Security Architecture Built for European Defence
Sovereign cloud infrastructure with controls designed to satisfy the most demanding European and NATO security requirements. Each deployment operates within EU jurisdiction under your national security authority's oversight.
The Reality of Defence Data Security
Defence and security operations generate and process some of the most sensitive information in existence. Operational plans, intelligence assessments, force dispositions, classified communications, this data demands protections that exceed typical enterprise security by orders of magnitude.
Monthly cyberattack attempts on defence organisations
EU member states requiring sovereign data controls
NotPetya estimated global impact
The European Commission's cybersecurity assessment revealed that defence-related organisations face an average of 1,500 cyberattack attempts per month, with state-sponsored actors specifically targeting military cloud infrastructure. The NotPetya attack that disrupted NATO logistics operations cost an estimated EUR 10 billion globally. When military cloud services operate across national boundaries, the attack surface multiplies and the stakes become existential.
Argus was architectured with classified-grade security as the foundation, not retrofitted as an afterthought to satisfy procurement requirements.
Your Sovereign Deployment, Your National Security Authority
Every Argus deployment is provisioned as an isolated sovereign environment within EU jurisdiction, under your national security authority's governance framework.

Your Path to Accreditation
National Data Sovereignty
Your operational data never leaves your designated EU jurisdiction. Per-nation organisational isolation (organization_id enforcement), cryptographic tenant separation, and EU-only infrastructure ensure that classified and sensitive defence information remains under your national authority's control.
Your Security Accreditation Authority
You maintain full authority over security accreditation through your national security authority (NSA). We implement the technical controls required by EUCS, NIS2, ISO 27001, and EUCI standards. The security architecture meets OWASP ASVS Level 2 requirements. Because each deployment operates under your sovereign control, the accreditation decision remains yours.
Why This Matters for Defence
Defence accreditation requirements vary by nation and classification level. Your national security authority may impose requirements beyond baseline EU standards. Multi-national operations require demonstrated compliance across multiple frameworks simultaneously. With Argus, you have the technical foundation for accreditation at any level, from EU RESTRICTED to national SECRET equivalents.
European Security Framework Compliance
Argus implements the technical controls required by European and NATO security frameworks. Here's our alignment with each standard your organisation may need to satisfy for defence operations.
Defence-Grade Security Controls
Beyond compliance frameworks, here's what protects operational data at every layer of the platform.
Military-Grade Encryption
Data at rest protected with AES-256 encryption. Data in transit uses TLS 1.3 with perfect forward secrecy. Post-quantum cryptography (PQC) readiness for future-proof protection against quantum computing threats.
Zero-Trust Architecture (ACP 240)
Every request is authenticated and authorised regardless of network location. Aligned with NATO ACP 240 zero trust principles and reconciled with Data Centric Security per STANAGs 4774, 4778, and 5636.
National Sovereign Isolation
Each nation's deployment is cryptographically isolated from all others. Per-nation organization_id enforcement, row-level security policies at the database engine level, and dedicated encryption keys per sovereign instance.
Tamper-Proof Audit Logging
Every security-relevant event logged to append-only storage with cryptographic integrity verification. Aligned with EUCI accountability requirements. Full audit trail for security accreditation evidence.
Operational Threat Detection
Behavioural analytics monitor for anomalies: unusual access patterns, queries outside operational parameters, bulk data access attempts. Automatic alerts and access suspension for security investigations.
Supply Chain Assurance
Continuous monitoring of all dependencies for known vulnerabilities. SBOM generation and verification. Content Security Policy and Trusted Types. Open-source commitment ensures full supply chain transparency, no vendor lock-in.
Sovereign European Cloud Infrastructure
Your Argus deployment runs on sovereign European cloud infrastructure designed for defence workloads.
EU Data Residency
Data processing and storage configurable to specific EU member states. National data residency enforcement ensures operational data never leaves your designated jurisdiction.
Physical Security
Infrastructure facilities implement physical access controls, environmental protections, and operational procedures meeting European defence security standards.
Network Defence
DDoS protection, web application firewalls, and network segmentation protect against external threats. Air-gapped deployment options available for classified environments.
Operational Continuity
Autarkic operations capability enables continued function during disconnected, intermittent, and limited (DIL) conditions. Graceful degradation ensures mission continuity even when connectivity is compromised.

How Security Accreditation Works
Security accreditation for defence systems is a shared responsibility between the platform provider and the deploying organisation's national security authority.
What We Provide
- Technical controls aligned with EUCS, NIS2, and EUCI requirements
- Operational procedures implementing European security standards
- Documentation mapping capabilities to framework controls
- Technical support for national security accreditation processes
- Infrastructure within accredited EU sovereign facilities
Your Authority's Responsibility
- Pursuing formal accreditation through your national security authority
- Implementing organisational security policies beyond technical controls
- Personnel security clearances and governance structures
- Maintaining operational security disciplines over time
Why This Matters
When evaluating cloud services for defence operations, verify what specific accreditation has been achieved and by which authority. EUCS certification is granted by national certification bodies. EUCI handling authorisation is granted by the relevant Security Authority. A vendor's certification in one jurisdiction doesn't automatically extend to yours.
Argus is built so that your path to security accreditation is as straightforward as possible. When your national security authority evaluates the platform, they won't find technical gaps requiring architectural rework. The sovereign foundation is ready.
Security That Enables Operations
Defence security controls designed to work with how military and intelligence operators actually operate, not to create obstacles that compromise mission effectiveness.
Federated Identity
National eID integration. Your clearance credentials. Cross-border identity via eIDAS.
Tactical Edge Security
Same protection at the tactical edge. Autarkic mode for DIL conditions.
Operational Speed
Security processing in milliseconds. No workflow delays at battle rhythm tempo.
Adaptive Session Control
Classification-aware session management. Timeouts adapted to operational tempo.
Security only works if it enables rather than hinders operations. These controls are designed to be invisible during normal operations while remaining absolutely effective at protecting sovereign information.
