Companies should assess the risk associated with individual suppliers, taking into account factors such as the sensitivity of shared data, the criticality of services, or geographic location. NIS2 encourages information sharing about supply chain threats and cooperation between organizations to jointly raise security standards. In case of incidents, companies must have response plans that also include external entities. The goal is to ensure that weaknesses in the supply chain do not become an attack vector on the organization.
What Consequences Do Enterprises Face for Non-Compliance with the NIS2 Directive?
Non-compliance with the provisions of the NIS2 directive can have serious consequences for enterprises. First and foremost, companies face severe financial penalties. For essential entities, the maximum penalty can amount to 10 million euros or 2% of total worldwide annual turnover. For important entities, the limits are slightly lower - 7 million euros or 1.4% of turnover. In addition to monetary penalties, supervisory authorities can also impose other sanctions, such as temporary suspension of certification or a ban on holding management positions for persons responsible for violations. However, consequences extend beyond legal issues. Security incidents resulting from failure to apply appropriate safeguards can lead to serious financial losses, operational disruptions, data loss, or customer privacy breaches. This in turn translates into loss of reputation, customer trust, and competitive advantage. In an era of increasing awareness of cyber threats, compliance with security standards becomes crucial for long-term enterprise success.

How Does the NIS2 Directive Change the Role of Boards and Senior Management in Cybersecurity Matters?
The NIS2 directive places cybersecurity at the center of attention for boards and senior management of enterprises. Regulations clearly indicate that responsibility for ensuring compliance with requirements lies with persons managing the organization. They must ensure implementation of appropriate policies, procedures, and technical measures, as well as allocation of adequate resources and budgets. NIS2 requires boards to regularly discuss cybersecurity issues, assess risks, and make strategic decisions in this area. Directors and managers must be aware of threats and understand the impact that incidents can have on company operations. They are expected to provide proactive leadership and promote a security culture throughout the organization. In case of violations, it is management personnel who can bear personal responsibility, including financial penalties or bans on holding positions. This approach aims to ensure that cybersecurity will be treated as a priority at the highest decision-making levels of enterprises.
What Challenges Do Enterprises Face in the Process of Adapting to NIS2 Requirements?
Adapting to the requirements of the NIS2 directive can be quite a challenge for many enterprises. One of the main problems is the complexity and dynamics of the modern IT environment.

It’s time to take on this challenge and make cybersecurity the foundation of our shared digital future.
The obligation most “ready” companies have missed
Organisations that consider themselves prepared for NIS2 have usually done the visible work: policies written, controls deployed, an incident procedure drafted. The requirement they most often have not started is supply chain security — and it is the one that cannot be completed quickly, because it depends on other companies agreeing to things.
In practice it means knowing which suppliers support a service in scope, assessing them proportionally to that role, and having security terms in the contracts that let you enforce anything at all. Each step involves a counterparty with its own timetable, so a programme that leaves this to the end discovers a dependency it cannot compress. Sequencing the supplier work early, alongside the internal controls, is part of how a NIS2 compliance programme is normally planned.
