Microsoft 365 Integration

Unified visibility across Exchange, SharePoint, Teams, and Entra ID.

What this integration does

Microsoft 365 meets agentic SOC

Microsoft 365 is the productivity backbone of most enterprise environments — and a primary target for email compromise, OAuth abuse, and insider data theft. ManySignal ingests M365 audit logs, Entra ID sign-ins, and Defender for Office 365 alerts via the Microsoft Graph API, correlating SaaS activity with endpoint and identity signals.

Microsoft 365 Integration: frequently asked questions

Does the integration require a Defender for Office 365 licence?

No. Base Unified Audit Log ingestion works with any M365 plan that has auditing enabled. Defender for Office 365 alert ingestion requires the Defender for Office 365 Plan 1 or Plan 2 licence.

How is Teams data handled?

ManySignal ingests Teams audit metadata (channel events, membership changes, sharing events) but does not ingest message content. Only activity telemetry is processed.
