EU Cyber Resilience Act Compliance Guide: Getting Ready for SBOM and Vulnerability Reporting

The EU Cyber Resilience Act begins vulnerability reporting obligations in September 2026 and applies in full from December 2027. Here are the three steps to take now, from automated SBOM generation to 24-hour reporting and supplier contract clauses.

If Your Software Ships to Europe, This Applies to You

The EU Cyber Resilience Act (CRA) entered into force in December 2024. The transition period sounds generous, but the milestones arrive quickly.

  • 11 September 2026: Reporting obligations begin for actively exploited vulnerabilities and severe incidents
  • 11 December 2027: Full application
  • Penalties: Up to €15 million or 2.5% of global annual turnover, whichever is higher
  • The regulation covers manufacturers, importers, and distributors placing "products with digital elements" on the EU market. This is not limited to packaged software. Embedded devices with firmware, industrial control software, and cloud-connected IoT products all fall within scope. HMI software on equipment that a Korean manufacturer ships to a European buyer is no exception.

    What Level of Detail an SBOM Requires

    Annex I of the CRA requires manufacturers to identify and document product components and to produce an SBOM in a commonly used machine-readable format covering at least top-level dependencies. In practice, you need:

  • Component name, version, supplier, and hash for integrity verification
  • License information and dependency relationships
  • A retention scheme that lets you produce records on request from market surveillance authorities
  • The critical point is that this must exist before you are asked for it. Reconstructing the composition of a past release after an authority comes knocking is effectively impossible. Standardize on either SPDX or CycloneDX, wire a tool such as Syft or cdxgen into your CI/CD pipeline, and generate the SBOM on every build. Store the SBOM under the same version tag as the release artifact so the two remain traceable together.

    The Operational Weight of Vulnerability Reporting

    The deadlines that take effect in September 2026 are tight.

  • Within 24 hours: Early warning notification
  • Within 72 hours: Vulnerability notification with corrective measures
  • Within 14 days (vulnerabilities) / one month (severe incidents): Final report
  • Reports go to the coordinating CSIRT and ENISA through a single reporting platform. Factoring in the European Vulnerability Database (EUVD) operated by ENISA adds another touchpoint. Meeting a 24-hour deadline is not a technical problem but an organizational one. Unless you document who judges whether exploitation is active, who signs and submits the report, and who covers when that person is unavailable, the clock will run out.

    Why an SBOM Alone Does Not Reduce Supply Chain Attacks

    Having an inventory does not by itself improve security. Programs commonly stall in these states:

  • SBOMs accumulate, but there is no SLA from vulnerability discovery to patch
  • Identifying affected products and customers after a new CVE drops takes days
  • Supplier and outsourcing contracts never required SBOM delivery for the code they hand over
  • The test is simple. If a CVE with a severity score in the nines were published today, could you list the affected products within minutes? If the answer is days rather than minutes, your SBOMs are a pile of files, not an asset.

    Three Steps to Start Now

    Step 1 — Product inventory and scope assessment: List every product and module, determine EU market exposure, classify each product (default, important, critical), and establish the basis for the minimum five-year support period.

    Step 2 — Automate SBOM generation: Add SBOM generation, signing, and retention stages to your CI/CD pipeline, and store the output alongside each release artifact.

    Step 3 — Formalize procedures and contracts: Document vulnerability monitoring, patch SLAs, named reporting owners and backups, and supplier SBOM delivery clauses.

    The POLYGLOTSOFT Approach

    POLYGLOTSOFT recommends integrating SBOM generation and verification into your existing build pipeline rather than rebuilding it from scratch. We design compliance frameworks that extend to deliverables from outsourcing partners and suppliers, and our subscription development and maintenance services keep you aligned with the September 2026 and December 2027 deadlines on an ongoing basis. If you are unsure how far your compliance scope should reach, start with a product inventory review and reach out to us.
