How to Build a RAG System on Private Company Data: Zero-Egress Blueprint
Step-by-step engineering blueprint for deploying a private vector mesh over confidential enterprise documents with strict role-based access control and zero cloud data leakage.

Should your enterprise fine-tune an open-source LLM or build a Retrieval-Augmented Generation pipeline? An architectural decision framework factoring data velocity, cost, and hallucination risk.


A common pitfall among corporate R&D teams is assuming that fine-tuning is the "advanced version" of RAG. In reality, they solve two entirely orthogonal engineering challenges.
If an enterprise attempts to bake its internal corporate policies into model weights via fine-tuning, two problems immediately occur: catastrophic forgetting of baseline reasoning capabilities, and an inability to cite the exact source document during an internal audit.
Choose RAG whenever your data updates frequently, requires strict source citations for audit compliance, or must enforce role-based access control (RBAC).
No. Fine-tuning models on factual enterprise data does not guarantee accurate recall and frequently produces confident hallucinations without a grounding vector database.
