Reference architectures for on-premises, private VPC, and air-gapped LLM deployment — hybrid RAG, retrieval guard thresholds, and EU AI Act governance APIs.
By DefenAi Labs Research20 Jun 2026· 12 min
## Executive summary
This whitepaper documents production-proven patterns for sovereign AI deployment using the DefenAi Labs platform portfolio.
## Architecture layers
1. **Ingest & corpus governance** — controlled document intake with classification
2. **Retrieval guard** — chunk scoring and insufficient-context refusal
3. **Policy gates** — human-in-the-loop before production answers
4. **Evidence export** — audit-ready packs for regulators
## Deployment topologies
- On-premises GPU cluster
- Private VPC with no egress
- Air-gapped lab environment
