The NIS2 Directive is an updated European Union regulation aimed at strengthening cybersecurity across critical sectors such as energy, healthcare, transport, and digital infrastructure. It requires organizations in these sectors to implement robust security measures, manage cyber risks, and report incidents promptly. Importantly, NIS2 also extends these obligations to key suppliers and service providers, ensuring the entire supply chain is secure. The directive seeks to harmonize cybersecurity standards across EU member states, improve cooperation, and reduce vulnerabilities to cyberattacks, ultimately protecting essential services and citizens.
