Custosa – Permission and compliance layer for Enterprise AI

Summary: Custosa enforces runtime access control for enterprise AI by filtering data based on user identity and compliance policies before it reaches large language models. It integrates with retrieval-augmented generation (RAG) and agentic pipelines to ensure context is tailored per user while meeting regulatory standards like HIPAA, ITAR, and SOC 2.

What it does

Custosa sits between your data sources and the LLM, applying user-specific permissions and compliance rules to filter context at runtime. It compiles access policies dynamically to control what information the model can access depending on who is querying.

Who it's for

It is designed for enterprises deploying AI agents that require strict data access controls and compliance adherence in regulated industries.

Why it matters

Custosa addresses the risk of LLMs accessing unauthorized or sensitive data by enforcing row-level permissions and privacy controls before any data reaches the model.
