AWS Details Multi-Tenant LLM Analytics With Row-Level Security via Cryptographic Request Signing

AWS Machine Learning Blog·medium signal

AWS and PAR shared a production multi-tenant LLM analytics architecture that enforces row-level security through a three-layer design, including cryptographic request signing with AWS keys. The pattern addresses a recurring enterprise blocker: letting an LLM agent query shared data without leaking across tenant boundaries. It's a useful reference for anyone shipping agentic analytics on shared datasets.
