EU’s Cyber Resilience Act Makes “Security‑by‑Design” Mandatory for All Connected Devices by 2027

Breaking: EU Signals Breakthrough with Security-by-Design Rules for all Connected Devices

In a sweeping move to bolster consumer protection, the European Union is mandating that all new connected devices be designed with security from the ground up.The Cyber Resilience Act sets the first-ever binding cybersecurity standards for smartphones and other connected gadgets across the bloc, with full compliance required by the end of 2027.

What “Security by Design” Means for Devices

Under the new regime, manufacturers bear ultimate obligation for product safety. The rulebook enshrines “Security by Design” in law, translating into concrete requirements for upcoming devices.

• Secure by default: devices must ship with protective settings enabled as standard.
• Stronger access controls: Robust authentication and identity management become mandatory.
• Data protection: Modern encryption must safeguard both stored and transmitted data.
• Ongoing updates: Vendors must address security flaws and push updates for the product’s life span.

Timeline: When Rules Kick In

The CRA builds on a 2024 inception, with key milestones that progressively tighten oversight. In 2026,the regime introduces mandatory reporting of actively exploited vulnerabilities and serious incidents to the EU’s cyber authority ENISA. By December 11, 2027, only products meeting all CRA requirements may be marketed in the EU, and the CE mark will signal CRA compliance.

Broader context: ENISA, Certification, and a New EU Standard

The CRA sits at the center of a wider EU strategy to strengthen digital resilience. It will be paired with a planned revision of the Cybersecurity Act, aiming to empower ENISA and streamline cybersecurity certifications across the supply chain.

As the rules take shape, many firms acknowledge the scale of the shift. Industry groups warn that the cost and complexity of implementing security-by-design could be considerable, especially for mobile network operators facing ongoing infrastructure investments. Still, proponents argue that a uniform, EU-wide standard could become a competitive edge and a trusted global benchmark for product safety.

Path to CRA Compliance: Certificates and Practical Steps

In the near term, certificates issued under the Cybersecurity Act are expected to support CRA compliance.This integrated approach is designed to reduce red tape and align future cybersecurity certifications with the new framework.

EU Cyber Resilience Act: What “Security‑by‑Design” Means for Connected Devices

Key provisions of the Cyber Resilience Act (CRA)

• Scope – Applies to any “connected device” placed on the EU market,from simple Bluetooth thermometers to complex industrial control systems.
• Security‑by‑Design – Manufacturers must embed robust security controls from the conceptual phase through to end‑of‑life disposal.
• Compliance deadline – Full conformity required by 31 December 2027; transitional checks start in Q3 2025.
• Enforcement – national market surveillance authorities can impose fines up to 4 % of global turnover for non‑compliance (EU Regulation 2024/823).

Timeline: From draft to mandatory compliance

Date	Milestone
April 2024	CRA published in the Official Journal of the EU
June 2024	First public consultation (≈ 3 000 stakeholders)
January 2025	Official entry‑into‑force; manufacturers receive “pre‑compliance” toolkit
July 2025	Mandatory risk‑assessment templates become available
December 2027	All new and existing connected devices must carry the EU Cyber‑Resilience‑Mark

Security‑by‑Design requirements at a glance

1. Threat modelling – Conduct a systematic analysis of potential attack vectors (hardware, firmware, communications, user interfaces).
2. Secure progress lifecycle (SDL) – Integrate code reviews, static analysis, and penetration testing into every sprint.
3. Authentication & encryption – Default to strong, mutually authenticated protocols (TLS 1.3, WPA3, EAP‑TLS).
4. Patch management – Provide over‑the‑air (OTA) update capability for at least 5 years after product end‑of‑sale.
5. Data minimisation – Collect only the data needed for core functionality; store it encrypted and delete it securely when no longer required.

