Description The issue with Mandiant Threat Defense and Mandiant Managed Defense has been mitigated as of Wednesday, 2026-05-20 22:29 US/Pacific. The issue was caused by excessively large detections from a third-party vendor signature that consumed processing resources and slowed the processing of other detections. We thank you for your patience while we worked on resolving the issue. Customer Symptoms An internal alert processing issue delayed Mandiant analysts from triaging and investigating detections. Data ingestion from security devices was not impacted. This issue may have caused investigation reports to be delayed.
