Secure Onboarding of Microsoft 365 Copilot & Copilot Cowork
We help enterprise teams adopt Microsoft 365 Copilot — and Copilot Cowork in particular — securely and under control, with clear permissions, effective governance, and no uncontrolled data exposure in existing workflows.
Why This Matters Now
Copilot Cowork goes beyond chat and summarization: it sends emails, drafts documents, schedules meetings, and manages files — autonomously, across multiple steps, with exactly the permissions of the user it acts on behalf of via Microsoft Graph.
In most tenants, that means historically grown oversharing becomes a real risk. Rolling out Copilot and Cowork into production without first reviewing permissions and sensitivity labels carries existing weaknesses straight into an agentic context.
Agentic AI amplifies whatever's already there — productivity as much as weaknesses.
The Agentic AI Risk Landscape
Agentic AI systems are amplifying real-world security incidents faster than governance can keep pace — permission hygiene and oversight are now board-level concerns.
54%
of organizations report AI agent security or data privacy incidents
More than half of organizations experienced a confirmed or suspected AI agent security or data privacy incident in the past 12 months — clear evidence of real-world risk before agents gain broad access.

80%
of organizations report risky AI agent behavior
80% of organizations say they have encountered risky behaviors from AI agents, including improper data exposure and access to systems without authorization.

4.5×
more security incidents from over-privileged AI permissions
Organizations granting AI systems excessive permissions experience 4.5× more security incidents than those enforcing least privilege (76% vs. 17% incident rate) — direct support for least-privilege and sensitivity-labeling as complementary safeguards.
