RLS
Row-Level Security (RLS) is a native PostgreSQL feature that allows fine-grained access control rules to be defined at the database level. Through policy definitions, it specifies which users can perform which operations on which rows, enabling precise control over data visibility and modification at the row level.
Core Facts
Row-Level Security (RLS) pushes permission checks down to the database layer, so that even if there are vulnerabilities in the application layer code, the database layer will not return unauthorized data.

Timeline (last 90 days)
An RLS policy of USING (true) means all rows are unconditionally allowed through, which is equivalent to having no RLS enabled.
In Supabase, RLS is disabled by default on every table created with SQL.
For platforms that auto-generate code, enabling RLS by default is especially important because auto-generated API routes may have unexpected permission vulnerabilities.
Newly created Supabase tables have RLS enabled by default but contain no policies, causing all requests to be denied; the 'Auto RLS' option generates reasonable initial policies when the table is created.
Delegated authentication ensures that the agent's access scope for semantic models and reports, as well as RLS and OLS restrictions, is consistent with the logged-in user and cannot bypass security policies.
RLS restricts users to viewing only the data rows within their permission scope by defining roles and DAX filter rules in the semantic model.
Early versions of Supabase had RLS disabled by default, making newly created data tables fully readable by anyone holding the project API key.
Row Level Security (RLS) is the core mechanism Supabase uses to protect data, but if not properly enabled and configured in the default state, data tables may be completely open to the public.
Developers should confirm that RLS is enabled on every sensitive data table and verify that policies are in effect, should not trust default security, and should perform access tests from an anonymous user perspective before going live.
PostgreSQL natively supports Row-Level Security (RLS), which can implement tenant isolation by setting session variables via SET app.current_tenant.
