Solution 1Recommended

Reach Out to the Microsoft Defender for Endpoint Community

General forums do not support specialized Defender services; you must contact the dedicated Defender team to investigate log ingestion failures.

Because Microsoft Defender EASM is a specialized security service, general IT support channels typically lack the backend access required to diagnose ingestion failures. Reaching out directly to the dedicated Microsoft Defender community ensures you are speaking with specialized engineers who can investigate workspace and telemetry issues.

Gather your workspace details

Collect your affected Sentinel workspace ID, the exact Sentinel table names missing data, the connector configuration details, and the precise timestamps of when the logs stopped appearing.

Visit the Tech Community

Navigate your browser to the official Microsoft Tech Community and locate the 'Microsoft Defender for Endpoint' section.

Submit your investigation request

Create a new post detailing the EASM log ingestion failure. Be sure to include all the technical details and telemetry data you gathered to expedite the investigation.

Reach Out to the Microsoft Defender for Endpoint Community

Include Error Logs: Do not share sensitive enterprise credentials or proprietary network IP addresses in public community posts; only share standard diagnostic IDs and timestamps.

Solution 2

Verify Data Connector Configuration in Azure

Ensure the connection between Microsoft Defender EASM and Microsoft Sentinel is still active and fully authorized.
