Turning on Microsoft 365 Copilot for everyone can turn a decade of loose SharePoint permissions into a data exfiltration engine. This episode is for IT leaders and architects who need a practical governance model for Copilot, from prompt injection risks and risk-tiered rollout to Purview, DLP and oversharing cleanup. Learn how to make Copilot secure, auditable and worth its license cost.

Key takeaways
Worth quoting
“Microsoft is telling the truth when they say co-pilot will not show a user a file they don't have permission to see. That is the baseline, but that baseline assumes your permissions are correct.” – Mirko Peters (01:47)
“If a sensitive document is technically open, it is now functionally public within your tenant.” – Mirko Peters (02:32)

In this episode
- 00:00 – Copilot as a structural audit
- 04:18 – The new attack surface: prompt injection
- 08:07 – Risk-tiered rollout
- 11:35 – Purview and interaction DLP
- 19:01 – The oversharing multiplier
- 22:44 – AI content lifecycle, prompt literacy and usage policy
- 32:17 – ROI, citizen agents, audit and executive trust
- 50:38 – Roadmap, exceptions, culture and the 90-day plan
Key takeaways
- Copilot respects permissions, so a decade of oversharing in SharePoint and Teams becomes an AI exposure problem that must be remediated before licenses are assigned.
- Roll out in risk tiers and enforce boundaries with Microsoft Purview: sensitivity labels, adaptive scopes, label inheritance and interaction-level DLP for prompts and responses.
- Prove realized value with A/B tests and capacity metrics, govern citizen-built agents and exceptions explicitly, and build a governance-aware culture with champions.
