Verifiable trust infrastructure designed for defence environments

Defence and security organisations require trust infrastructure that operates without central authority dependency, preserves data sovereignty across national boundaries, and functions in classified-adjacent environments. This architectural approach is designed for those requirements.

Discuss defence trust infrastructure

Defence organisations face three converging requirements: data sovereignty across multi-nation operations, secure communication in classified-adjacent environments, and interoperability between allied forces without creating centralised dependencies. Decentralised trust infrastructure -- where cryptographic verification operates at every organisational boundary -- is architecturally suited to these requirements. The same approach proven at scale in Swiss healthcare applies to defence communication, coalition data exchange, and sovereignty-preserving interoperability.

Regulatory drivers

NATO/EU Data Sovereignty

Multi-nation defence operations require trust infrastructure that preserves national data sovereignty while enabling verified communication between allied forces and institutions.

27 EU + 31 NATO member states with interoperability requirements

PESCO Cyber Capabilities

Permanent Structured Cooperation projects across EU defence focusing on cyber resilience, digital sovereignty, and the European Defence Technological and Industrial Base.

75 collaborative PESCO projects across EU defence

Cyber Resilience & Defence Supply Chains

Critical infrastructure protection extending to defence supply chains, requiring verifiable communication in classified-adjacent environments without centralised trust dependencies.

Solution overview

Verifiable trust infrastructure designed for defence environments means communication between organisations carries cryptographic proof of origin, integrity, and authorisation -- without depending on a central trust authority that could be compromised or operate outside national jurisdiction. This architectural capability preserves sovereignty by design: each participating organisation manages its own cryptographic identity while the infrastructure enables verified communication across boundaries.

Proven at scale

Healthcare proved the architecture at scale. HIN -- operator of Switzerland's health information network -- processes over 800,000 verified messages per month through 850+ gateways serving 30,000+ healthcare institutions. The architectural properties that make this work -- decentralised key management, no single point of failure, sovereignty-preserving trust -- are the same properties that defence environments require for multi-nation interoperability.

Healthcare and defence share a fundamental architectural requirement: trust must operate across organisational boundaries without creating centralised dependencies. The infrastructure does not change -- the security context does.

Team voices

We designed this architecture for environments where trust cannot depend on a single authority and data sovereignty is non-negotiable. Defence is the ultimate test of that principle -- every participating nation must retain control of its own cryptographic identity.
