NEXOVA GROUP LIMITED

What NEXOVA GROUP LIMITED does

Nexova Group SA is a Belgian cybersecurity engineering firm headquartered in Transinne (Libin), Belgium, delivering cyber resilience solutions to European defence, space, and critical infrastructure operators. Its core offering is the proprietary CITEF (Cyber Integration, Test and Evaluation Field) digital twin and cyber-range platform, which creates virtual replicas of IT/OT environments to support training, security testing, architecture validation, incident response rehearsal, and R&D. The platform is anchored by a €20 million, 3,300m² Cybersecurity Centre of Excellence with SOC, training rooms, technology labs, and classified facilities, and has been selected to underpin the €60 million European CITADEL Range project.

The company monetises through four service modules layered on CITEF: 24/7 Cybersecurity Managed Services (SOC, EDR/NDR, threat hunting, incident response), Cyber Academy training (executive briefings and hands-on technician training), strategic Consulting (NIS2/DORA/CRA compliance and cyber resilience roadmaps), and Tailored Engineering Solutions (custom SOC builds, training labs, and digital twins). Enabling technologies — AI/ML for threat detection and generative scenario simulation, Quantum-Safe Communications (QKD and post-quantum encryption), and Model-Based System Engineering — extend the platform surface. Pricing is quote-based and customised per engagement, delivered on-premise or as managed services.

Nexova's go-to-market is enterprise field sales targeted at European public-sector and sovereign buyers, including the European Space Agency, EUMETSAT, the Belgian Ministry of Defence (8-year Cyber Force strategic partnership), and Belgian public institutions via the IDELUX framework. The firm operates alongside sister company Starion Group under the combined 'Starion and Nexova Group' umbrella (~700 specialists across nine European countries), and was acquired by Sopra Steria Group on 30 April 2026, integrating Nexova into Sopra Steria's cybersecurity business line to scale sovereign European cyber capabilities.
