CLASSIFIED CASE STUDY

The β€œAir-Gap” Solution:
AI Without the Internet.

We deployed a private neural network for a multinational defense contractor, allowing them to use Generative AI on classified data with zero exfiltration risk.

1. The Challenge

The β€œAir-Gap” Dilemma

Engineering teams needed AI to parse decades of technical specs β€” but security policy forbade external model access. The result: shadow IT, risk, and stagnation.

The Blockade

CISO banned ChatGPT/Copilot β€” no proprietary data in public training loops.

Shadow IT Risk

Engineers used personal devices to bypass firewalls β€” creating unmonitored data leaks.

The Data Silo

40 years of blueprints & specs sat in cold storage β€” unsearchable, unusable.

2. The Solution

The β€œSovereign Brain”: Fully On-Prem, Air-Gapped, Self-Owned

1. Hardware Architecture

We moved the compute to the data β€” no cloud, no egress.

2. Private Knowledge Graph

RAG over 4M internal documents β€” no hallucinations, only verified sources.

  • Milvus vector DB, hosted on-prem
  • Full-text + semantic search across PDFs, CAD, legacy code

3. Secure Stack Integration
