BI Governance & Security

While security rules were already established to protect sensitive data, the existing model lacked the flexibility to adapt to the complexity of all business units. The challenge was to evolve this governance towards multi-axis management, capable of offering much finer access granularity at the group scale. I implemented a dynamic security engine using PySpark to industrialize Row Level Security (RLS). This system now cross-references multiple criteria (geographical, hierarchical, functional) in synchronization with Azure Active Directory. This evolution extended security coverage to all entities with surgical precision, ensuring perfectly compartmentalized and automated information distribution.
