Guideline implemented a User-Defined Function (UDF) proxy to enforce granular data access controls in ThoughtSpot's GenAI analytics tool, Spotter. The solution validates every dynamically generated query against row-based, column-based, and intersection-based permissions before execution, preventing the mosaic effect while maintaining self-service flexibility. This approach provides auditable, policy-driven data governance without requiring significant architectural changes, enabling secure GenAI deployment in production environments with complex access requirements.
