Five deployment modes: from local to air-gapped.

Deployment modes

Choose the right deployment model for your risk profile.

From fully local processing to controlled cloud access — start with a pragmatic setup and evolve toward stricter or broader models as your AI usage scales.

Maximum control for sensitive AI usage.

A model inside your own environment answers every request. Cloud models and external services such as web search stay off until you explicitly enable them. Best for strict data-sovereignty and confidentiality requirements.

Best fit

  • Highly sensitive business data
  • Legal, healthcare, finance, defense, regulated sectors
  • Internal knowledge assistants
  • Confidential document analysis

Hosting & evidence

Where BRANE runs when it does not run at your site.

BRANE usually runs on hardware at your site. For the hosted variant BRANE Cloud (coming soon) and for our fleet management and updates we use data centres in Germany. The evidence below belongs to the operators of these data centres, not to AI-Z. Each item links the operator's own document.
