Incident Report

Summary AI Generated

**Proofpoint Security Awareness – Report Suspicious / CTR Threat Intelligence Disconnection** From approximately August 8–21, 2026 (lasting ~245 hours), US-based customers using Cloud Threat Response (CTR) lost connectivity to threat intelligence, resulting in missing Analyzer report results and no Threat Response Objects (TROs) being generated during the outage window. A fix was implemented on August 11, restoring normal processing for new submissions, though a backlog of affected emails from August 8–11 required reprocessing—causing an influx of TRO emails for impacted customers upon recovery. The incident was fully resolved on August 21 at 8:00 AM Eastern, with all reported emails confirmed as having been actioned per configured settings.

Customers in the US using Cloud Threat Response are currently failing to connect to threat intelligence for review. Admins will see missing results in the Analyzer report and will not receive TROs during this time. The team is actively investigating this issue.
