Security Division for AI, NIS2 & Operational Cyber Readiness

Systems assurance, security architecture & infrastructure defense

Formalized threat modeling, wire-level protocol dissection, and hardened distributed runtime architecture for enterprise platforms, AI clusters, and high-throughput environments:

• Offensive Security & Adversarial Threat Modeling: Cyber Threat Intelligence (CTI) mapping and structured adversarial tradecraft across MITRE ATT&CK and the Cyber Kill Chain.
• Wire-Protocol Analysis & Dissection: Raw packet inspection and protocol fuzzing across OSI Layers 2–7 for high-throughput networks and custom communication protocols.
• Kernel & POSIX Hardening: Vulnerability research, exploit surface reduction, and runtime simulation across hardened POSIX and Linux kernel environments.
• Defensive Hardening & Zero-Trust: Enterprise perimeter defense, network segmentation, fail-closed permission models, and deterministic security gates.
• Cryptographic Auditing & Supply-Chain: Tamper-evident provenance validation, cryptographic signing, and supply-chain integrity verification.
• Distributed Observability & Container Sandboxing: Telemetry pipeline engineering, time-series metrics ingestion, and hardware-assisted microVM isolation (AWS Firecracker, Linux namespace/cgroup isolation).

What we assess

We review how systems, people, AI tools, suppliers, and policies interact. The goal is not a paper-only compliance document. The goal is a factual risk picture and a prioritized remediation roadmap.

• NIS2 duty-of-care preparation, incident reporting readiness, and registration awareness
• AI tool inventory, prompt/workflow exposure, and staff behavior risk
• Data leakage paths across SaaS tools, browser workflows, file sharing, and unmanaged AI usage
• Website and app exposure basics that can create avoidable risk before a deeper penetration test

Methodology and factual basis

Assessments are aligned with practical cybersecurity and systems risk principles, including NIS2/Cyberbeveiligingswet readiness logic, risk assessment and duty-of-care preparation, incident reporting readiness, AI governance concepts, OWASP LLM risk categories, NIST AI RMF principles, MITRE ATT&CK adversarial tradecraft, MITRE ATLAS threat models, AWS Firecracker microVM isolation standards, and practical evidence documentation.

Who it is for

• Dutch SMEs preparing for NIS2 or Cyberbeveiligingswet obligations
• Eindhoven, Brainport, Noord-Brabant, Veldhoven, Helmond, Best, Geldrop, Nuenen, Son en Breugel, Tilburg, and Den Bosch companies
• High-tech suppliers, manufacturing SMEs, software companies, agencies, AI-enabled teams, and operators handling client data
• International companies adopting AI workflows and needing a sober security posture review

Important positioning

Ribbsaeter Systems provides readiness assessments, gap analysis, risk reviews, evidence packs, and remediation roadmaps. This is not a formal NIS2 certification and does not claim regulator approval unless a separate accredited partner engagement is explicitly arranged.
