The NIS2 Directive, which aims to establish a high common level of cybersecurity across the EU, is being transposed at varying speeds and approaches by EU member states.
Thus far, 15 of the 27 EU countries have adopted national legislation to implement NIS2.

Cullen International’s assessment of 18 member states also reveals differences in how key aspects of the directive are being transposed. For example, some countries (e.g. the Czech Republic and Spain) could expand the scope of sectors covered by NIS2.
In nine of the surveyed countries, the telecoms sector remains under the supervision of the national regulatory authority (NRA).
Additionally, the research identifies national authorities responsible for oversight, cybersecurity incident response, and coordination within the digital sectors.
