About & Leadership

Two decades of CISO practice, engineered into autonomous AI

Cyberium Limited is a London-based cyber and AI-security company. We build NEXUS, an AI-driven framework that industrialises security governance and orchestrates AI agents under human command, for governments, law enforcement and global enterprises.

The company

Why Cyberium exists

Regulated organisations face a widening gap: threats move at machine speed, while governance, audit and accountability still move at human speed. Cyberium closes that gap. NEXUS lets AI agents carry the technical load while humans keep command, control and compliance posture, so the CISO function can finally scale.

AICA, the cyber-intelligence agency

AICA, the Artificial Intelligence Cybersecurity Agency, is Cyberium's cyber-intelligence business unit. It fuses OSINT and dark-web data into a structured knowledge graph of companies, boards, investors and exposure, then turns that data into worldwide intelligence benchmarks that steer, or reverse, high-stakes decisions.

Aim

Establish the bases of intelligence: scope, sources, logic and hidden information, mapping the battleground of top companies per industry and country into a single reference hypercube.

Train

Collect information across web and dark web with a defined time depth, organise it as documents in a NoSQL repository, and build the relationships that turn raw data into intelligence.

Shoot

Deliver worldwide intelligence benchmarks with historical depth, rebuilding ownership, relationships, financials and exposure across the timeline to support, or revert, decisions.

CyberMetrics™

Risk BI suite for quantitative and qualitative risk assessment, dynamic dashboards, sectoral benchmarking and AI prioritisation of remediation by business impact, with predictive identification of emerging vulnerabilities.

ComplianceTracker™

Compliance assessment tool: automated mapping of NIS2, DORA, GDPR and EU AI Act requirements, maturity indicators, remediation plans and reports tailored for regulators and management.

ThreatMapper™

Threat-modeling solution powered by the AICA DB, continuously updated with sector-specific attack vectors, and AICA's proprietary AI core and agents.

Product lines span the full cycle: SCOUT, STRESS, ASSESS and ADDRESS, from external exposure scouting to board-grade remediation economics.

Raffaele Di Marzio

Founder & Architect of NEXUS
24+ years ISO 27001 Lead Auditor PhD Physics Patent pending

Author, architect and editor of the NEXUS framework, Raffaele brings 24 years of experience in cybersecurity and AI security, with recent focus on securing AI products in regulated banking environments. His vision spans cyber, risk and information-system security, extended to the specific risks of ML / LLM / RAG models and AI agents, and to AI governance, NIST AI RMF, MITRE ATLAS, OWASP LLM Top 10, ISO 42001 and the EU AI Act.

He has held CISO and Deputy CISO roles in banking (Dexia, BNP Paribas, Crédit Agricole, AXA, Crédit du Nord), familiar with DORA, NIS2 and GDPR compliance and the anticipation of the AI Act. He bridges deep technical requirements, security architecture, threat modeling, secure coding, DevSecOps and MLSecOps, with the political stakes of governance before the COMEX, the Risk Directorate and audit.
