Deloitte and STACKIT: Strengthening digital sovereignty in Europe

Combining STACKIT’s technology platform with Deloitte’s advisory and implementation expertise

Businesses and public sector organisations face the challenge of building secure, compliant and economically independent cloud and data infrastructure. This also creates the foundation for secure, scalable and trusted AI adoption.

By combining STACKIT’s sovereign cloud solutions with Deloitte’s industry expertise, we offer an integrated approach that meets the technological demands of global providers while upholding European values of data protection, transparency and control.

As geopolitical tensions and digital dependencies increase, European businesses and public institutions face growing challenges in managing data and adopting AI. Data sovereignty is becoming essential to the secure, scalable and trusted use of AI. Establishing sovereign data management within the EU is therefore a strategic priority.

Five pillars of the Deloitte and STACKIT partnership

Deloitte provides end-to-end advisory services to help clients migrate to and operate on STACKIT. Its cloud infrastructure is developed, operated and controlled entirely in Europe, making it a relevant option for organisations that require data sovereignty and regulatory assurance.

Our partnership enables tailored cloud architectures designed to support data residency and isolation requirements. These are particularly relevant for public sector organisations, financial services providers and critical infrastructure operators. Deloitte brings deep industry knowledge to help address sector-specific needs.

Deloitte advises clients on legal and regulatory requirements, from compliance with the General Data Protection Regulation (GDPR) and the EU AI Act to the development of cloud environments that are ready for audit. This helps organisations navigate an increasingly complex regulatory landscape with greater clarity and confidence.

Deloitte and STACKIT support organisations in preparing for and implementing certifications such as BSI C5, ISO 27001 and relevant industry-specific standards. This helps organisations demonstrate that their cloud solutions meet applicable security and compliance requirements.

Deloitte’s wider partner network complements its collaboration with STACKIT. Working with leading technology providers, including ServiceNow, the partnership can help create innovative solutions that go beyond cloud infrastructure to deliver broader business value.
