How it works
From blind spots to a remediation queue in three steps
No agents to install on endpoints. No copy of your data shipped to a vendor cloud. Sentinel runs where your Microsoft 365 data already lives.
Ingest & score
A scheduled worker syncs your SharePoint, OneDrive, sharing, and Copilot telemetry into your database, then scores every site and agent for exposure.
See & remediate
Dashboards surface the highest-risk sites and agents with plain-language summaries. Admins revoke links, quarantine agents, and export audit logs - with one click.
Data governance & AI observability
Why security teams run Princeton Sentinel
One platform for the two risks Microsoft 365 grew faster than anyone could govern: over-shared data and ungoverned AI agents - data security posture management and AI observability, together.
Data risk, scored per site
Every SharePoint site gets an exposure score from real signals - anonymous links, external access, dormancy - with AI summaries and one-click revoke.

Copilot Studio agents scored for reach, tool access, and credential hygiene - plus live telemetry, safety-incident tracking, and quarantine controls.
