CRA Basics: a practical introduction to the EU Cyber Resilience Act

CRA Basics is a starting point for understanding the EU Cyber Resilience Act (CRA) and what it means for products with digital elements. CRA aims to raise the cybersecurity baseline across the EU by requiring security by design and by default, clearer accountability, and consistent vulnerability handling throughout the product lifecycle.

This page gathers introductory guidance and related posts to help teams quickly understand the fundamentals, identify what is likely in scope, and plan a realistic path toward implementation and ongoing compliance.

What is the CRA in simple terms

The CRA is an EU regulatory framework focused on improving cybersecurity outcomes for products with digital elements placed on the EU market. It encourages organizations to build secure products, ship safer default configurations, and maintain security through updates and vulnerability management over time.

Why CRA Basics matters for product teams

Even a high-level understanding of CRA helps product, engineering, security, and operations teams align early on scope, ownership, documentation needs, and lifecycle responsibilities. Getting the basics right reduces late-stage rework and helps prevent compliance efforts from turning into reactive fire drills.

Key concepts in CRA Basics

These concepts appear repeatedly when translating CRA into engineering and operational practices.

Products with digital elements

CRA is centered on products that include software or digital connectivity. This can include software applications, embedded software, connected devices, and other digital components that may introduce cybersecurity risk.

Security by design

Security by design means planning and implementing cybersecurity controls from the earliest stages of product development, rather than adding them later. It typically includes threat modeling, secure architecture decisions, and preventive engineering controls.

Security by default

Security by default means products should be delivered with secure settings out of the box. Risky defaults such as weak credentials or unnecessary exposed services should be avoided unless there is a controlled and justified need.

Vulnerability handling over the lifecycle

CRA places emphasis on having a structured process to receive vulnerability reports, assess severity and impact, deliver fixes, and communicate updates. Maintaining products through security updates is central to CRA outcomes.

CRA Basics: what to do first

A lightweight starting plan helps you move from awareness to action without creating unnecessary overhead.

Step 1: identify likely scope

• Create a simple inventory of products and versions shipped to the EU market
• Document key components and critical dependencies
• Note major customer deployment models and default configurations

Step 2: assign ownership and roles

• Name a single internal owner for CRA coordination
• Define responsibilities across product, engineering, security, legal, and support
• Establish escalation paths for high-severity vulnerabilities

Step 3: establish foundational controls

• Adopt secure coding and review practices
• Integrate security testing into CI/CD (static, dependency, and where relevant dynamic testing)
• Define a vulnerability intake and triage process with internal SLAs
• Set a security update and supported-version policy

Step 4: start collecting baseline evidence

• Architecture overview and trust boundaries
• Threat model and risk assessment notes
• Security test outputs and remediation tracking
• Documented vulnerability management workflow and communications approach
