Qualys

Importer Data Types

• Asset Details Enrichment and Create New in Vantage

  Qualys supplies records including asset hostname, IPs, MAC, OS and version, fully qualified domain name, asset tags, agent ID, network and last-scanned timestamp — to enrich existing Vantage assets and create new asset records for endpoints not yet observed on the OT network.

• Asset Software Inventory Import

  Qualys reports installed software inventory including product, vendor, version and category from Qualys Cybersecurity Asset Management. 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

  Qualys produces QID findings mapped to CVE identifiers with CVSS scores, severity, exploit availability and remediation guidance from Qualys VMDR. These findings are imported into Vantage as CPE-correlated vulnerability records, enabling prioritized remediation tracking within the Nozomi asset context.

Joint Use Cases

• Correlating Qualys 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 Qualys 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 Qualys, reducing the time needed to confirm or dismiss an incident.

• Closing asset inventory gaps across IT and OT

  Devices recorded by Qualys 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 Qualys 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 Qualys 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 Qualys-confirmed vulnerability data from a single Vantage dashboard.
