This closing article of our CER series summarizes what every critical entity must have in place. ## **Building Resilience: What Every Critical Entity Needs to Know About the CER Directive (Part 10 of our CER Series)**   The **Critical Entities Resilience (CER) Directive** is transforming how critical infrastructure organizations across Europe prepare for, respond to, and recover from threats. Whether you’re operating in energy, transport, water, or digital services, CER demands a shift from isolated risk management to an integrated, all-hazards resilience strategy. Over the past weeks, we’ve published a series of in-depth articles, use cases, and infographics to help critical entities understand and implement the directive. Here is your complete guide:   ---   ### **🔎  1.
