Cybersecurity is often framed as a technical challenge. In reality, it is increasingly becoming a question of dependency.
European organisations rely heavily on external platforms, tooling, and security ecosystems. While these solutions offer scale and efficiency, they also introduce a structural question.
What happens when critical security capabilities are no longer under your control?
Within Europe’s broader push for digital sovereignty, cybersecurity is emerging as a key domain where dependency needs to be understood and managed.
We spoke with Wouter Decruy, Managing Partner at ACEN, a sister company within De Cronos Groep, to explore how organisations can approach this challenge in practice.
Over the past decade, organisations have adopted increasingly integrated security platforms.
Detection, monitoring, identity, and response capabilities are often bundled within a limited number of ecosystems. This creates real operational value, but only when those ecosystems operate transparently, within a trusted context, and with full visibility for the organisations they serve.
Dependency can limit visibility into how systems operate. It can reduce flexibility in adapting architectures. And it can create constraints when regulatory, operational, or geopolitical conditions change.
At the same time, European initiatives are placing greater emphasis on control, resilience, and accountability. This creates a tension between efficiency and sovereignty.
Reducing dependency does not mean abandoning existing technologies.
Instead, organisations need to take a more deliberate approach to how security capabilities are structured.
This starts with understanding where critical dependencies exist. Not all components have the same impact. Some can be externalised without risk, while others require stronger control.
From there, organisations can introduce architectural choices that increase flexibility. This may include separating detection from response, and ensuring that data and decision-making remain accessible.
The objective is not to replace one system with another, but to regain optionality.
Interoperability is often discussed in terms of data exchange, but it is equally relevant in cybersecurity. Organisations need the ability to integrate different tools, platforms, and capabilities without being locked into a single vendor ecosystem.
This is particularly important in Europe, where collaboration across institutions and Member States is essential. A sovereign approach to cybersecurity therefore requires architectures that support interoperability, both technically and operationally. This ensures that organisations can evolve their security landscape over time, rather than being constrained by past decisions.
Sovereign cybersecurity is not about isolation. It is about resilience.
Organisations that understand and manage their dependencies are better positioned to adapt to change, respond to incidents, and maintain control over their security posture.
Within Cronos Europa, we see cybersecurity as a strategic layer of sovereignty.
