The Illusion of Control

Let’s be honest: Do you know exactly which AI tools your employees have used today?

Many companies are responding to the AI hype with a restrictive IT policy: "ChatGPT is prohibited." The fear is understandable – sensitive customer data, strategy documents, or program code could end up in public cloud services and be used for training the models.

But the reality is different. Employees want to work more efficiently. When the official route is blocked, they use their private accounts on their smartphones or in the home office. The result is shadow IT: an uncontrolled outflow of data that you cannot see or prevent.

The risk: When data flows uncontrollably

Why is this problematic? It is no longer just about a "bad feeling", but about hard legal facts in Switzerland and Europe:

  • Training data:Public versions of LLMs (Large Language Models) use inputs by default to improve themselves. Your internal meeting notes could theoretically appear in a future response for another user.
  • Legal minefield (Switzerland & EU):

    • Data protection:Both the Swiss Data Protection Act (revDSG) and the EuropeanGDPRrequire control over personal data. Uploading to a US cloud without a valid data processing agreement (DPA) is a direct compliance risk.
    • EU AI Regulation (AI Act):The new European legislation demands transparency and governance in the use of AI. The use of "shadow AI" through private accounts evades any documentation and risk assessment – a violation that can be costly for companies with EU customers.
  • Loss of Intellectual Property (IP):Intellectual property leaves your protected area. Once trade secrets land in a public AI, you effectively lose sovereignty over them.

The solution: "Enablement" instead of prohibition

The most innovative companies do not ban AI – they provide a secure, internal alternative.

Imagine your team having access to the same intelligence as GPT-4 or Claude 3, but in a contained environment:

  1. No training:The AI models operate in "Inference-Only" mode. Nothing is learned, nothing is stored.
  2. Sovereign data management:The user interface and databases are located on servers in Switzerland – the secure data vault for Swiss and EU companies.
  3. Central management:You can see who uses which models and when, and have full cost control.
