Services

Offline LLMs
Privacy-Compliant AI in Your Infrastructure

We set up standalone, isolated AI language models directly within your infrastructure, without sending data to external cloud services or big tech. You benefit from modern AI while meeting the strictest data protection and compliance requirements.

Self-hosted

No cloud dependency

GDPR-compliant

Data stays in-house

Full control

Service overview

Our services
in detail

From the self-hosted LLM environment to secure operation, AI that never leaves your house.

Self-Hosting

Building self-hosted LLM environments

What this service is

We install and configure powerful language models directly in your infrastructure, e.g. with Ollama, LM Studio or comparable platforms.

Why this matters

External AI services such as OpenAI or Claude send your data to third-party servers, a significant compliance and data protection risk, especially with sensitive business or personal data.

What’s included

  • Selection of suitable open-source models
  • Installation on your own hardware or private cloud
  • Configuration for performance & resource usage
  • Optional GPU acceleration

Your concrete benefit

✓Data never leaves your house
✓Independence from big tech
✓Predictable operating costs
✓Full model control
Data security

Maximum isolation & data security

What this service is

We configure the offline environment for maximum isolation, without external APIs, with clear access and network boundaries.

Why this matters

Without proper isolation, gateways for data leakage and uncontrolled access emerge, a risk for data protection and audits.

What’s included

  • Network isolation & air-gap options
  • Role & access concepts
  • Encryption of sensitive data
  • Audit & logging capability

Your concrete benefit

✓GDPR-compliant without external dependencies
✓Demonstrable data security
✓Protection against data leakage
✓Meeting regulatory requirements
Integration

Integration into existing systems

What this service is

We connect the self-hosted AI to your existing system landscape, entirely without external cloud APIs.

Why this matters

AI without integration stays isolated and creates extra effort instead of value. External API connections would cancel out the data protection advantage.

What’s included

  • Internal APIs & interfaces
  • Connection to documents & knowledge bases
  • Secure on-premise integration
  • Interfaces to CRM, ERP & business systems

Your concrete benefit

✓AI where the work happens
✓No media breaks
✓Full data protection advantage retained
✓Faster processes
Operations

Monitoring & operation of the offline infrastructure

What this service is

We take over monitoring, maintenance and stable operation of your offline AI environment.

Why this matters

Without professional operation, models become outdated, errors go unnoticed and availability remains uncertain.

What’s included

  • Monitoring of load & availability
  • Model updates & versioning
  • Backup & recovery
  • Support & maintenance

Your concrete benefit

✓Stable day-to-day operation
✓Up-to-date models
✓Predictable availability
✓Long-term independence

Who for

Would this pay off for you?

45 minutes, free of charge. One workflow, three numbers, an honest calculation. If it does not pay off, we say so.

Objections

What you are wondering now

What exactly does offline mean?
The language model runs on a machine in your house or on your own server. No request goes out, not even an encrypted one. That is a difference from providers advertising servers located in Germany: there, your request still leaves the building.
What hardware do we need for it?
That depends on the model and on how many people work with it at once. For ordinary office tasks it is usually considerably less than people expect. The specific recommendation comes out of the check, not out of a spec sheet.
Are open models worse than the well-known services?
For some tasks yes; for many office tasks the difference is smaller than the trouble a professional confidentiality duty otherwise causes. We pick the model for your task, not from a leaderboard.
Can we switch the AI part off again later?
Yes. Without a key configured it does not exist, and the workflow carries on as before. We build nothing you cannot get back out of.
