Complear OS

Complear is a European sovereign defence and AI infrastructure company building secure, on-premises intelligence systems for high-security and regulated environments. Its flagship platform, Complear OS, integrates cybersecurity operations, AI-driven threat intelligence, compliance automation, information governance, and autonomous response orchestration into a single sovereign infrastructure layer.

Unlike fragmented cloud-dependent security architectures, Complear operates entirely within the defended perimeter, eliminating foreign data exposure and external operational dependencies. The platform provides real-time security monitoring, behavioural threat detection, MITRE ATT&CK mapping, vulnerability and malware correlation, attested encryption, and automated compliance enforcement aligned with NATO INFOSEC, NIS2, ISO/IEC 27001, NIST 800-53, GDPR, HIPAA, PCI DSS, and the EU AI Act.

Complear’s infrastructure supports multi-site, multi-OS deployments across defence, healthcare, critical infrastructure, aerospace, and regulated industrial environments. The system is designed for sovereign operations where technological autonomy, resilience, and secure information governance are mission-critical.

The company’s AI governance architecture is built with human-in-the-loop accountability by design and aligns with EU AI Act Article 14 and NATO AI Principles of Responsibility.

Complear also maintains a strong post-quantum cryptography research and patent portfolio, with seven patents pending across compliance lifecycle infrastructure and post-quantum migration technologies. The company is currently engaged with the Portuguese Armed Forces, NATO-related certification pathways, and European Defence Fund initiatives supporting European technological sovereignty.

Headquartered in Portugal, Complear combines expertise across defence, military intelligence, law, cybersecurity, AI governance, and advanced cryptographic research.
