SecOps Signal analysisWhy it matters
Defenders must ensure MDI sensors deployed in GCC environments can resolve and communicate with the new DNS zone target to maintain uninterrupted threat detection and telemetry ingestion.
Operational impact
MDI sensors in GCC environments may experience connectivity disruptions or telemetry gaps if local DNS or network rules block the new zone target.
Section 03 · Recommended actions
- Review existing network and DNS rule sets for MDI sensors.
- Ensure the sensor DNS prefix allows access to *.atp.gcc.azure.com in GCC tenants.
What to check
- Verify outbound firewall and DNS configurations for MDI sensors in GCC environments.
- Confirm that sensors can successfully resolve and communicate with *.atp.gcc.azure.com.
