Organizations sharing Power BI reports with external users should consider risks such as unauthorized data access, accidental exposure of sensitive information, and excessive sharing permissions. External users may gain access to more data than intended if Row-Level Security (RLS) is misconfigured or workspace permissions are too broad.

Other risks include data leakage through report exports, screenshots, downloads, and improperly configured sharing links. Organizations should also verify external identities, manage guest access through Microsoft Entra ID, and review permissions regularly.

To reduce these risks, use least-privilege access, configure RLS and sensitivity labels where appropriate, restrict exports when necessary, and monitor activity through audit logs. External sharing should be controlled, monitored, and reviewed regularly to ensure business data remains protected.
