European Enterprises Shifting Kubernetes On-Prem as Data Sovereignty Pressures Mount

Sidero Labs to showcase strategies for air-gapped, resilient Kubernetes infrastructure at Open Source Summit EU 2025

Amsterdam – August 25, 2025 – Sidero Labs, delivering solutions that reduce friction in managing Kubernetes and containerized applications, today reported growing demand across Europe for fully air-gapped and sovereign Kubernetes infrastructure that avoids reliance on U.S.-based cloud control planes. The company will be at Open Source Summit Europe to discuss how customers across the continent are using its solutions for secure and efficient Kubernetes management.

As European businesses prioritize data sovereignty and infrastructure control, Kubernetes adoption is moving on-premise at an accelerating rate. While Kubernetes has long been used to bridge cloud and on-prem environments, many EU organizations are now flipping that model and treating on-prem as the default, with cloud as the optional extension. From financial institutions tightening data residency enforcement to European rail systems rearchitecting infrastructure for operational continuity, organizations are rethinking where Kubernetes control lives and how infrastructure should be managed at scale.

“Sovereign control over infrastructure is becoming a top priority for European enterprises,” said Sean Saperstein, Head of Sales at Sidero Labs. “We’re helping organizations eliminate external dependencies, simplify bare metal operations, and secure their infrastructure at the operating system level, whether they’re running in central data centers or remote air-gapped environments.”

Sidero Labs’ technologies are built specifically for these scenarios. Talos Linux, the open source Kubernetes-optimized operating system, replaces traditional OS complexity with a declarative, API-driven model that eliminates SSH and reduces the attack surface. Talos makes it easy to enforce consistency across nodes, including in environments with strict compliance or no internet access. Paired with Omni, Sidero’s SaaS platform for multi-cluster Kubernetes management, organizations can automate cluster lifecycle operations at scale without introducing centralized control plane dependencies that violate data sovereignty goals.

At Open Source Summit Europe this week, Sidero Labs will highlight new patterns for managing Kubernetes in sovereign and offline environments, including insights from real-world deployments across the continent. Attendees will learn how emerging open source tools and management models are helping teams simplify operations and assert full infrastructure control outside of cloud dependencies.
