CRA Annex I Essential Cybersecurity Requirements

Translate the Cyber Resilience Act's product-security and vulnerability-handling requirements into controls that engineering, product, and compliance teams can evidence.

Use this page to separate risk-based product properties from lifecycle duties, then connect both to technical documentation and release evidence.

Overview

Annex I is the control backbone of the Cyber Resilience Act. Part I defines the cybersecurity properties that an in-scope product with digital elements must have where applicable on the basis of the cybersecurity risk assessment. Part II defines the manufacturer's vulnerability-handling processes, which apply when the product is placed on the market and throughout the support period.

Section 1

What Article 6 makes Annex I do

Article 6 ties market access to Annex I. A product with digital elements may be made available on the market only if the product meets the applicable Part I requirements and the manufacturer's processes comply with Part II.

That means Annex I should be treated as a conformity argument, not as a generic security wishlist. The useful working file is a requirement register that shows the requirement, the product boundary, the risk assessment outcome, the implemented control, the test or review evidence, and the documentation location.

  • Start with the product as placed on the market, including software versions, intended purpose, reasonably foreseeable use, and relevant remote or integrated components.
  • Use the cybersecurity risk assessment to decide which Part I point (2) requirements apply and how they are implemented.
  • Keep Part II separate as the operating model for vulnerability identification, remediation, testing, disclosure, reporting contact, and secure updates.
  • Where a Part I requirement is not applicable, record the specific product reason and the related risk treatment in the technical documentation.
Section 2

Annex I Part I: product-security outcomes

Part I starts with an overall requirement for an appropriate level of cybersecurity based on the risks, then lists product properties that apply where relevant. The Commission FAQ explains that manufacturers must determine relevance through the cybersecurity risk assessment, and that non-applicability needs a clear justification.

A practical Annex I Part I assessment should therefore avoid yes-or-no labels without evidence. Each answer should point to design choices and tests that show how the product meets the relevant outcome.

  • Known exploitable vulnerabilities: show the vulnerability status and release gate used when the product is placed on the market.
  • Secure by default: document default accounts, exposed services, cryptographic defaults, certificate validation, reset behaviour, and any tailor-made business-user deviation.
  • Security updates: explain how vulnerabilities can be addressed, when automatic security updates are applicable, and how users can opt out or postpone where the CRA requires that choice.
  • Protection controls: map requirements for access control, confidentiality, integrity, data minimisation, availability, attack-surface reduction, exploitation mitigation, logging, and secure removal or transfer of data and settings.

Section 3

Annex I Part II: vulnerability handling during the support period

Part II is not limited to launch readiness. It sets the manufacturer's vulnerability-handling process for the product, including integrated components, throughout the support period.

The CRA does not require the same patch response for every vulnerability, but it does require the manufacturer to assess relevance and risk, then put appropriate remedies in place without delay. A remedy may be a patch, mitigation, configuration guidance, advisory, documentation change, or another suitable measure, depending on the risk.

  • Maintain a vulnerability and component record, including an SBOM in a commonly used, machine-readable format covering at least top-level dependencies.
  • Process internal findings, external reports, component vulnerabilities, and third-party information through one triage and remediation workflow.
  • Run effective and regular security tests and reviews, and update the cybersecurity risk assessment where those activities reveal relevant information.
  • Publish information about fixed vulnerabilities once an update is available, including affected products, impact, severity, and clear remediation information, unless a justified short delay is needed so users can apply the fix.
  • Maintain a coordinated vulnerability disclosure policy, a reporting contact, secure update-distribution mechanisms, and free security updates unless the CRA's tailor-made business-user exception applies.
Section 4

Secure-by-design work products to keep

The CRA covers planning, design, development, production, delivery, and maintenance. For Annex I, secure-by-design work is strongest when it produces records that are usable at release review and later by a notified body or market surveillance authority.

The goal is not to publish every internal engineering record. It is to maintain enough traceability to show how the product and the manufacturer's processes meet the applicable Annex I requirements.

  • Product boundary file: product model or version, software affecting compliance, intended purpose, foreseeable use, remote data processing, integrated components, and user-facing security assumptions.
  • Risk and requirement matrix: Annex I point, applicability decision, reason, control design, test method, evidence link, owner, and residual issue handling.
  • Release gate evidence: vulnerability search results, open vulnerability disposition, default-configuration checks, update-channel checks, and user-information review.
  • Lifecycle evidence: vulnerability intake records, triage decisions, remediation plans, security update records, advisory publication records, CVD policy location, and support-period rationale.
Section 5

Technical documentation and authority evidence

Article 31 requires technical documentation to contain the data or details used to show that the product and the manufacturer's processes comply with Annex I. Annex VII then specifies the minimum documentation elements, including the cybersecurity risk assessment, vulnerability-handling process information, test reports, standards or alternative solutions, support-period information, and where applicable the SBOM.

The Commission FAQ emphasises that technical documentation may be requested by market surveillance authorities and should be comprehensive and clear. It also explains that the risk assessment and documentation should be updated where relevant information emerges after placement on the market.

  • Keep the cybersecurity risk assessment in the technical documentation and link it to the Annex I Part I applicability record.
  • Describe vulnerability-handling processes, including the SBOM, CVD policy, reporting contact, and secure update-distribution solution.
  • List harmonised standards, common specifications, certification schemes, or other technical specifications used; where they are not used, describe the alternative solution adopted.
  • Keep test reports, review outputs, EU declaration of conformity records, user-information evidence, and support-period rationale aligned to the product version placed on the market.
  • Treat unsupported assertions such as 'low risk' or 'not applicable' as incomplete unless the file shows the product-specific basis and the control or mitigation chosen.
