Integrating Microsoft Entra with Nmap for Identity-Linked Network Scans

The scan finished in less than a minute. Every port on the target reported back with precision. The integration between Microsoft Entra and Nmap worked exactly as intended.

Microsoft Entra delivers identity and access control for cloud and on-prem systems. Nmap provides deep network reconnaissance. Combined, they give security teams a direct view of who is on the network and what they can reach. This is not theory. With a simple workflow, you can tie Entra’s directory data to Nmap’s host discovery and service enumeration.

Start with Entra API access. Use it to pull the list of active devices and accounts. Feed that data into Nmap’s scanning engine. Nmap will map IP addresses, ports, services, and OS fingerprints. You can cross-check those results against Entra’s identity records to flag unauthorized or suspicious assets. No guesswork. No blind spots.

The benefits are clear:

• Identify shadow infrastructure linked to stale or compromised accounts.
• Confirm network exposure for assets tied to specific identities.
• Automate reports that connect identity activity with live network states.

Security audits improve when the output includes both account metadata and network details. Nmap scripts can extend the scans to trigger alerts when Entra records change or when unexpected ports open. Microsoft Entra’s logs give timestamps; Nmap’s results give the technical proof. Together they form a complete picture.

For many teams, integration is a small matter of Python scripting. Query the Entra Graph API, normalize results, run Nmap scans with targeted IP ranges, and push findings into SIEM. The approach scales. Cloud-only, hybrid networks, remote endpoints — all covered.

If real-time, identity-linked network scans sound like the missing link in your security process, connect Microsoft Entra to Nmap today. See it live in minutes with hoop.dev.
