Stop relying on application-layer filters to secure your data. Learn how to use Supabase Row Level Security (RLS) to push authorization into the database for robust multi-tenant isolation.
Learn how to move from manual data filtering to Row-Level Security (RLS) to enforce per-user data isolation transparently without rewriting application logic.
Learn how to decide between permissive and restrictive Row Level Security policies in Supabase, see a trade‑off table, and implement an owner‑only policy with verification steps.
Stop relying on API filters for data isolation. Learn how to use Supabase Row Level Security (RLS) to enforce multi-tenant boundaries directly in your PostgreSQL schema.
Stop writing middleware for basic authorization. Learn how to use Supabase Row Level Security (RLS) to move your access control directly into Postgres for a more secure, scalable API.
Recursive Policy Evaluation Supabase leverages PostgreSQL Row Level Security (RLS) to enforce data access via auth.uid() . In schemas where a table contains a self-referencing foreign key—such as a categories table with a parent_id column—policies often need to check the permissions of the parent record to determine access to the child record. Constraint and
SurrealDB utilizes PERMISSIONS clauses on tables and records to enforce fine-grained access control. These expressions typically evaluate the current session's user attributes against record data to determine if a SELECT , CREATE , UPDATE , or DELETE action is permitted. When implementing DEFINE ROLE for scalable management, there is a need to handle overlap
