Penetration Testing for the Cyber Resilience Act
By Ben DiMolfetta
The Cyber Resilience Act (CRA) is introducing a new standard of accountability for all products with digital elements entering the EU market. It requires manufacturers, importers, and distributors to follow defined cybersecurity obligations that begin taking effect in 2026 and become fully enforceable in December 2027. These obligations include secure design requirements, vulnerability reporting timelines, and lifecycle documentation for software and hardware products.
For organizations that produce or distribute connected systems, the CRA is not a minimal paperwork exercise. It is a comprehensive regulatory framework that demands proof that security is part of product architecture, testing, and maintenance. This includes mandatory vulnerability management, secure default configurations, risk-based development processes, and rapid reporting of actively exploited vulnerabilities.
Many penetration testing vendors continue to operate with traditional methodologies that do not map cleanly to CRA requirements. These approaches typically focus on testing a single build or a single release cycle without demonstrating how vulnerabilities are identified, retested, documented, and validated through the entire product lifecycle. Under the CRA, this is no longer enough.
How CRA aligned penetration testing differs
CRA aligned penetration testing is more than a technical assessment. It is a structured approach that covers how digital products are secured from the design phase through their end of support. This requires testing that evaluates not only the presence of exploitable flaws but also the developer and manufacturer processes that contribute to overall security posture. The CRA mandates secure by design development, long term support, and transparent security characteristics, which means the testing model must reflect these expectations.
Testing must also support CRA specific requirements such as documentation of vulnerability handling and readiness for reporting obligations that begin on September 11, 2026. These obligations require organizations to disclose actively exploited vulnerabilities within 24 hours and provide follow up reporting within 72 hours. Penetration testing must therefore validate that organizations can detect, address, and report vulnerabilities in a timely way.
Why organizations choose Winmill for CRA readiness
Winmill’s Penetration Testing Stream is purpose-built for environments where compliance and ongoing security maturity must work together. The program provides recurring testing that aligns with product development cycles and lifecycle expectations defined by the CRA.
Unlike snapshot testing models, our approach provides evidence that cybersecurity practices are maintained over time. This helps organizations demonstrate conformity with the CRA requirement for ongoing vulnerability management and lifecycle security updates. Our testing aligns to the CRA goal of reducing design stage vulnerabilities and increasing transparency of security risks throughout the lifespan of digital products.
Our consultants also support teams that must prepare for conformity assessments. Products classified as higher risk may require evaluation by notified bodies beginning June 11, 2026. Internal processes and technical controls must be documented and validated in line with CRA guidance.
Preparing for CRA also prepares you for better security
The CRA is raising expectations for product security. Organizations that take steps now to validate their security controls, document their processes, and confirm their vulnerability remediation capabilities will be better positioned to avoid compliance gaps when enforcement begins. Testing programs that reflect real lifecycle expectations give manufacturers and distributors confidence as they move toward the December 2027 full compliance date.
