Metadata filters are the most common approach to RAG access control. They're also fundamentally insufficient. Here's why app-level filtering can't replace a dedicated permission layer.
Four approaches to RAG authorization, compared: no auth, metadata filters, app-layer RBAC, and a dedicated permission layer. Pros, cons, and when each makes sense.
DIY RAG authorization requires a policy engine, metadata resolution, audit logging, connector adapters, and identity sync. Here's what it actually takes to build it yourself.
Vector databases retrieve based on embedding similarity. They don't know who's asking. They don't check permissions. They just return the closest matches. This is the AI security gap — and it's wider than most teams realize.
Gateco assigns each connector a readiness level from L0 to L4 based on its security capability — not a percentage, but a progression through increasingly granular enforcement. Here's what each level means and how to reach it.
SaaS platforms embedding LLM features must prevent cross-tenant data leakage in shared RAG infrastructure. Here's how to enforce tenant isolation at the retrieval layer.
