Latest Message<\/th>\nTitle: Some admins may experience a 30-minute gap in security telemetry and alerts in Microsoft Defender for Endpoint<\/p>\n

User impact: Admins may experience a 30-minute gap in security telemetry and alerts in Microsoft Defender for Endpoint.<\/p>\n

More info: Impacted admins may experience a point-in-time gap of approximately 30 minutes in Microsoft Defender for Endpoint telemetry data when viewing information in the Microsoft Defender portal and Microsoft Sentinel, as the impacted data wasn’t ingested.<\/p>\n

Current status: We\u2019ve determined that an authentication component misconfiguration is causing authentication issues within a core part of the Microsoft Defender for Endpoint service, resulting in telemetry data not being ingested. We\u2019re deploying a fix to restore the authentication component and stabilize ingestion, which will allow the missing data to be re-ingested.<\/p>\n

Scope of impact: Some admins relying on security telemetry reporting in Microsoft Defender for Endpoint may be impacted. This information may be updated as our investigation continues.<\/p>\n

Start time: Wednesday, May 20, 2026, at 7:30 AM UTC<\/p>\n

Root cause: An authentication component misconfiguration is causing authentication issues within a core part of the Microsoft Defender for Endpoint service, resulting in telemetry data not being ingested.<\/p>\n
