We are entering an era of constant digital transformation, where modern societies are increasingly dependent on digital technologies and networks. Related to this are the growing challenges in the area of cyber security. In order to strengthen the protection of European networks and information systems against the threat of cyber-attacks, a new European Directive NIS2 (Network and Information Systems 2) has been created. This initiative brings comprehensive measures and new standards to ensure the resilience of digital infrastructure in the face of increasingly sophisticated threats. This Directive provides companies with a coherent framework and helps them to ensure a sufficient level of cybersecurity.

Basic principles of NIS2
NIS2 builds on the experience of the previous Directive and reflects the dynamic nature of cyber threats. One of the key principles of this directive is the provision of resilient tools for identifying, preventing and then resolving cyber incidents. At the same time, it emphasises cooperation between Member States in order to respond effectively to threats that have no borders.
Scope of NIS2 and changes
The scope of the NIS2 Directive is significantly expanded compared to its previous version, bringing a comprehensive and updated response to the dynamic nature of modern cyber threats into the European legal framework.
The main changes in the scope of NIS2 include:
Extension of scope:
NIS2 redefines and expands the concepts of “digital service providers” and “critical infrastructure operators”. In this way, the Directive covers a wider range of sectors, including health, the financial sector, transport and others. This ensures that key sectors are effectively protected from cyber threats.
Increased responsibility and safety requirements:
The NIS2 emphasises on increasing the accountability of entities considered key to cybersecurity. The new security requirements include regular cyber testing, incident prevention plans and the implementation of security measures. This strengthens the overall resilience of organisations to cyber threats.
Enhanced cooperation between Member States:
NIS2 emphasises the importance of cooperation between companies and countries. The exchange of information and best practices will contribute to a strong network that can respond effectively to the latest cyber threats.
Increased transparency:
NIS2 requires entities to report cyber incidents within 72 hours of detection. This obligation contributes to greater transparency and faster response to incidents, resulting in a reduction of potential impacts on cybersecurity.

Conclusion
It can be said that the NIS2 Directive represents a key step for businesses in the European Union in the area of cyber security, affecting most sectors from energy to healthcare. To comply with this new legal framework, companies should take a proactive approach to identifying the key elements of their infrastructure. The emphasis on regular cyber testing means that companies will need to invest in security audits to identify potential vulnerabilities and risks. Establishing plans for preventing and dealing with cyber incidents is not only the norm, but also a key element for responding quickly and effectively to potential attacks. Implementing specific security measures such as data encryption and software updates is becoming a necessity to strengthen overall cyber resilience. Finally, cooperation with other actors and Member States is becoming a strategic element, with effective exchange of information on cyber threats creating a strong network to protect digital infrastructure within the European Union. Moving from a reactive to a proactive approach is not only an obligation for companies, but also an opportunity to strengthen their cybersecurity in an era of constant and complex cyber threats.
This directive should be seen as a guide for companies to develop and improve their cybersecurity strategies. It offers a structured framework and specific direction that enables companies to better understand modern cyber threats and take appropriate preventative measures. It aims not only to implement regulatory requirements, but also to provide room for innovation and technological development, which can strengthen resilience to cyber threats. By setting clear rules and expectations, NIS2 can act as a guide to help companies build robust and adaptive security practices within an ever-changing cyber environment. It offers companies not only protection from existing threats, but also room for growth and competitiveness.
