PAR Technology builds multi-tenant LLM analytics with row-level security on AWS

PAR Technology deployed a three-layer security architecture for its text-to-SQL analytics agent serving 300+ restaurant businesses, combining AWS SigV4 request signing, semantic validation on Amazon Bedrock, and Split-Plane SQL to enforce row-level data isolation. For commerce platforms handling multi-tenant data, the design proves that LLMs alone cannot enforce security boundaries—architecture-level controls are essential to prevent cross-tenant data exposure even if the model is compromised.
