Make ISO 27001 your gas pedal to NIS 2

In this article, we explore how to useISO 27001 as a lever for compliance with the NIS 2 directive.

What is NIS 2?

La directive NIS 2 (Network and Information Security) est une régulation européenne renforçant les exigences de cybersécurité pour les entités essentielles et importantes au sein de l’Union européenne. Elle élargit et renforce la précédente directive NIS1, en imposant 20 objectifs de sécurité déclinés en exigences opérationnelles, avec deux niveaux d’application :

It requires the implementation of 20 safety objectives, broken down into operational requirements, with two levels of application:

• Standard obligations for large entities
• More stringent obligations for essential entities

NIS 2 also applies to theecosystem of suppliers: providers with an impact on security must also be compliant.

A guideline that's still unclear but has a structuring effect

Bien que juridiquement contraignante, NIS 2 reste rédigée de manière assez générale, ce qui peut conduire à deux risques majeurs :

• Oversizing certain measures
• Omissions on critical points

Bien appliquée, la directive NIS 2 constitue au contraire un avantage concurrentiel majeur. En structurant leur cybersécurité, les entreprises améliorent leur résilience, leur crédibilité et leur attractivité auprès des partenaires et clients.

Anticipate NIS 2, or endure its implementation?

Face à l’entrée en vigueur prochaine, faut-il attendre un contrôle ou agir dès maintenant ?

Fort de plus de 150 projets de certification ISO 27001 accompagnés, nous constatons que la plus grande erreur est de réduire NIS 2 à une simple liste de vérifications réglementaires.

Taking the time to anticipate: a strategic challenge

You have three years to comply with NIS 2. You should use this time to :

• Rapidly deploy risk reduction measures
• Design solutions tailored to your business challenges
• Anticipate the impact on your information system
• Align safety measures with your real risks

NIS 2 requires a continuous risk management approach, not a one-off treatment. It's about managing cybersecurity, not suffering from it.

ISO 27001: a framework for responding to NIS 2

ISO 27001 is today the benchmark standard for cybersecurity certification. It is based on a rigorous method:

• Risk analysis
• Planning measures
• Monitoring and continuous improvement
• Management involvement

It provides a long-term structure for safety.

The contribution of ISO 27001 to the NIS 2 framework

Here are the concrete benefits of an ISO 27001 approach to NIS 2:

1. A rationale based on risk analysis

ISO 27001 makes it possible to prioritize real threats,allocate resources efficiently, and justify the measures put in place - an explicit requirement of NIS 2.

2. Continuous improvement in safety

The standard is based on a PDCA (Plan-Do-Check-Act) cycle, guaranteeing that the safety system is adapted to the organization's evolution.

3. Stakeholder involvement

ISO 27001 promotes cybersecurityacculturation and team mobilization through a common language and clear governance.

4. Strong compatibility between ISO 27001 and NIS 2

NIS 2 requirements and ISO 27001 measures are largely aligned. An ISO 27001-certified organization is already well on the way to NIS 2 compliance.

How to get started on NIS 2 compliance?

Here's a concrete strategy:

1. Perform an ISO 27001 / NIS 2 diagnostic to assess your maturity
2. Perform a risk analysis to target critical actions
3. Structuring cybersecurity governance: roles, indicators, committees
4. Build a realistic, manageable 3-year roadmap
5. Involve management and gradually bring teams on board

ISO 27001 provides the guidelines for structuring, managing and developing your cybersecurity over time.
