asset context.

Joint Use Cases

• Correlating Tenable 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 Tenable IO record in Vantage to review last scan date, open vulnerability count and highest-severity finding, all without leaving the Vantage investigation workflow. This cross-layer correlation surfaces whether a network-layer anomaly coincides with activity observed by Tenable, reducing the time needed to confirm or dismiss an incident.

• Closing asset inventory gaps across IT and OT

  Devices recorded by Tenable IO but not yet observed by Nozomi network sensors are automatically created as new asset records in Vantage, populated with hostname, OS, FQDN, agent ID and last-scanned timestamp drawn from the Tenable 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 Tenable IO 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 Tenable-confirmed vulnerability data from a single Vantage dashboard.
