Clarity on the EU Cyber Policy Mosaic

Comparing major EU cybersecurity and resilience policies aids in
evaluating consequences of noncompliance. Adhering to the General Data Protection Regulation (GDPR), Critical Entities Resilience Directive (CER-D), Network and Information Systems version 2 Directive (NIS2D), Digital Operational Resilience Act (DORA), and Cyber Resilience Act (CRA) can limit business impact by strengthening organizational security
habits.

This guide covers cross-domain security, including IT, operational
technology (OT), and product security programs. It highlights compliance overlaps between policy focus areas, isolates unique requirements, and references international standards that help
organizations prepare for and comply with a variety of EU cyber policies. This guide documents the scope and purpose of each policy, critical questions for implementation, and current general implementation status across EU states. While every case is unique, this paper simplifies the EU policy landscape and provides a helpful starting place for evaluating compliance posture.
