Key point

Microsoft has identified 'Shadow AI'—AI used beyond IT department control—as a major security threat for enterprises.

Details

Microsoft warned that 'Shadow AI', used within enterprises without IT department management or visibility, is emerging as a new corporate risk.

Unlike existing Shadow IT or Shadow Analytics, AI agents carry a distinct risk in that they can directly perform 'Actions' on behalf of users across various tools, endpoints, and SaaS environments.

Many enterprises are likely already operating uncontrolled AI agents without being aware of it, which is expected to pose a serious challenge to corporate governance and security management.
