One Team Risk Management Solution

What is the CER Directive?

The Critical Entities Resilience Directive (EU 2022/2557) establishes a common European framework for strengthening the resilience of organisations that provide essential services. The Directive applies across eleven critical sectors including energy, transport, health, digital infrastructure, water, public administration, banking, financial market infrastructure, food and space.

The objective is to ensure that critical services remain available during major disruptions arising from natural hazards, severe weather, operational failures, supply chain disruption, infrastructure incidents and malicious acts.

Irish Legislative Framework

In Ireland, the Directive has been implemented through the European Union (Resilience of Critical Entities) Regulations 2024 (S.I. No. 559 of 2024), which came into effect on 17 October 2024.

Competent Authorities are responsible for identifying and supervising Critical Entities within their sectors. Designated organisations must comply with specific resilience obligations and be capable of demonstrating that resilience is actively managed and continuously improved.
