When you enable Row-Level Security in Mosh, every SELECT, UPDATE, and DELETE operation passes through your defined policies. These policies are written directly against the structure of your data, so they adapt automatically as your schema evolves. Permissions are not baked into application code—they are enforced at the database layer, where they cannot be bypassed by mistakes higher up the stack.
This model stops data leaks before they happen. Each tenant sees only its own rows, regardless of how complex the queries are. Admins can design exceptions for auditors or power users without breaking isolation for the rest. You can bind rules to user IDs, roles, or any other field in your tables.
Because Mosh integrates Row-Level Security as a core feature, setup is straightforward. You define policies once, and they apply consistently across all queries. There’s no need for custom middleware or per-endpoint checks. The database is the guardrail, the source of truth.
