Cybersecurity is no longer just an IT issue, but a responsibility at management level. The arrival of the European NIS2 Directive (Network and Information Security Directive 2) heralds a new era of responsibility. Whether you are active in healthcare, logistics, energy, or manufacturing, NIS2 means that you must be able to demonstrate that your security is in order, otherwise there could be serious consequences.

The new rules may seem like yet another obligation, but they also offer opportunities. Opportunities to use data and intelligence to build real resilience. And that is precisely where Altares Dun & Bradstreet can make a difference.

What is NIS2? A brief explanation

NIS2 is the updated European cybersecurity law (Directive (EU) 2022/2555). It replaces the original NIS Directive from 2016 and significantly expands its scope. The aim is to better protect Europe's digital infrastructure, from energy grids to cloud services, against cyberattacks. The directive distinguishes between essential and important entities. Essential entities are organizations in sectors such as energy, healthcare, transportation, drinking water, digital manufacturing companies, food and waste workers, postal and courier services, and research institutions. In practice, most medium-sized and large organizations in these sectors fall under NIS2. Smaller companies may also be covered if they provide critical services to these sectors.

What exactly does NIS2 require?

Organizations must be able to demonstrate that they actively manage their cyber risks. The directive stipulates that companies must take appropriate technical and organizational measures, such as encryption, access management, and secure software development. Serious incidents must be reported within 24 hours, followed by a supplementary report within 72 hours and a final report within one month.

In addition, companies must identify and manage cyber risks in their supplier and partner networks. Management is ultimately responsible for the policy and can be held liable if the organization fails to comply. Regulators can impose heavy penalties of up to €10 million or 3% of global annual turnover.

The situation in Belgium

Belgium was at the forefront of the introduction of NIS2. The law has been in effect since October 18, 2024, replacing the previous Cybersecurity Act. Belgian organizations must be able to demonstrate that they have taken the appropriate measures and prepare for audits by the Centre for Cybersecurity Belgium (CCB). The Belgian regulator expects organizations not only to comply with legal obligations, but also to demonstrate that they are working on continuously improving their cyber resilience and supply chain management.
