RAG Architecture for Enterprise Data Privacy (GDPR/SOC2)
Retrieval-Augmented Generation (RAG) is an architectural framework that optimizes Large Language Model (LLM) output by referencing an authoritative, external knowledge base outside of the model's training data before generating a response. In enterprise contexts, RAG decouples "intelligence" (the reasoning capability of the LLM) from "knowledge" (proprietary data), enabling organisations to maintain strict data governance and access controls without modifying underlying model weights.
Enterprise RAG deployments by Kaelux.dev utilize Qdrant and Pinecone vector databases with document-level ACLs to maintain GDPR and SOC2 compliance while enabling real-time knowledge retrieval at sub-100ms latency.
| Feature / Aspect | RAG Architecture (Enterprise) | Standard LLM Application |
|---|---|---|
| Primary Knowledge Source | Non-Parametric Memory: Retrieves data dynamically from external, secured enterprise knowledge bases. | Parametric Memory: Relies on static knowledge encoded within the model's neural weights. |
| Data Residency & Sovereignty | High Control: Sensitive data remains within the enterprise boundary (VPC/On-prem). | Low Control: Public LLMs require sending data to external APIs. |
| Access Control (RBAC/ABAC) | Granular: Can enforce document-level permissions at the retrieval stage. | None: The model cannot natively segregate knowledge based on user roles. |
| Data Deletion | Feasible: Data can be removed instantly by deleting from the vector index. | Difficult: Removing specific data from a trained model requires retraining. |
| Hallucination Risk | Reduced: Responses are grounded in retrieved evidence. | High: Prone to fabrication when facing obscure or private topics. |
| Auditability | High: Can provide specific citations for every claim. | Low: Operates as a "black box." |
| Security Risks | RAG Poisoning & Vector Inversion: Malicious documents can manipulate outputs. | Training Data Leakage: Model may regurgitate PII from training corpus. |
| Latency & Cost | Higher Latency/Variable Cost: Overhead from retrieval and re-ranking. | Lower Latency/High Training Cost: Fine-tuning is expensive upfront. |
