As global cybersecurity threats increasingly target connected hardware and software, regulatory bodies are fundamentally shifting how electronic systems are designed, maintained, and supported throughout their lifecycles. In response to mounting vulnerabilities across the digital ecosystem, the European Union introduced the Cyber Resilience Act (CRA), establishing rigorous, mandatory cybersecurity requirements for all products with digital elements sold within the European market.
For the embedded electronics industry, these new regulations introduce profound challenges. Because embedded systems often feature exceptionally long operational lifecycles and rely on intricate, multi-tiered hardware and software supply chains, manufacturers must rethink their traditional methodologies. They can no longer focus solely on how cybersecurity is addressed during the initial development phase; instead, they must account for how products are placed on the market, how they are maintained, and how they are supported over extended periods.
With core CRA requirements set to enforce full compliance for covered products on December 11, 2027, meeting these standards has become a crucial element of the conformity assessment process associated with CE marking. Products possessing an intended purpose or reasonably foreseeable use that involves a direct or indirect logical or physical data connection to a device or network fall squarely within this regulatory scope. As manufacturers race to align their portfolios with the upcoming deadlines, industry experts warn that three major misconceptions continue to hinder the development of effective CRA compliance strategies.
Misconception 1: "The CRA only applies to devices connected to the internet"
A prevailing myth among hardware developers is that the scope of the Cyber Resilience Act is dictated entirely by whether a given device connects to the public internet. However, the legislation’s reach is far broader and is instead determined by whether a product’s intended purpose or reasonably foreseeable use involves a direct or indirect logical or physical data connection to any device or network.
This critical distinction means that industrial systems, specialized machinery, and commercial devices operating entirely offline or within closed local environments can still be legally required to comply with the CRA. Equipment utilized within local industrial automation networks, closed corporate infrastructures, or systems incorporating specialized maintenance interfaces and embedded platforms frequently include the exact types of data connections captured by the regulation’s statutory definitions.
Consequently, accurately assessing CRA applicability forces manufacturers to look far beyond simple internet connectivity. Engineering and compliance teams must holistically evaluate how a product is intended—or can reasonably be expected—to connect, communicate, and exchange data with external devices, peripheral hardware, or localized networks throughout its operational life.
Misconception 2: "Unchanged products can be resold indefinitely"
Another complex area of regulatory compliance involves understanding the legal distinction between "placing on the market" and "making available on the market." This differentiation carries significant weight for embedded products, which often remain commercially available and distributed off-the-shelf for many years after their initial design freeze.
Under the regulatory framework, products lawfully placed on the market prior to the primary CRA enforcement deadline of December 11, 2027, are generally permitted to continue circulating and being resold. Nevertheless, this exemption is not absolute. If an inventory unit or previously established product subsequently undergoes a substantial modification, it immediately loses its grandfathered status and must be brought into full compliance with the new CRA requirements before further commercial distribution.
Compounding this timeline are the CRA’s strict vulnerability and incident reporting obligations, which enter into legal force even earlier, starting on September 11, 2026. This staggered regulatory rollout means manufacturers cannot simply wait for the 2027 enforcement date. Organizations are actively required to track precisely when a product was introduced to the market, whether it has undergone any substantial engineering modifications, and how they will manage the mandatory incident-reporting mechanisms taking effect in late 2026.
Misconception 3: "Security support ends with product roadmaps"
Traditional commercial practices in the electronics sector rely heavily on internal product roadmaps, which typically dictate how long a manufacturer intends to actively market, sell, and support a particular hardware generation. However, the Cyber Resilience Act explicitly decouples cybersecurity obligations from these internal commercial timelines and marketing strategies.
Regardless of corporate sunset schedules or arbitrary commercial milestones, manufacturers are legally mandated to address discovered vulnerabilities and supply timely security updates throughout the entire statutory support period. For the vast majority of covered products, this mandatory support duration must span at least five years, unless the device’s expected operational lifecycle is demonstrably less than five years.
For embedded products, planning for this mandatory support window presents a significant logistical hurdle. The extended timeframe during which engineering teams must remain vigilant, patch vulnerabilities, and distribute security updates must be factored into financial and resource planning well in advance, separating long-term cybersecurity maintenance from conventional commercial end-of-life schedules.
How IEC 62443 can support CRA readiness
As organizations search for standardized methodologies to streamline their compliance workflows, established international frameworks offer valuable assistance. The IEC 62443 series of standards, for instance, provides a comprehensive cybersecurity framework covering secure development lifecycle processes and technical security requirements tailored for industrial automation and control systems.
While these established engineering processes can substantially bolster an organization’s internal security posture, industry experts caution that compliance with IEC 62443 alone does not automatically equate to legal compliance with the CRA. The two frameworks operate at different levels of regulatory and technical governance; they are complementary rather than interchangeable.
Therefore, manufacturers should view IEC 62443 as a foundational framework that facilitates CRA readiness rather than treating it as an alternative shortcut to CE marking. The standard’s rigorous approach to secure development and technical defense can seamlessly integrate into the broader compliance frameworks that companies deploy to meet the specific demands of the European legislation.
How COMs support CRA compliance efforts
In the realm of hardware architecture, computer-on-modules (COMs) offer a modular approach to embedded system design by physically separating the core processing module from the application-specific carrier board. This modular methodology naturally facilitates system upgrades across extended product lifecycles, while the adoption of open standards provides engineering teams with greater flexibility when managing inevitable component obsolescence and shifts in the global embedded supply chain.
Modern COMs also integrate robust hardware-level security features that directly contribute to secure-by-design principles. These native capabilities frequently include hardware and software roots of trust, advanced virtualization and system partitioning, robust data protection via secure local storage, and secure hardware maintenance utilities.
These technical capabilities form a reliable foundation that helps protect complex embedded systems against physical tampering and unauthorized access. Furthermore, they provide the underlying infrastructure necessary to securely deliver software updates and patches throughout the mandated support period without disrupting the broader application layer.
Component and module suppliers can further assist original equipment manufacturers by delivering comprehensive documentation and maintaining fully transparent development processes. Access to this detailed component-level intelligence empowers manufacturers to accurately evaluate the sub-assemblies integrated into their systems, thereby streamlining their overarching CRA compliance documentation.
Conclusion
Ultimately, hardware manufacturers bear the primary legal responsibility for ensuring that finished electronic products placed on the European market fully comply with the provisions of the Cyber Resilience Act, while importers and distributors maintain their own clearly defined supply-chain obligations.
From the earliest stages of architectural system development, manufacturers must proactively evaluate which product lines will fall under the CRA’s purview and establish clear pathways for delivering long-term security support. This comprehensive assessment must account for both the anticipated operational lifetime of the device and the exact calendar date it is first introduced to the commercial market.
While established standards like IEC 62443 and modular hardware paradigms like COM-based architectures can significantly ease the transition by providing proven security practices and flexible technical capabilities, the ultimate responsibility remains clear. The security, resilience, and integrity of the complete electronic system must be continuously maintained and defended throughout its entire defined support lifecycle.
