Row-Level Security (RLS)

RLS filters the rows visible to a user based on a DAX expression that runs in the user's context. Common patterns:

Object-Level Security (OLS)

OLS hides entire tables or columns from users in specific roles, rather than filtering rows.

Operational considerations

For Power BI semantic models with mixed-sensitivity data shared across heterogeneous audiences, RLS and OLS are how you serve everyone without proliferating the model. Built once, applied consistently, audited centrally.
