CRA Documentation: how to build audit-ready evidence for the EU Cyber Resilience Act

CRA Documentation is the set of technical and organizational artifacts used to demonstrate that a product with digital elements meets the EU Cyber Resilience Act (CRA) expectations. It covers how security is designed, implemented, tested, maintained, and improved throughout the product lifecycle, with a strong emphasis on traceability and repeatability.

This page collects practical guidance and related posts to help teams define a documentation baseline, keep evidence current across releases, and reduce compliance overhead by integrating documentation into existing engineering workflows.

Why CRA Documentation matters

Under CRA, being secure is not sufficient. Organizations should be able to show structured proof of how risks are assessed, how controls are applied, how vulnerabilities are handled, and how updates are delivered over time. Strong documentation reduces ambiguity, accelerates internal reviews, and improves readiness for customer and regulatory scrutiny.

Who owns CRA Documentation

CRA Documentation typically spans multiple teams. Product and engineering own architecture and delivery evidence, security owns control definition and risk governance, and support or operations own vulnerability intake and update processes. A single accountable owner is recommended to keep the evidence set consistent and versioned.

What CRA Documentation typically includes

In most organizations, documentation can be structured into a small number of evidence domains. The exact set depends on your product risk profile, but the goal is consistent: prove that security is systematic and maintained across the lifecycle.

Product security design and risk management

• Security requirements and assumptions
• Architecture overview with trust boundaries
• Threat models and mitigation decisions
• Risk assessments and risk acceptance records

Secure development lifecycle evidence

• Secure coding standards and review practices
• CI/CD security gates and release criteria
• Change management and traceability between requirements and releases
• Access control model for repositories and build systems

Security testing and validation

• SAST/DAST configurations and results summaries
• Dependency scanning and container scanning outputs
• Penetration test reports and remediation tracking
• Verification evidence for critical fixes

Vulnerability handling and post-market activities

• Vulnerability intake and triage workflow
• Internal remediation SLAs and escalation paths
• Coordinated disclosure process and communication templates
• Security update and patch policy, including supported versions

Supply chain and component visibility

• Component inventory and dependency governance
• SBOM where applicable and processes to keep it current
• Third-party risk assessment approach for critical suppliers
• Evidence of response capability for upstream vulnerabilities

How to operationalize CRA Documentation without creating bureaucracy

The most sustainable approach is to treat documentation as a product of normal delivery workflows, not as a separate compliance project. This means embedding documentation outputs into your engineering toolchain and defining lightweight ownership and review cadences.

Documentation principles that reduce long-term effort

• Version everything per release and link artifacts to a specific product version
• Prefer automation for evidence capture (CI logs, scan exports, release checks)
• Use a single evidence index that points to source-of-truth documents
• Define a minimum baseline and expand only where risk justifies it

Recommended structure for a CRA Documentation “evidence pack”

• Overview and scope statement for the product/version
• Architecture and threat model package
• Security testing bundle with summaries and raw outputs
• Vulnerability management policy and operating runbooks
• Support and security update policy (including end-of-life rules)
• Supply chain evidence (inventory, SBOM where applicable, third-party notes)

Metrics to keep CRA Documentation credible

• Remediation time by severity
• Testing coverage across repositories and release pipelines
• Update cadence and supported-version adherence
• Recurring vulnerability classes and preventive actions
