Hello Friends,
Welcome back to the Part 4. In the first three parts of this series, we built a complete pipeline: Part 1 explained the security problem and why tenant visibility matters, Part 2 showed the PowerShell technique for resolving storage FQDNs to tenant IDs using the WWW-Authenticate header, and Part 3 connected Azure Firewall logs through KQL queries to feed that script automatically.
The pipeline we have so far produces a report with an FQDN, a tenant ID, and an IsOwnTenant flag. That is useful, but it leaves two practical gaps. First, tenant IDs are GUIDs: machine-readable, but not something a security team can act on. When a report tells you that eight storage accounts belong to an unknown tenant, you want a name, not a GUID. Second, the report is a manual one-time snapshot. In practice, you want something that flags new unknown tenants as they appear in your firewall traffic without anyone having to remember to run a script.
