multi-domain operations (command & control)

Real-time coordination of land, air, sea, space, and cyber operations through integrated C2 systems. As an integrator system, we deliver command centres, tactical data links, simulation systems and interoperability solutions enabling seamless allied coordination (NATO TIENCIA exercises participant). Our CENTERIS solution combines the CRIMSON C2 platform with data-centric security, enabling multinational operations whilst managing information confidentiality for each nation.

cyber defence & intelligence

Protecting critical communications and data from strategic to tactical levels. We deploy data-centric security (DCS) architectures, post-quantum cryptography, trusted AI systems maintaining human oversight, and secure collaborative platforms for classified information sharing across allies. Our capabilities are strengthened by our subsidiary, CS Group, whose defence-grade systems and sovereign space technologies extend our reach from terrestrial to orbital operations. Virtual GEO, Europe's only sovereign Earth Digital Twin, ensures complete data sovereignty for cartography-centric defence operations.

mission support & resilience

Ensuring operational readiness through maintenance optimization, supply chain digital transformation, training & simulation environments combining virtual and physical exercises, extended reality solutions for mission rehearsal, and fleet management systems maximizing equipment availability.

From reactive to proactive: Europe's strategic shift in Cyber Defense

enforcing Europe's digital defence sover

1. anticipating threats before they materialise

We develop systems that detect, analyse, and neutralise risks before they impact operations through multi-source intelligence fusion and predictive analytics.

2. secure critical communications and data

From post-quantum cryptography to trusted AI, our teams ensure sensitive information remains protected across all classification levels and operational environments.

3. enable seamless allied interoperability

Multi-domain operations require coordination. Our platforms & Tactical Data Links capabilities connect forces across land, air, sea, space, and cyber domains whilst maintaining security sovereignty.

4. accelerate decision-making cycles

Real-time intelligence fusion and AI-powered analysis help commanders act faster with better information, maintaining operational advantage.

5. strengthen European digital sovereignty

As an independent European player, we provide credible alternatives to global tech monopolies through sovereign solutions whilst ensuring democratic oversight and ethical AI standards.

6. defending the information domain

Through Cercle Pégase and the combined expertise of Sopra Steria and CS GROUP, we help defence and institutional actors anticipate, detect and counter influence operations.

multi-domain operations (M2MC)

Command and control across all domains

virtual GEO

Our sovereign 3D mapping engine equivalent to Google Earth, providing complete data sovereignty for cartography-centric defence operations. Fully developed and maintained in France.

post-quantum cryptography

Rolling out quantum-resistant encryption across defence networks before quantum computers threaten current systems. Active migration planning with Cryptonext Security partnership.

trusted AI implementation

Deploying AI systems that maintain human oversight whilst accelerating decision-making. Member of the Confiance.ai collective developing European AI standards and Franco-German trusted AI label.
