Why it matters
Excessive agency AI is a real governance gap for enterprises deploying autonomous Copilots, where over-permissioned agents can scan and extract entire SharePoint libraries in seconds.
CyberOne's blog explains the risk of excessive agency AI (OWASP LLM08), where autonomous agents such as Microsoft 365 Copilots are granted permissions beyond what they need, enabling data exfiltration, privilege escalation, and system instability. The piece argues traditional RBAC fails to constrain dynamic AI workflows and promotes behaviour-based monitoring and managed security services for governance.
