IEC 62443-4-1
Cybersecurity from the start – verifiable across the entire product lifecycle
With certification to IEC 62443-4-1, manufacturers demonstrate that their Secure Product Development Lifecycle (SDL) effectively meets the requirements of the standard. This ranges from
- security requirements and ‘secure by design’ through
- verification and vulnerability management, right through to
- security update management.
It is not the individual product that is certified, but the development process from which it emerges. The maturity level achieved (ML2 to ML4) is stated on the certificate.
The certification is aimed at manufacturers of hardware and software for industrial automation and control systems, such as controllers, embedded systems, Industrial IoT solutions and cybersecurity products for industrial automation. It is suitable for companies that wish to make cybersecurity an integral part of their product development and demonstrate this independently to customers and business partners, particularly in light of the requirements of the Cyber Resilience Act.
Your benefits
Certification to IEC 62443-4-1 provides independent evidence that cybersecurity is not only documented but also effectively implemented in your product development. CIS Certification assesses this on the basis of random samples from your ongoing development projects.
- Verifiable evidence: The certificate clearly states the scope and maturity level and can be used as evidence for clients and business partners.
- Preparation for the CRA: Structured vulnerability and update management creates a solid foundation for meeting the requirements of the Cyber Resilience Act.
- Concrete suggestions for improvement: The audit report identifies strengths and areas for improvement as a basis for the further development of your SDL.
The certificate is valid for three years.
Annual surveillance audits – whether on-site, remote or a combination of both – ensure that your development process remains effective in the long term. An optional stage review allows you to check in advance whether your processes are ready for the targeted maturity level. Existing certificates from other accredited bodies can be recognised.
Cyber Resilience Act:
Why IEC 62443-4-1 is becoming increasingly important
With the Cyber Resilience Act (CRA, Regulation (EU) 2024/2847), binding cybersecurity requirements apply for the first time to products with digital elements placed on the market in the EU.
This applies to control systems and embedded systems as well as Industrial IoT solutions. Manufacturers must ensure cybersecurity throughout the entire product lifecycle: from risk-based development, through structured vulnerability management, to the provision of security updates throughout the entire support period. Reporting obligations for actively exploited vulnerabilities and serious security incidents have been in force since 11 September 2026. From 11 December 2027, all requirements will be mandatory and a prerequisite for CE marking. It is precisely these process requirements that IEC 62443-4-1 addresses. Certification provides a robust basis for systematically implementing the CRA requirements for development and vulnerability management, and for providing verifiable evidence of this to customers and regulatory authorities.
