A database security feature that restricts access to specific rows of data based on the user's identity or role.
RLS is a database security feature that restricts which rows a user can see based on their identity.
Imagine a SaaS app with 1,000 companies in one database table. RLS ensures that when Company A queries `SELECT * FROM invoices`, they only receive their own invoices, even though Company B's invoices live in the exact same table.
It enforces security at the database engine level (Postgres, SQL Server), not just in the application code. Even if the application code has a bug or a developer forgets a `WHERE` clause, the database itself will refuse to return unauthorized data.
