Radius Row-Level Security (RLS) enforces per-row access rules at the database level. Each record carries conditions. Each user gets only the rows they’re allowed to see. No extra filtering in app code. No risk of leaking data through lazy queries. The database becomes the gatekeeper.
With Radius, policies live close to the data. You define rules based on tenant ID, user roles, or any attribute. The database engine applies them in every query—SELECT, UPDATE, DELETE—automatically. This eliminates duplicated logic across services and prevents bypass through forgotten filters.
RLS is critical in multi-tenant and sensitive-data environments. Traditional permission checks in application code can be skipped by accident or misapplied when APIs evolve. Radius moves this responsibility into the database layer, where it is consistent and unavoidable. Queries that don’t meet the policy fail.
Radius implements row-level permissions with high performance. Policies are compiled into query plans. No slow middleware. No fragile code. Security is enforced by design. This approach guards against unauthorized reads and writes, even when developers operate under pressure or when new team members join.
