Cybersecurity & Sovereign Resilience

Defence forces face an increasingly contested digital landscape. From state-backed cyber actors to supply chain vulnerabilities, the attack surface is expanding — and so must the response.

Cyber resilience is the ability to maintain operational effectiveness, safeguard data integrity, and ensure mission continuity in the face of evolving threats. It means more than preventing breaches — it means operating securely under pressure, in real time, and without compromise.

Sopra Steria delivers this resilience through integrated cyber strategies, operational security architectures, and sovereign-grade implementation — proven in sensitive, high-security contexts across Europe.

Zero Trust Defence Infrastructure
We design and implement cybersecurity architectures based on Zero Trust principles — including strict access control, continuous authentication, segmentation, and behavioural analytics — tailored to classified and mixed environments.

Embedded Cybersecurity across all platforms
From SAP and Oracle to Mendix and bespoke mission systems, we secure what’s already in place. Our delivery teams include cybersecurity engineering by default — no bolt-ons, no shortcuts.

SOC Frameworks & Threat Monitoring
We support MoD entities in designing and operating Security Operations Centres — tailored to the Dutch regulatory context and NATO interoperability standards — with threat intelligence, 24/7 monitoring, and incident response readiness.

Resilience for Joint & Distributed Command
Secure interoperability is critical in coalition operations. We design architectures that maintain cyber integrity across multi-theatre environments, supporting dynamic coalition tasking and secure cross-domain collaboration.

Future-Proofed, Sovereign Security
Our solutions prioritise data sovereignty, local control, and regulatory alignment. We help the Dutch MoD develop sovereign operational cybersecurity frameworks — with no vendor lock-in and full visibility.
