In recent years, we’ve seen that new laws and regulations are placing increasingly specific requirements on ICT service providers. Consider, for example, the GDPR (which outlines tasks and responsibilities for the “processor”), the Cybersecurity Act (which mandates supply chain security and directly applies to “business-to-business ICT service providers”), and the AI Regulation (which imposes specific obligations and responsibilities on the “provider”). It’s no surprise, then, that this trend is also reflected in more and more guidelines and codes of conduct, including the Notarial Information Security Code of Conduct (hereinafter: “KNB Code of Conduct”). Given that the Royal Dutch Notarial Association (KNB) had 3.497 members at the beginning of 2025, there’s a good chance that, as an ICT service provider, you count at least one affiliated notary among your clients. This blog outlines what the Code of Conduct means for you as an ICT service provider.
