Supervisory measures and cross-border collaboration

Under the NIS2 Directive, the empowerment of National Competent Authorities (NCAs) marks a crucial evolution in the governance of cybersecurity across the European Union. These authorities are vested with comprehensive responsibilities and powers, transforming them into pivotal actors in the enforcement of the Directive's mandates. Their role extends beyond mere oversight; NCAs are now central to guiding entities within their jurisdiction towards robust compliance, ensuring that the principles and requirements of the Directive are not just theoretical ideals but practical realities. This involves a proactive engagement in monitoring the cybersecurity practices of entities, assessing their adherence to the mandated risk management and incident reporting obligations, and providing the necessary support to rectify shortcomings.


The authority granted to NCAs under NIS2 includes conducting detailed audits, a process that enables these bodies to delve into the cybersecurity frameworks of entities, evaluating their effectiveness and identifying areas of vulnerability that need strengthening. In instances where discrepancies or non-compliance are identified, NCAs are empowered to issue directives for remediation, mandating specific actions or improvements to be made within a stipulated time frame. This hands-on approach ensures that compliance is not static but an ongoing process of enhancement and adaptation.


Moreover, the Directive recognizes the criticality of enforcing compliance through tangible consequences for non-adherence. NCAs are equipped with the authority to impose penalties, including substantial fines, for entities found in violation of the Directive's provisions. This enforcement mechanism is designed to serve as a deterrent against complacency and to underscore the seriousness with which the EU regards the cybersecurity of its critical and important infrastructures.


Parallel to the strengthening of supervisory measures is the Directive's emphasis on fostering a collaborative cybersecurity environment that transcends national borders. In the face of cyber threats that are inherently global and indiscriminate, the NIS2 Directive acknowledges the indispensability of cross-border cooperation and information sharing. Instruments like the Cooperation Group and the CSIRTs Network embody this collaborative spirit, facilitating a seamless exchange of intelligence, insights, and best practices among member states.


The Cooperation Group offers a strategic platform where member states, alongside the European Commission and the EU Agency for Cybersecurity (ENISA), converge to deliberate on overarching cybersecurity policies, strategies, and standards. This collective brainstorming and policy-making endeavor is instrumental in harmonizing cybersecurity practices across the EU, ensuring a unified approach to tackling common threats.


On a more operational level, the CSIRTs Network serves as the backbone for real-time cooperation and information exchange on cybersecurity incidents and threats. By enabling national CSIRTs and ENISA to work in concert, the Network enhances the EU's capacity to promptly detect, respond to, and recover from cyber incidents, particularly those with cross-border implications.


This dual focus on robust supervisory measures and cross-border collaboration encapsulated in the NIS2 Directive is pivotal in fortifying the European Union's cybersecurity infrastructure. By enhancing the regulatory authority of NCAs and fostering an environment of cooperative defense, the Directive lays the groundwork for a resilient, unified, and secure digital Europe, poised to counter the complex cyber threats of the modern age.
