Introduction

The Cyber Resilience Act (CRA) represents a fundamental shift in the technology policy, moving cybersecurity from a voluntary best practice into a strict legal gatekeeper for the European market. It stipulates that products within the CRA scope must comply with the relevant CRA obligations before being allowed entry into the EU market.

For embedded developers, product managers, and decision makers, the message is clear: CRA readiness should begin now. The regulation introduces obligations across the full product lifecycle, including secure design, vulnerability handling, security updates, incident reporting, technical documentation, and conformity assessment. This guide translates the CRA’s requirements into practical engineering and planning considerations. Each chapter explains a key compliance topic and concludes with an action checklist to assist teams in identifying gaps and starting to address them promptly.
