Architecting Private RAG & LLM Infrastructure for Enterprise SaaS
A deep dive into building air-gapped, zero-leakage Retrieval-Augmented Generation systems using PostgreSQL pgVector, Go, and Python.
Architecting Private RAG & LLM Infrastructure for Enterprise SaaS
Enterprise organizations cannot afford to leak confidential customer data, intellectual property, or financial records to public AI training pools.
The Private RAG Blueprint
At Zion Tech, our engineering squads implement private RAG architectures utilizing:
- Isolated pgVector storage with row-level security per tenant.
- Local embedding inference running on dedicated cloud VPCs.
- Strict audit logging tracking every token consumed and retrieved context chunk.
Zero Data Retention Guarantees
By deploying self-hosted models or private enterprise endpoints, sensitive documents never leave your security boundary.
