Overview

Every Copilot interaction generates an audit event (RecordType 261, CopilotInteraction) in Microsoft's Unified Audit Log. These records capture who used Copilot, when, in which app, and what files were referenced. But on E3 licenses, Microsoft retains this data for just 180 days. Even E5 provides only one year. HIPAA requires 6 years. SOX mandates 7 years. And the average time to detect a sophisticated data breach is 290 days, beyond E3's entire retention window.

Compass Copilot Audit Log Retention subscribes to the Office 365 Management Activity API and captures CopilotInteraction events in near-real-time, storing structured records in your Azure environment indefinitely. Each record includes user identity, timestamp, host app, accessed resources, sensitivity label IDs, and plugin usage.

  • Regulatory compliance for HIPAA, SOX, PCI DSS
