How sovereign and future-proof is your IT really? In a volatile world, theoretical exit strategies are no longer sufficient protection. One-sided dependencies jeopardize your value creation – often overnight. Become independent: STACKIT offers you genuine enterprise-level capability.
STACKIT. Your European hyperscaler.
As a European hyperscaler - recognized by SAP as a suitable infrastructure platform for RISE with SAP - we operate our infrastructure exclusively in European data centers without being subject to the US CLOUD Act. Certifications under the international ISO 27001 standard as a fundamental security framework, along with the BSI C5 Type 2 attestation building upon it and GDPR compliance, form the verifiable foundation for data storage that meets European legal requirements.
We scale with confidence across all dimensions. Our cloud platform has been proven in the Schwarz Group’s day-to-day operations with KRITIS-relevant workloads and is highly resilient. Whether high-performance SAP environments, modern cloud applications, or data-intensive AI applications: Thanks to a vendor-neutral, cloud-native architecture, you can develop and operate your applications with a high degree of flexibility, security, and resilience. STACKIT offers high portability, open standards, and elastic scaling while maintaining full control over your data within the European legal framework.
Unmatched hyperscale power for your digital future.
Thanks to our European ownership structure, we operate in accordance with European law and are not subject to the US CLOUD Act. Compliance scales reliably with every growth step: New instances inherit the strictest security standards. Certifications in accordance with the international ISO 27001 standard serve as a fundamental security framework on which the BSI C5 Type 2 certificate and GDPR compliance are based. Operation is carried out by personnel from the EU - for operational autonomy in the event of an emergency.
Secure strategic freedom - without classic vendor lock-in. For us, sovereignty is not a selectable add-on, but an elementary architectural principle. The foundation of our platform is based on open, globally established industry standards such as OpenStack and Kubernetes. In this way, we avoid structural dependencies and enable technological portability. This means strategic freedom: you can grow without being tied to a vendor and control your workloads independently at all times.
We enable enormous scalability for highly complex SAP S/4HANA landscapes. As an officially recognized infrastructure platform for RISE with SAP, we are a driving force in the market—and bridge the gap toward structural and demonstrable European sovereignty.
This official “seal of approval” from SAP confirms that we meet the extreme performance and availability requirements for business-critical core systems at a true hyperscaler level. In doing so, we demonstrate scalability (scale-up) for performance-intensive ERP environments and offer European companies the long-awaited, sovereign, and highly available alternative for their core transformation.
Digital sovereignty is often used as a buzzword - for STACKIT, it is at the heart of everything we do. We understand sovereignty as the sum of technological independence, high resilience and objective auditability. To ensure that you retain full control over your data and processes, we have our infrastructure assessed according to the strictest European criteria. The following milestones and standards underpin why STACKIT is setting the new European hyperscaler standard for true digital independence:
STACKIT demonstrates technological capability and independence every day through its high-performance architecture. This quality has also impressed the highest European authorities: STACKIT has won the contract for the European Commission’s “Sovereign Cloud” tender (with a budget of up to 180 million euros). With its classification at the high SEAL-3 level (Digital Resilience), the EU officially confirms that we are a strong and reliable partner whose infrastructure is demonstrably immune to supply chain disruptions and extraterritorial access.
With the European Sovereign Stack Standard (ES³) program, Schwarz Digits counters vague marketing promises with objective metrics. The program translates the sovereignty of entire IT infrastructures—with the cloud at their core—into measurable maturity levels (Sovereignty Maturity Levels 1 through 4). The framework makes our core message measurable for your entire IT landscape: Based on our open-source backbone, the BSI C5 certification, and “Confidential Computing,” we establish hard, objective evaluation criteria for true independence.
Analyst rankings are one of the most important benchmarks for IT decision-makers. In the report “The Forrester Wave™: Sovereign Cloud Platforms, Q2 2026,” STACKIT was recognized as a “Strong Performer.” For us, this listing is strong external evidence that our open architecture represents a serious and high-performing sovereign alternative in a direct international comparison.
We validate innovations in our own high-load operation before they are launched on the market: As part of the Schwarz Group, we are our own most demanding customer. With millions of transactions every day for almost 600,000 employees and thousands of branches worldwide, we operate a highly critical infrastructure for the European real economy. Rely on a cloud platform that reliably proves its high technological performance and scalability every day in global trade.
