EU Cyber Resilience Act — Guide for Chief Technology Officer (CTO)

Under the EU Cyber Resilience Act, the CTO is the senior technical officer accountable for ensuring products with digital elements comply with Annex I essential requirements before they reach the EU market. This is not merely a delegated task — the CTO's signature on the Declaration of Conformity carries legal weight. If a product is found non-compliant after market entry, regulators can trace technical decisions back to the CTO. The CRA creates a durable obligation: compliance is not a one-time gate at launch but a continuous obligation throughout the support period. CTOs must build internal capability to sustain this, not rely on a point-in-time audit.

On a practical level, CTOs must ensure their engineering organisation delivers on three core CRA obligations continuously. First, SBOM production and maintenance: every product release must be accompanied by a machine-readable software bill of materials, and the process must be automated into the CI/CD pipeline. Second, vulnerability management: when CVEs are identified in components on your SBOM, teams must assess, patch, and release updates within a timeframe that meets Article 14 obligations. Third, update infrastructure: products must support a mechanism for security updates — whether over-the-air, manual, or via a managed channel — and that infrastructure must be resilient. CTOs who treat these as one-off projects rather than engineering capabilities will find compliance unsustainable.

CRA compliance is cross-functional. The CTO must work closely with the CISO to ensure security testing programmes meet Annex I requirements and that the PSIRT has the tools and authority to respond to vulnerabilities. Legal Counsel needs technical input to draft accurate DoC language and to understand which products fall under which conformity assessment route. The Compliance Officer needs technical documentation from engineering teams to populate Annex IV technical files. Product Managers need CRA requirements translated into roadmap items with clear engineering costs. Establish a standing CRA steering group with CISO, Legal, and Product that meets at least monthly and escalates blockers to you.

The most common CTO mistake is scoping CRA compliance too narrowly — assuming it only applies to your flagship connected product while overlooking SDKs, libraries, or component products supplied to integrators. Under the CRA, any product with digital elements placed on the EU market must comply, including B2B components. A second trap is treating the SBOM as a legal document rather than a living engineering artefact: SBOMs that are not integrated into your vulnerability management workflow are worthless for Article 14 purposes. Third, many CTOs underestimate the support period obligation — the CRA requires security updates for the expected product lifetime or at least five years, meaning EOL decisions now carry regulatory consequences.

Use this checklist to establish your CRA foundation:

1. Inventory all products with digital elements placed or intended for the EU market — include SDKs and B2B components
2. Classify each product against the CRA risk categories (default, important Class I, important Class II) to determine conformity assessment route
3. Commission an SBOM gap assessment — can your teams produce a compliant SBOM for every product today?
4. Audit your update infrastructure — does every product support security updates for its full support period?
5. Assign a CRA programme lead with cross-functional authority and a direct reporting line to you
6. Schedule DoC review with Legal Counsel for your highest-risk products first
