Understanding the NIS2 Directive

The Network and Information Security (NIS) Directive was the first comprehensive EU-wide legislation focused on cybersecurity. Its main goal was to establish a high common level of cybersecurity across all Member States, ensuring that essential services and digital infrastructures are robust against cyber threats.

However, implementing the original NIS Directive proved challenging. Member States experienced difficulties that led to inconsistencies and fragmentation in cybersecurity measures across the EU. This inconsistency made it harder to effectively combat the increasing number of cyber-attacks associated with growing digitalization.

To address these challenges and the evolving cyber threat landscape, the European Commission proposed a new directive to replace the original NIS Directive, commonly referred to as NIS2. The objectives of NIS2 are to:

• Strengthen security requirements: Implement more rigorous cybersecurity obligations for organizations, including risk management and incident reporting.
• Address supply chain security: To enhance overall supply chain security, recognize and mitigate risks arising from suppliers and service providers.
• Streamline reporting obligations: Simplify and harmonize the process for reporting cybersecurity incidents to reduce administrative burdens.
• Introduce stringent supervisory measures: Enhance oversight by national authorities to ensure compliance with the directive.
• Implement harmonized sanctions: Establish consistent penalties across Member States for non-compliance to ensure uniform enforcement throughout the EU.

By expanding its scope, NIS2 will oblige a broader range of entities and sectors to adopt cybersecurity measures. This includes more businesses deemed critical to the economy and society, increasing the EU’s overall cybersecurity resilience in the long term.

Legislative Process and Adoption:

• The proposal was assigned to the Committee on Industry, Research and Energy within the European Parliament.
• The committee adopted its report on 28 October 2021.
• The Council of the European Union agreed on its position on 3 December 2021.
• A provisional agreement between the co-legislators (the Parliament and the Council) was reached on 13 May 2022.
• The political agreement was formally adopted by both the Parliament and the Council in November 2022.
• The NIS2 Directive entered into force on 16 January 2023.
• Member States have until 17 October 2024, to transpose the directive’s measures into their national laws.

This means that by October 2024, all EU Member States must implement the provisions of NIS2, leading to a more unified and more robust cybersecurity framework across Europe.

What is the NIS2 Directive?

The Network and Information Security Directive 2 (NIS2) is a comprehensive piece of European Union legislation aimed at enhancing cybersecurity across Member States.

Background of the Original NIS Directive:

The original NIS Directive, adopted in 2016, was the first EU-wide legislation on cybersecurity. It aimed to achieve a high common level of cybersecurity across the Union by:

• Improving National Cybersecurity Capabilities: Encouraging Member States to develop national cybersecurity strategies and establish Computer Security Incident Response Teams (CSIRTs).
• Enhancing Cooperation: Setting up mechanisms for cooperation among Member States.
• Securing Critical Sectors: Requiring Operators of Essential Services (OES) and Digital Service Providers (DSPs) to take appropriate security measures and notify significant incidents to relevant authorities.

Challenges and Limitations of the Original NIS Directive:

Despite its groundbreaking nature, the original NIS Directive faced several challenges:

1. Fragmented Implementation:
   • Divergent National Approaches: Member States had significant leeway in implementation, leading to inconsistencies in cybersecurity measures and enforcement.
   • Variations in Identification of OES: Differences in how the Member States identified operators of essential services resulted in uneven application of the directive.
2. Limited Scope:
   • Sector Coverage: The original directive covered a limited number of sectors, potentially overlooking other critical areas vulnerable to cyber threats.
   • Entity Size: Smaller entities that could still have a significant impact if disrupted were often excluded from obligations.
3. Evolving Cyber Threat Landscape:
   • Increased Digitalization: Rapid digital transformation across industries outpaced the provisions of the original directive.
   • Sophisticated Cyber Attacks: The rise in frequency and complexity of cyber-attacks required more robust and adaptive cybersecurity frameworks.
4. Reporting Obligations:
   • Complexity and Burden: Inconsistent reporting requirements created administrative burdens for organizations operating in multiple Member States.

Reasons for Developing NIS2:

To address these challenges and adapt to the evolving cyber landscape, the European Commission proposed the NIS2 Directive with the following motivations:

• Harmonization: Establish more consistent cybersecurity requirements and supervisory measures across Member States.
• Expansion of Scope: Include additional sectors and entities critical to the economy and society.
• Enhanced Cooperation: Strengthen mechanisms for information sharing and coordinated responses to cross-border cyber incidents.
