What is the NIS2 Directive? – Overview and importance in the EU cybersecurity landscape

Introduction

In today’s digital age, almost every aspect of our daily lives—from communication and transportation to healthcare and finance—depends on secure networks and information systems. However, as we become more interconnected, the risk of cyberattacks has significantly increased. To protect Europe’s critical infrastructure and essential services, the European Union (EU) has established comprehensive cybersecurity regulations. One such regulation is the NIS2 Directive, an update to the original Network and Information Security (NIS) Directive, which was adopted in 2016.

The Network and Information Security (NIS2) Directive is the EU’s legislative framework designed to strengthen the cybersecurity of critical infrastructure and essential services. It aims to protect the systems and networks that underpin vital services like energy, healthcare, transportation, and finance. NIS2 builds upon the original NIS Directive, which was the first EU-wide law on cybersecurity, and it introduces stricter measures to address today’s increasingly complex cyber threats.

Background of NIS1:

The original NIS Directive (also called NIS1) was adopted in 2016. Its main goal was to improve the cybersecurity of essential services like electricity, water, and transportation by requiring Member States to ensure that companies in these sectors took appropriate security measures. NIS1 also aimed to promote cooperation between Member States on cybersecurity issues.

However, since the introduction of NIS1, the cybersecurity landscape has evolved dramatically. The frequency, complexity, and severity of cyberattacks have grown, affecting critical sectors and even entire economies. For example, high-profile cyberattacks like the WannaCry ransomware attack in 2017 disrupted hospital services across Europe, underscoring the vulnerabilities in vital sectors.

Why was NIS2 introduced?

NIS2 was introduced to address the shortcomings of the original NIS Directive. While NIS1 laid the foundation for EU-wide cybersecurity, it became clear that more needed to be done. NIS2 aims to:

   - Improve national cybersecurity capabilities in Member States.

   - Enhance cooperation among EU countries.

   - Expand the range of sectors and services covered.

   - Strengthen the enforcement of cybersecurity measures through stricter penalties.

The directive reflects the EU’s recognition that cybersecurity is not just a technological issue but also a crucial component of modern governance and economic stability.

Why is NIS2 Important?

In an increasingly digitized world, the NIS2 Directive ensures that essential services—such as healthcare, banking, and transportation—are safeguarded from cyber threats. NIS2 extends beyond just preventing cyberattacks; it aims to minimize the impact of incidents on the European economy and society. 

- Expanded Scope: NIS2 covers more sectors than the original directive, recognizing that today’s critical infrastructure is more interconnected and dependent on digital systems.

- Enhanced Cooperation: One of the directive’s key features is improved cooperation between EU Member States. Countries will now be required to share information on cyber threats and incidents, ensuring a coordinated response across the EU.

- Risk Management and Incident Reporting: NIS2 introduces stricter requirements for organizations to manage cybersecurity risks. Companies must implement risk management practices and report any significant incidents within a short timeframe, ensuring that cyber threats are quickly contained and addressed.

The European Commission highlights NIS2 as a core part of the EU’s strategy to achieve a higher level of cybersecurity across all Member States. You can learn more about the directive from the European Commission’s NIS2 page (https://digital-strategy.ec.europa.eu/en/policies/nis2-directive).
