Automated discovery and a healthy CMDB give ITAM, security and service teams an accurate, continuously updated view of the estate.
What discovery does
Discovery tools scan networks, endpoints, cloud accounts and SaaS platforms to identify devices, installed software, configurations and relationships — agent-based, agentless or both.
Discovery and the CMDB
Discovered data feeds the Configuration Management Database (CMDB), where it is normalised and reconciled with purchase records. This links assets to services, users and contracts.
Common pitfalls
Duplicate records, unmanaged remote devices, shadow IT SaaS and stale data. Set reconciliation rules, define authoritative sources per attribute, and flag assets not seen within 30 days.
Measuring success
Track discovery coverage (target 95%+), CMDB accuracy, and time-to-detect new or unknown devices. Accurate discovery also strengthens cybersecurity by exposing unpatched or unauthorised assets.
