What is Regulatory Sandbox?

In practice, a regulatory sandbox is used to pilot a system with real users or realistic data under limits on scale, duration, geography, or risk exposure. Participants typically must document the use case, controls, monitoring plan, and exit criteria, and regulators may require reporting on incidents, bias, safety, or consumer harm during the test period.

For compliance teams, a sandbox can reduce uncertainty by clarifying how existing obligations apply to an AI use case and by creating a documented pathway for testing. It is relevant across AI governance and financial-services innovation regimes, including EU and national implementations tied to the EU AI Act, the UK approach to regulatory innovation, and sector-specific supervisors that use sandbox-style pilots for fintech, health, and other regulated uses.
