NIS2 Directive: Anticipate risks and secure your critical infrastructures
The NIS2 (Network and Information Systems) Directive , adopted by the European Union, imposes a strict framework for strengthening cybersecurity in 18 strategic sectors. The aim is to guarantee a high level of protection in the face of growing threats.
This regulation introduces strong obligations and severe penalties for the organisations concerned, in order to :
- Protect critical systems against cyber-attacks.
- Anticipate risks to reduce operational impact.
- Ensure business continuity in a context of persistent threats.
By complying now, you can secure your critical assets and strengthen your organisation's resilience.
What challenges does NIS2 represent for your organisation, and how can you meet them?
The NIS2 Directive transforms cybersecurity into a strategic obligation for organisations operating in key sectors. From 2026, compliance will be verifiable and enforceable, and managers will be legally liable in the event of serious breaches.
Companies must now demonstrate active governance, implement minimum technical measures, manage their critical suppliers, and promptly report any major incident.
Here are the key needs to address to avoid the risk of non-compliance:
- Identify your regulatory status
Determine whether you are an essential or important entity via the website of the competent authority in your country that oversees the application of the NIS2 Directive (e.g. ANSSI in France, CCB in Belgium, BSI in Germany, NCSC-NL in the Netherlands, ACN in Italy or MSB in Sweden) to find out your obligations and avoid unintentional non-compliance. - Involve management and structure governance
NIS2 requires the direct involvement of senior management. You need to define roles, document decisions and prove that management is really in charge of cybersecurity. - Carry out a documented risk analysis
Understand your vulnerabilities and critical dependencies, and prioritise your actions to reduce risk. - Implement detection and response mechanisms
Develop alert processes, crisis plans and rapid incident notification to ensure an effective response. - Control your critical suppliers
Identify your strategic suppliers, assess their level of security and demonstrate that you control your external dependencies.
The 4 pillars of the NIS2 Directive
The NIS2 Directive imposes stringent requirements to reinforce cybersecurity in critical organisations. It is based on four fundamental pillars: Governance, Protection, Defense and Resilience. These principles translate into concrete obligations for companies, whatever their sector.
Compliance with the NIS2 Directive is not limited to technical measures. It directly engages management and transforms cybersecurity into a strategic issue. Top management must steer the strategy, approve the security policy and allocate the necessary budgets to guarantee the protection of critical systems.
This involvement is not optional: in the event of a serious breach, responsibility is personal. This means that management must demonstrate active governance, document its decisions and establish a genuine cyber culture at decision-making level.
The aim is to make cybersecurity a strategic priority, and not just an IT (Information Technology) issue.
The NIS2 Directive requires robust preventive measures to be put in place to protect critical infrastructures. These include strict access controls, effective network segmentation and encryption of sensitive data.
But protection doesn't stop there: it requires continuous monitoring and proactive vulnerability management to anticipate threats before they become critical.
The aim: to reduce the attack surface and limit risks, so as to guarantee the availability of essential services.
Faced with increasingly sophisticated cyber-attacks, the NIS2 Directive requires immediate reaction capability. Organisations must put in place systems such as SOCs (Security Operations Centers), SIEM (Security Information and Event Management) solutions and effective alert procedures.
In the event of a major incident, you must notify the competent authority in your country within 24 hours. This requirement is designed to limit the impact of attacks and prevent them from spreading.
Objective: to move from a reactive to a proactive posture to protect critical assets.
Cybersecurity is not just about prevention: it's also about ensuring business continuity, even in the event of a crisis. Organisations need to draw up continuity and disaster recovery plans, regularly test their effectiveness, and secure their supply chains.
This approach helps maintain the confidence of customers, partners and authorities, while ensuring the availability of essential services.
The aim is to build resilience to cope with crises without major disruption.
Case studies by sector: how NIS2 applies to your environment?
The NIS2 Directive imposes strong obligations that vary according to the operating context. Here are some concrete examples to help you understand the challenges and actions required in different sectors.
A territorial hospital group manages several interconnected hospitals, with critical information systems and an increase in cyber-attacks targeting healthcare. The constraints are numerous: 24/7 services, heterogeneous infrastructures, limited resources and heavy reliance on external service providers.
Against this backdrop, the NIS2 Directive requires enhanced cybersecurity governance. Management must be involved in strategy, approve security policies and demonstrate its active role. Incident management has become crucial: any major attack must be detected and reported to the relevant national authority within 24 hours.
Finally, the mapping of critical providers and proof of compliance during audits are essential to avoid sanctions and guarantee continuity of care.
In the industrial sector, a company operates critical infrastructures with an aging OT (Operational Technologies)/IT installed base. The constraints are severe: continuous production, the impossibility of shutting down certain machines, technical obsolescence and dependence on the supply chain.
To comply with NIS2, the company must carry out a documented risk analysis, identify its vulnerabilities and prioritise actions without blocking production. Network segmentation and reliable backups are essential to limit risks.
This approach secures systems while maintaining industrial performance, an essential balance to avoid costly interruptions and regulatory sanctions.
An IT supplier hosts sensitive data and operates shared infrastructures for several customers. Constraints include multi-client environments, strict SLAs (Service Level Agreements) and shared responsibility.
The NIS2 Directive requires demonstrable cybersecurity governance and robust incident detection mechanisms. The service provider must reinforce the security of access, logs and shared environments.
Beyond compliance, this posture is a commercial lever: it reassures customers, reduces contractual risks and constitutes a competitive advantage in calls for tender.
A metropolis manages critical public services such as transport, waste management, drinking water and citizen relations. The constraints are manifold: limited budgets, heterogeneous systems and dependence on public procurement contracts.
To meet NIS2 requirements, the local authority needs to structure a cross-functional cybersecurity management structure, make its business continuity and recovery plans more reliable, and train its management in crisis management.
The objective is clear: prevent a cyber attack from interrupting an essential public service, which would have major consequences for the population and the community's reputation.
A logistics company depends on a complex network of suppliers, warehouses and digital solutions to support its operations. Constraints include just-in-time flows, heavy dependence on partners, and regulatory and reputational pressure.
The NIS2 Directive requires supply chain risks to be assessed and critical partners to be secured. The company must demonstrate the reliability of its operations to reassure its customers and avoid any major disruption.
This approach is strategic: it protects business continuity and reinforces confidence in a sector where speed and reliability are competitive assets.