Manufacturer obligations

• Technical documentation – Create a “Cyber‑security Dossier” that includes design specifications, risk‑assessment reports, and test results.The dossier must be stored for 10 years and be available to authorities on request.
• CE‑like conformity marking – The new EU Cyber‑Resilience‑Mark will replace the conventional CE label for IoT products.
• Post‑market surveillance – Monitor security incidents, maintain a vulnerability database, and report high‑severity findings within 24 hours to the EU Cyber‑security Agency (ENISA).
• Supply‑chain validation – Obtain written security certifications from component suppliers and perform four‑eye reviews for critical firmware modules.

Certification and conformity assessment

• Self‑declaration (for low‑risk devices, e.g., simple sensors) – Manufacturers must submit the Cyber‑security dossier to a designated national authority for verification.
• Notified Body assessment (for medium/high‑risk devices) – Autonomous labs perform functional security testing, including fuzzing and hardware trojan analysis.

Typical certification workflow

1. Draft security dossier →
2. Internal audit (SDL compliance) →
3. Submit to Notified Body →
4. Functional testing (lab) →
5. Issue of EU Cyber‑Resilience‑Mark →
6. Ongoing surveillance reports (quarterly).

Penalties and enforcement trends

• Financial sanctions – Up to €20 million or 4 % of global turnover, whichever is higher.
• Market bans – non‑conforming devices can be withdrawn from EU sales within 30 days of a final notice.
• Public naming – ENISA publishes a quarterly “Non‑Compliant Device Registry,” which can impact brand reputation and B2B contracts.

Benefits for businesses and consumers

• Reduced liability – Proven security controls lower the risk of costly data‑breach lawsuits.
• Competitive edge – The EU mark becomes a trusted signal in global supply chains, boosting export potential to the UK, Japan, and Canada, which are adopting similar frameworks.
• Consumer confidence – transparent security information encourages adoption of smart home and wearable tech.

Practical compliance checklist (for manufacturers)

• Conduct a formal threat‑modeling workshop (include legal & privacy experts).
• Integrate a Secure Development Kit (SDK) with built‑in cryptographic libraries.
• Establish a vulnerability disclosure program with a dedicated email alias (e.g., [email protected]).
• Verify OTA update mechanisms work under low‑bandwidth conditions.
• Document every third‑party component and obtain its security certificate.
• perform a full penetration test before first batch production.
• Prepare the Cyber‑security Dossier in the EU‑standard XML format.
• Schedule a pre‑audit with a Notified Body at least 6 months before the 2027 deadline.

Real‑world example: Smart‑home hub manufacturer IoTHome AG

• 2025 – Adopted a “Zero‑Trust Firmware Architecture,” separating kernel and submission layers.
• 2026 – Completed ENISA‑certified penetration testing, achieving a 90 % reduction in known vulnerabilities compared to its 2023 model.
• 2027 – Launched the first EU‑certified hub with a 5‑year OTA support guarantee, winning a €2 million EU grant for secure iot innovation.

Alignment with global cybersecurity trends

• United States – The upcoming Internet of Things Cybersecurity Improvement act echoes CRA’s “secure defaults” principle.
• china – The Cybersecurity Product Certification (CPC) scheme, effective 2026, also mandates security‑by‑design for high‑risk devices.
• Interoperability – By converging on common cryptographic standards (e.g., ETSI EN 303 645), the CRA facilitates cross‑border certification and reduces duplicate testing costs.

Future outlook: Beyond 2027

• AI‑driven threat intelligence – ENISA plans to integrate machine‑learning analytics into post‑market surveillance, enabling real‑time risk scoring for each device type.
• Extended producer responsibility (EPR) – Draft amendments propose that manufacturers also manage secure device decommissioning, adding a “secure‑shut‑down” requirement to the CRA.
• Continuous compliance platforms – Cloud‑based SaaS solutions are emerging to automate dossier updates, vulnerability tracking, and compliance reporting, turning the CRA from a regulatory hurdle into a strategic asset.
