Use AI models.
Stay compliant.
ChatGPT, Claude, Gemini and more - but processed in Germany and Europe. No data transfers to the US. No training on your inputs.
Use AI. Stay compliant.
Many businesses and public institutions are not allowed to use US-based AI tools. With Vantero, you decide where your data is processed - from German servers with maximum data sovereignty to European data zones with the world's most powerful models. No compromises on privacy or performance.
Everything stays in Germany.
Data never leaves German servers. Processing exclusively in German data centres - fully anonymised, with no third-party access. Ideal for government agencies, the public sector, and organisations with strict compliance requirements.
