NIS2: What Companies Need to Know About the New Cybersecurity Directive

NIS2: What Companies Need to Know About the New Cybersecurity Directive 

In recent years, digital transformation has accelerated at an unprecedented pace. While this technological progress offers many benefits, it also brings significant risks. Cyber threats are becoming increasingly sophisticated, prompting the European Union to introduce the Network and Information Security Directive 2, better known as NIS2. Adopted in October 2022, this directive replaces the original NIS Directive and aims to enhance the digital resilience of essential and important sectors within the EU. 

What is NIS2? 

NIS2 is a comprehensive revision of the original NIS Directive introduced in 2016. The original NIS Directive was the first EU-level legislation focused on improving the cybersecurity of vital infrastructures like energy, transport, and finance. However, NIS2 significantly expands these obligations and imposes stricter requirements on a broader range of organizations and sectors. 

NIS2 covers companies considered "essential," such as those in energy and water management, and also extends to healthcare, food supply, and digital infrastructure sectors. Additionally, providers of digital services such as cloud providers and online marketplaces are now explicitly included under the directive. 

Key Updates and Guidelines  

One of the most significant changes introduced by NIS2 is the requirement for companies to implement stricter security measures, which include:  

1. Security Policies and Risk Management: Organizations must develop a thorough cybersecurity policy that identifies and manages risks. This policy must be regularly evaluated and updated to address emerging threats. 
2. Incident Management: Companies must be able to respond quickly and effectively to cybersecurity incidents. This includes reporting incidents to relevant authorities within 24 hours and restoring systems to support operational continuity. 
3. Supply Chain Management: With a reliance on critical third-party services, companies must closely monitor and manage the cybersecurity of their suppliers and partners. 

This directive not only imposes new obligations but also strengthens enforcement mechanisms. National supervisory authorities now have more power to audit companies and impose penalties for non-compliance. Fines can reach up to €10 million or 2% of global annual turnover, whichever is greater. 

Implications for Companies 

NIS2 mandates a thorough review of companies’ current cybersecurity practices. This necessitates  investments in technology, processes, and personnel to meet the new requirements. It is also essential that companies foster a culture of cybersecurity awareness, where everyone within the organization understands the risks and responsibilities. 

For smaller companies, complying with NIS2 may be challenging due to the complexity and costs associated with implementing advanced security measures. The directive recognizes these challenges and offers some flexibility for smaller entities, though the fundamental obligations remain in place. 

Conclusion 

NIS2 marks a significant step forward in the European approach to cybersecurity. By enforcing stricter regulations and widening its scope, this directive helps strengthen the digital resilience of essential and important sectors and encourages companies to proactively secure their systems and data. Acting promptly and implementing the right measures ensure compliance with the legislation while also protecting business continuity and reputation in a challenging digital landscape.
