Digital sovereignty determines how resilient your IT strategy remains in dynamic conditions. Whether it's cloud strategy, identity management or data usage, companies need to reassess their technological control capabilities. On this it-sa 365 topic page, you will find well-founded classifications, concrete approaches and practical ideas for a resilient, future-proof security architecture.

Digital sovereignty describes the ability of organisations to operate their IT infrastructure, data, identities and software in a controllable, adaptable and legally compliant manner. It includes, among other things, sovereignty over data and encryption, freedom of choice among technology providers, transparency in software supply chains, and independent identity and access control based on open standards.
It is not about complete independence from technology providers. In a networked world, that would be neither realistic nor economically viable. What is crucial is the ability to adapt technological decisions even when regulatory, geopolitical or market conditions change.
In the European context, digital sovereignty is also a strategic location issue. The aim is to secure critical value chains, make dependencies transparent and strengthen innovation capacity in the European single market in the long term – through clear standards, resilient architectures and regulatory stability.
Those who operate irreplaceable systems, cannot control data access or tie business-critical processes to individual platforms lose strategic room for manoeuvre. Digital sovereignty is therefore an instrument of modern risk prevention. It protects against technological dead ends, regulatory conflicts and geopolitical dependencies, making it a key success factor for resilient IT strategies.
From a technological perspective, digital sovereignty is based on four key areas of action. Only those who consistently control and secure infrastructure, software, identities and data can minimise risks, ensure compliance and remain capable of acting.
Whether strategic management, operational implementation or regulatory responsibility: digital sovereignty is not an isolated IT issue. It affects decisions at management level as well as architecture, operational and compliance issues.
It is crucial to identify the relevant dependencies within your own area of responsibility and to reduce them in a targeted manner. You can find best practices for each area in this article.
(e.g. CIO, CDO, management)
Focus: Resilience, investment protection and controllability
Digital sovereignty is a strategic risk management tool. It protects against uncontrollable cost increases, geopolitical influences and technological dead ends.
Key questions in this area are:
Possible courses of action are:
(e.g. IT architects, administrators, SecOps)
Focus: Control, transparency and technological capability
Sovereignty is reflected in the architecture. Systems must be traceable, migratable and auditable – especially in security-critical areas.
Key questions in this area are:
Possible courses of action are:
(e.g. regulations, public sector, KRITIS)
Focus: Legal certainty, transparency and social responsibility
Digital sovereignty is a prerequisite for regulatory stability and government capacity to act in the areas of compliance, the public sector and critical infrastructure. European regulations such as NIS 2 and the Cyber Resilience Act require traceable, controllable and resilient IT structures. Transparent supply chains, auditable systems and sovereign procurement strategies are thus becoming strategic cornerstones of modern administration.
Key questions in this area are:
Possible courses of action are:

Digital sovereignty is not achieved through strategy papers, but through architectural decisions. The following measures help to systematically reduce dependencies and make security risks manageable.
Document and simulate exit scenarios for business-critical cloud services on an annual basis. Be aware of migration duration, costs, technical hurdles and security risks before a change is forced upon you. Exit capability is a security feature.
What role does the European cybersecurity marketplace play in resilience, competition and cloud independence? This session provides first-hand insights.
A Software Bill of Materials (SBOM) provides transparency about the components used and dependencies. In the context of the EU Cyber Resilience Act, it is increasingly becoming a regulatory standard. Only those who know their software supply chain can quickly and confidently fix vulnerabilities.
Utilise cloud infrastructures, but retain control over cryptographic keys (Bring Your Own Key). Without control over your own keys, there is effectively no complete data control.
Central identity providers can become a single point of failure. Hybrid IAM architectures with local fallback – especially for administrative access – ensure operational capability even in the event of failures or political restrictions.

When making new purchases, rely on interoperable standards such as OIDC or S3-compatible APIs. Open interfaces increase portability, reduce lock-in risks and strengthen long-term security architectures.

Europe is increasingly becoming a global trendsetter for cyber resilience, data protection and secure digital infrastructures. Organisations that embrace European standards, transparent supply chains and sovereign architecture principles at an early stage not only ensure compliance, but also long-term innovation and competitiveness.
Digital sovereignty is therefore not just risk prevention – it is strategic positioning in the European market.
