7-block multi-model architecture

Sovereign multi-LLM architecture.
When data sensitivity demands a compartmentalized architecture.
← Back to consulting
The context
Protected data left no room for shortcuts.
Legal data space needed a system for sensitive documents, sourced legal summaries, and data sovereignty (France only). Documents contained protected personal information, ongoing procedures, and professional secrecy.
The discussion
The flows were mapped before anything was built.
Mapped data flows and security requirements (SecNumCloud). Designed compartmentalized circuits. The system must NOT render decisions.
The solution
Two circuits never share raw data.
7-block architecture. Mistral AI handles ingestion and anonymization in SecNumCloud. Claude receives anonymized questions and produces sourced analysis. The two circuits never share raw data.
Why this level
The stakes justified the complexity.
Highest complexity, justified only for truly sensitive data, multi-step reasoning, and non-negotiable sovereignty.
In summary
Four facts tell the story.
Mistral AI + Claude
SecNumCloud, compartmentalized circuits
100% French territory
