Importer Data Types

• Asset Details Enrichment and Create New in Vantage

  Cisco Umbrella supplies records including roaming client hostname, IP addresses, MAC address, OS, internal/external network identity, site assignment and last-seen timestamp — to enrich existing Vantage assets and create new asset records for endpoints not yet observed on the OT network.

Joint Use Cases

• Correlating Cisco 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 Cisco Umbrella record in Vantage to review recent policy decisions, posture state and connection telemetry, all without leaving the Vantage investigation workflow. This cross-layer correlation surfaces whether a network-layer anomaly coincides with activity observed by Cisco, reducing the time needed to confirm or dismiss an incident.

• Closing asset inventory gaps across IT and OT

  Devices recorded by Cisco Umbrella but not yet observed by Nozomi network sensors are automatically created as new asset records in Vantage, populated with device name, OS, posture state and user/identity context drawn from the Cisco 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.

• Validating zero-trust enforcement on OT-adjacent endpoints

  Endpoints recorded by Cisco Umbrella as policy-managed are reconciled with assets observed crossing into OT-adjacent network zones in Vantage. Operations teams can verify that every device touching the OT boundary is enrolled in the zero-trust access platform, surfacing unmanaged or stale clients that should be remediated before further OT exposure.
