Impact of NIS2 Directive on Business Compliance

This document is a technical report discussing the new Network and Information Systems Directive 2022/2555 (NIS2) which is part of the EU's digital and cyber security strategy. The directive, effective from 18 October 2024, replaces the previous NIS Directive 2016/1148 and expands its regulatory scope to include more industries, particularly those deemed critical to the economy and society. It outlines the obligations for businesses classified as essential or important entities, including the need for robust cybersecurity risk-management measures, governance responsibilities, and incident reporting protocols. The report details the sectors affected by NIS2, including healthcare, energy, and digital services, and explains the penalties for non-compliance. It also discusses the relationship between NIS2 and existing standards like ISO 27001, emphasizing that while NIS2 is mandatory, ISO 27001 can assist in meeting its requirements. Additionally, the report notes the ongoing transposition process in EU Member States and the UK's approach to cybersecurity regulation post-Brexit.
