As Europe accelerates its push towards digital sovereignty, the conversation is moving from ambition to execution.
At the upcoming Sovereign Tech Europe event, organised by Forum Europe, policymakers, industry leaders, and technology experts will come together to explore how sovereignty can be operationalised across the European landscape.
As a partner of the event, Cronos Europa will be present with multiple experts on site.
Ruben Maris, COO of De Cronos Groep, will represent Cronos Europa in the panel discussion on how sovereignty can be embedded across Europe’s public sector.
In this context, we take a step back to look at a fundamental question.
What does digital sovereignty really mean in practice?
In practice, this goes beyond infrastructure. It requires organisations to understand where control sits across their entire technology stack and how dependencies affect their ability to act.
A key misconception is that sovereignty can be achieved through a single decision. In reality, it is a layered discipline.
Ruben describes it as a four-layer model:
Each of these layers addresses a different dimension of sovereignty. Focusing on only one creates an incomplete and potentially misleading sense of control.
While data residency is important, it is also the most visible and often the easiest layer to address. It does not automatically guarantee control over how systems operate, how technology evolves, or how decisions are made.
For example, organisations may store their data in Europe while still relying on external providers for operations, proprietary platforms for core functionality, or external expertise for critical decisions.
In such cases, sovereignty is partial.
True sovereignty requires organisations to understand and manage dependencies across all layers, not only where data is stored.
Portability means the ability to move workloads, data, and systems across environments without being locked into a single provider or ecosystem.
This is particularly relevant in a European context, where organisations need to balance regulatory requirements, operational resilience, and long-term flexibility.
Without portability, even well-designed architectures can become constrained over time. Decisions that optimise for short-term efficiency may limit future options and reduce the organisation’s freedom to adapt.
Portability therefore becomes a way to maintain strategic control, but also to preserve freedom. The freedom to move, to reconfigure, and to respond to changing conditions without being constrained by earlier decisions.
European organisations have access to a growing ecosystem of sovereign technologies. However, these solutions are often fragmented.
Bringing them together into a coherent, operational stack remains difficult.
As a result, organisations may have individual components that support sovereignty, but lack an integrated approach that connects data, operations, technology, and capabilities.
This gap is not primarily technical. It is architectural and organisational. It requires clear choices, alignment across teams, and a long-term view on how systems evolve.
It starts with understanding which layer of sovereignty matters most for the organisation. For some, this may be data jurisdiction. For others, operational independence or control over technology choices.
At the same time, sovereignty is rarely a single, uniform choice. Most organisations operate in a hybrid reality, where different parts of their architecture require different levels of control.
Some workloads can run perfectly in public cloud environments and benefit from scalability and speed. Others require a more controlled setup, for example in private environments or on European technologies, depending on regulatory, operational, or strategic considerations.
Digital sovereignty is therefore not a one-size-fits-all model. It is about finding the right balance across the architecture, based on context and priorities.
From there, organisations need to define how the different layers interact and where dependencies exist.
This often involves reassessing existing architectures, identifying critical dependencies, introducing portability, and building internal capabilities over time.
Regulatory frameworks, public sector initiatives, and market dynamics are aligning around the need for greater control, transparency, and resilience.
At the same time, organisations are increasingly aware of the limitations of existing dependency models.
This combination creates an opportunity.
Organisations that act now can shape their architecture, capabilities, and partnerships in a way that supports long-term control. Those that delay may find themselves constrained by decisions that are difficult to reverse.
