Why it matters
Shadow AI expands the attack surface of organisations, giving defenders unmanaged AI agents and unsanctioned data flows that can be exploited or leak sensitive information outside governance controls.
An NCSC blog post examines the security risks of 'shadow AI' — the use of unapproved AI tools by employees — citing research that 71% of employees reported using AI tools not sanctioned by their employer. It outlines risks including exposure of sensitive data, loss of data visibility and control, and new attack opportunities where attackers could exploit vulnerabilities in AI agents to gain their access and privileges.
