Before rolling out Microsoft Copilot, understand the oversharing risk in your SharePoint and OneDrive — and fix what needs fixing first.
Microsoft Copilot uses the permissions of the signed-in user to access content. If someone has SharePoint access they shouldn't have — through a permission inheritance nobody remembers, an external sharing link from 2019, or a Teams site that defaulted to organization-wide access — Copilot will happily surface that content in the user's next prompt.
Most organizations we assess have meaningful oversharing. Not from negligence, but from years of accumulated sharing decisions that no one ever audited. Copilot exposes that history all at once. The right answer isn't to delay Copilot indefinitely — it's to find the oversharing, fix what matters, and roll Copilot out with confidence.
This assessment uses Microsoft's own tooling — Data Security Posture Management (DSPM) for AI, SharePoint Advanced Management, sensitivity label reports. We map the risk, prioritize the remediation, and deliver a roadmap your team can execute before licenses are purchased.
A DSPM for AI baseline assessment showing where oversharing exists, scored and ranked by business impact. SharePoint and OneDrive permission analysis identifying sites and files exposed beyond their intended audience.
A sensitivity label coverage report — what data should be labeled but isn't, what DLP policies are missing, where the gaps in AI-specific governance are.
A prioritized 30/60/90 day remediation roadmap, a license rollout plan by department starting with the lowest-risk groups, and a recommended adoption strategy that doesn't force every user into Copilot on day one.
Weeks 1–2. Enable DSPM for AI in Microsoft Purview. Run SharePoint Advanced Management reports on oversharing. Map current sensitivity label coverage across the tenant. Pull the initial data without changing anything yet.
Weeks 2–3. Review the findings with business stakeholders. Score oversharing risk per site, per group, per content type. Identify the high-risk content that needs to be fixed before Copilot rolls out, versus lower-risk findings that can be addressed over time.
Weeks 4–5. Build the 30/60/90 day remediation roadmap. Recommend a license rollout strategy starting with departments that have lowest exposure. Document the adoption and change management plan.
