AI governance for Microsoft 365: See what your AI is doing with your data.

Sentinel gives security and IT leaders one view of Copilot and Copilot Studio agents in Microsoft 365: what they are asked, what they touch, how risky each one is, and where data is overshared.

Features

What Princeton Sentinel does

  • Agent activity log

    Every prompt, tool call, answer and cost, per agent and per user.

  • Prompt-injection screening

    A rules layer plus a locally hosted classifier checks each prompt, with no per-call fees.

  • Agent risk scoring

    Each agent scored on how it is configured and on what it actually does.

  • Oversharing & stale access

    Files shared too widely and accounts that should have been removed.

  • Executive posture view

    One page for leadership, with the trend over time.

  • Audit-ready records

    Purview audit data collected and kept for review.

    AI activity and data posture for Microsoft 365

    Sentinel watches Copilot and Copilot Studio agents in a Microsoft 365 tenant. It logs prompts and tool calls, scores each agent's risk, flags oversharing and stale access, and screens prompts for injection attempts with a classifier that runs locally at no per-call cost.

    • Every agent prompt screened
    • Runs inside the customer's own Azure tenant
