The evolution from NIS to NIS2 brought about significant modifications to address modern cyber challenges. The three primary differences are:
Expansion of Scope: NIS2.0 has broadened its purview to include a variety of new economic sectors. This ensures that a greater number of organizations, integral to contemporary digital ecosystems, are now under its ambit.
Enhanced Consistency: NIS2 rectifies implementation ambiguities present in NIS. It offers explicit guidance on security protocols, incident reporting, and enforcement measures, fostering uniform implementation across organizations and EU member states.
Collaborative Crisis Management: One of NIS2's standout features is its robust emphasis on strategic planning and collaboration. It facilitates coordinated crisis management and emphasizes increased cooperation among member states during large-scale cybersecurity incidents.
Furthermore, while NIS2 upholds the foundational tenets of the NIS1 Directive, it incorporates these enhancements in response to identified gaps like varied cyber resilience levels among EU entities and a fragmented understanding of cyber threats.
