Digital sovereignty is often discussed in terms of data and infrastructure. In practice, however, sovereignty becomes most tangible in cybersecurity.
When a threat occurs, who detects it? Who analyses it? And who decides how to respond?
As organisations increasingly rely on external platforms and security providers, these questions become critical. Cybersecurity is no longer only about protection. It is about control over visibility, response, and decision-making.
Within Cronos Europa’s Sovereign Tech series, cybersecurity represents a domain where sovereignty shifts from concept to operational reality.
We spoke with Federico Meiners, MDR Manager at ACEN, a sister company within De Cronos Groep, to explore what sovereign cybersecurity means in practice.
Sovereign cybersecurity refers to the ability of an organisation to maintain control over its security operations, including detection, analysis, and response.
In traditional models, security capabilities are often adopted without a clear understanding of where control sits and who is responsible when something goes wrong. A sovereign approach changes that starting point.
A sovereign approach focuses on:
The goal is not to eliminate external support, but to choose partners who make control explicit, visibile and measurable.
European organisations are operating in an environment shaped by increasing regulatory pressure and geopolitical complexity.
Frameworks such as NIS2 reinforce the need for accountability and resilience. At the same time, organisations are becoming more dependent on external technologies, platforms, and service providers.
This creates a paradox.
Organisations may be compliant, but still lack control over their security operations.
For example, detection capabilities may be outsourced, logs may be processed externally, and incident response may depend on third parties. In such cases, organisations rely on others to understand and react to threats affecting their own systems.
Sovereign cybersecurity addresses this by bringing control back to the organisation.
Moving towards sovereign cybersecurity requires a structured approach.
The first step is visibility. Organisations need a clear and complete view of their systems, networks, and security events. Without this, control is not possible.
The second step is clarity for detection and response. Organisations need a clear understanding of how incidents are identified, prioritised and handled, and a partner who operates those processes with full transparency.
The third step is governance. Security decisions must be aligned with organisational priorities and risk appetite, rather than being driven by external constraints.
This often leads to models where the right external partner supports security operations directly, while the organisation retains clear visibility and governance over outcomes.
Many organisations operate with fragmented security landscapes. Over time, tools and providers have been added without a unified structure, making it difficult to maintain oversight.
Dependency is another key challenge. Once critical security functions are outsourced, it becomes difficult to regain control without significant effort.
Finally, expertise remains a limiting factor. Sovereign cybersecurity requires skilled professionals who can interpret signals, make decisions, and manage complex environments.
Sovereign cybersecurity enables organisations to move from passive protection to active control.
By maintaining visibility, ownership, and governance over security operations, organisations can respond more effectively to threats and reduce dependency on external actors.
