Jurisdiction
Data held by US companies can be subject to US laws such as the CLOUD Act, even when it is stored in Europe. With Biberstack your contract partner is a German company without a US parent.
Hosting in Germany · Open source · EU law
Sovereign infrastructure, operated for you in Germany.
Biberstack runs Kubernetes clusters, Keycloak, servers, language models and open-source applications for companies that want to keep their data under EU law and stay independent of US cloud providers.
Hosted in Germany
Your workloads and data run on infrastructure in Germany.
German contract partner
Contracts with encircle360 GmbH under German and EU law.
Open source
Kubernetes, Keycloak and open standards instead of proprietary cloud services.
Operated for you
Setup and ongoing operation from one team.
Why it matters
Who controls your infrastructure?
Where your data lives, which law applies and how easily you can switch providers are business decisions, not technical details.
Independence
Proprietary cloud services make every switch expensive. We build on open-source software and open standards, so your setup stays portable.
Compliance
GDPR, NIS2 and industry rules ask where data is processed and who can access it. Hosting in Germany with a German partner gives you clear answers.
