Network discovery is the systematic sweep of a network to identify devices, services, and topology. It typically combines ping, ARP, SNMP, port scans, and protocol-specific probes (mDNS, NetBIOS, LLDP) to build a picture of what is actually on the wire — not just what is supposed to be.
IT Glossary
What is network discovery?
The continuous practice of finding every device on a network — including the ones nobody told you about.
What the practice is actually for.
- Shadow IT is the single biggest gap in most asset inventories — and the easiest to miss
- Auditors will ask "how do you know what is on your network?" — and they expect a real answer
- A new device joining the network is often the first signal of a compromise or a misconfiguration
The practical version.
Continuous network sweeps per customer site, with SNMP, port scans, and CVE matching. Diffs reported as alerts. Topology map built automatically. The unmanaged switch is found the day it shows up — not the week before the audit.
