SharePoint Copilot Data Exposure Assessment

SharePoint and Teams permission sprawl can remain hidden until Copilot makes old content searchable through natural language. SCS tests whether sensitive sources become discoverable to scoped identities.

What this assessment answers

• Can standard users discover sensitive SharePoint or Teams content?
• Do Copilot citations reveal sensitive sites, file names, paths, or labels?
• Are executive, HR, legal, finance, audit, or workforce planning sources exposed?
• Do seeded canaries appear to roles that should not see them?
• Can likely access paths explain why the content was reachable?

What we test

• Overshared SharePoint sites
• Inherited permissions
• Broad Teams membership
• OneDrive folder sharing
• Organization-wide links
• Sensitive metadata leakage
• Canary retrieval
• Label and protection gaps

Outputs

• Copilot Exposure Summary
• Role Exposure Matrix
• Sensitive Category Findings
• Source and citation evidence
• Optional access-path root cause context
• Remediation actions
• Retest plan

Operator-led, evidence-first assessment.

SCS validates what Copilot surfaces from existing access. The assessment does not require claiming that Copilot bypassed controls when the root cause is permission sprawl.
