Building software that meets BIO2 and the Cyberbeveiligingswet.
Neyon works on European, public-sector systems where correctness, clear architecture and careful modernisation matter more than speed alone. That means being fluent in the compliance framework government organisations must deliver within — not working around it.
Reference: European vehicle-data exchange
For a Dutch government implementation agency in the mobility sector, I work on modernising a European interface architecture for cross-border enforcement of traffic offences. Part of this is an API gateway built on Microsoft YARP: a consistent entry point for services with shared capabilities for routing, security, request/response transformation and observability.
Earlier work within the same ecosystem includes a National Access Point for processing and validating standardised vehicle information (IVI/XML) and electronic Certificates of Conformity (eCoC), and secure messaging via eDelivery/AS4(Domibus, P-Modes, certificates and encryption) for cross-border vehicle re-registration within the Once-Only Technical System (OOTS).
Security isn't a layer added afterwards but part of the architecture: certificate-based authentication, mTLS, Azure Application Gateway with Web Application Firewall, container scanning, and automated code analysis (SonarQube, Fortify) in the CI/CD pipeline.
Why this is relevant
- BIO2 (Baseline Informatiebeveiliging Overheid 2) — the compliance framework Dutch government IT suppliers must demonstrably meet.
- Cyberbeveiligingswet (the Dutch NIS2 implementation) — duty of care, incident reporting and registration obligations for critical-sector organisations.
- NORA and European interoperability standards for interface architecture.
- Procurement processes at Dutch public bodies, including screening (VOG, and where applicable a security clearance).
Working with public-sector clients
Neyon contracts on its own model agreement and delivers on a project basis, with a defined scope and delivery date — not as a stand-in for a vacancy. At peak load or unavailability, Neyon brings in a trusted partner, by agreement.
