In a nutshell: From May 2026, NIS2 requirements will be actively enforced by EU authorities, the implementation deadline expires and enforcement measures take effect.
May 2026 marks the end of the transition period for the NIS2 Directive; EU member states now begin enforcement against operators of critical infrastructure and important service providers. This marks the transition from the implementation phase to binding controls and sanctions.
The Network and Information Security Directive 2 (NIS2) is entering its operational phase. Since organisations were able to build up their security measures following implementation in 2024, the period of compliance verification and enforcement by national regulatory authorities now begins.
For CISOs, this concretely means: Previously recommended security measures become binding requirements whose compliance must be documented and proven. Authority inspections, audits and enforcement protocols come into force. Organisations must bring their incident response plans, network segmentation, multi-factor authentication and supply chain risks up to the standard required by the directive.
Enforcement is carried out by national authorities such as the Bundesnetzagentur (Germany), FICORA (Finland) or equivalent bodies in other EU countries. Violations can result in substantial fines and operational prohibitions. Organisations should immediately evaluate their compliance positions and close any gaps.
