Passive discovery is enabled by default for Infoblox Threat Defense. Passive discovery is a less taxing approach for discovering assets in your network infrastructure. In conjunction with Threat Defense, Passive Discovery uses data from DHCP logs (both NIOS and Universal DDI) along with information discovered from Infoblox-managed endpoints to provide enhanced visibility into your network devices.
> ⚠️ Discovery data updates for DNS and IPAM are not supported if your account is configured with only the Infoblox Threat Defense license entitlement.
Based on the ingested data, you can view discovered data in the **Security** > **Assets** sub-workspace of the Infoblox Portal, depending on your account’s subscription. For information on the **Security **workspace, see *[Viewing Security Workspace](https://docs.infoblox.com/space/BloxOneCloud/1588592724/Viewing+Security+Workspace)*. For information on the** Assets** workspace, see *[Viewing the Network Assets Sub-Workspace](https://docs.infoblox.com/space/BloxOneCloud/847119201)*.
Depending on whether your account is subscribed to the Universal DDI or Threat Defense licenses, the following table describes the different scenarios you may experience when using Passive Discovery.
