Shadow AI

Reviewed 19 July 2026Canonical definitionPart of: Runtime Control & Guardrail Terms →

Shadow AI is any AI tool, model, or agent used inside an organisation without the knowledge or approval of the teams accountable for it. The problem is rarely the tool itself. It is the blind spot: real work is flowing through a system nobody is measuring, so when it returns a wrong answer or a prompt carries data somewhere it should not go, there is no record of what happened. Shadow AI usually appears because the sanctioned route was slower than the unsanctioned one.
