Private AI Architecture

Private RAG Systems for Secure Enterprise Knowledge

Turn internal documents and operational data into a permission-aware answer layer without copying sensitive knowledge into a public AI service.

The enterprise problem

Designed around the risk you need to remove.

Enterprise search fails when people cannot find the right version of a policy, contract, runbook, or technical record. A private retrieval-augmented generation system connects those sources to grounded answers while preserving document permissions, provenance, and the ability to inspect how an answer was produced.

Technical methodology

A system boundary you can inspect.

The architecture is decomposed into explicit layers so data movement, authorization, operational ownership, and failure behavior remain visible.

  1. 01

    Ingest and classify

    Connectors extract content, metadata, ownership, retention, and source-system permissions.

  2. 02

    Hybrid index

    Lexical search, vector retrieval, metadata filters, and reranking work together for high-recall discovery.

  3. 03

    Grounded generation

    A private model receives only authorized context and returns citations to the source material.

  4. 04

    Feedback loop

    Evaluation sets, user feedback, retrieval traces, and drift monitoring improve the system over time.

Security & compliance

Controls belong in the design.

Security is not a deployment afterthought. It is expressed through identity, isolation, data handling, auditability, and the ability to recover safely.

  • Document-level and row-level authorization inherited from source systems
  • Private embeddings and indexes stored in the approved environment
  • Source citations and retrieval traces for every answer
  • Retention, deletion, and re-indexing controls
  • PII redaction and prompt-injection defenses at ingestion and query time

What this enables

Built for ownership, trust, and the next stage of growth.

  • Faster access to trusted internal knowledge
  • Lower hallucination risk through citations and evaluation
  • A measurable search experience for teams, not just a chat interface
