About this report
Secure military communications, cryptography, trusted digital identity infrastructure, cross-domain data exchange, and quantum-safe transition do not form a single market. They form a layered and sovereignty-sensitive capability stack in which different technologies operate under different regulatory regimes, assurance standards, certification thresholds, and degrees of direct military relevance.
The central analytical problem is therefore not to identify a generic group of European “cyber companies,” but to distinguish which firms are genuinely central in classified or defence-sensitive communications environments, which are structurally important in sovereign digital-trust architecture,…
