Securing the Agent: Vendor-Neutral, Multitenant Enterprise Retrieval and Tool Use

Francisco Javier Arceo, Varsha Prasad Narsing

Abstract

Retrieval-Augmented Generation (RAG) and agentic AI systems are increasingly prevalent in enterprise AI deployments. However, real enterprise environments introduce challenges largely absent from academic treatments and consumer-facing APIs: multiple tenants with heterogeneous data, strict access-control requirements, regulatory compliance, and cost pressures that demand shared infrastructure. A fundamental problem underlies existing RAG architectures in these settings: retrieval systems rank do
