TURCK Earns Cybersecurity Certificate to IEC 62443-4-1

TÜV NORD certification confirms structured, secure development processes (Maturity Level 2)
TURCK has successfully certified its development processes for industrial automation and control systems to IEC 62443-4-1. The certification was issued by TÜV NORD and confirms the implementation of high security standards across the entire product development lifecycle.
TURCK achieved Maturity Level 2 (ML2)—evidence of structured documentation, implementation, and repeatable application of defined security measures in development. The result underscores TURCK’s commitment to security by design and creates added transparency and trust for customers worldwide.
Cybersecurity is a prerequisite for connected production. With IEC 62443-4-1 certification, we demonstrate that security is systematically embedded at TURCK, from requirements to end of life. Our customers receive products whose development is measurably aligned with international best practices.
What IEC 62443-4-1 Covers
IEC 62443-4-1 defines requirements for a Secure Development Lifecycle (SDL) for manufacturers, including:
Risk assessment & threat modeling: systematic identification of threats and vulnerabilities
Secure architecture & coding standards: guidelines for design, hardening, and reviews
Verification & validation: static/dynamic analysis, security testing, and penetration testing
Vulnerability & patch management: processes for reporting, triage, remediation, and distribution
Supply chain security & SBOM: controlled dependencies and component traceability
Coordinated Vulnerability Disclosure (CVD): structured collaboration with researchers and customers
Lifecycle maintenance: secure updates, traceability, and end-of-life rules
With ML2, TURCK demonstrates these activities are defined, documented, and repeatable across teams and product lines.
Value for Customers and Partners
Reduced risk in OT/IT environments through verifiably secured development processes
Faster audits via clear evidence, documentation, and standard-compliant artifacts
Predictable security updates and shorter response times in incident scenarios
Improved compliance readiness, including for regulated industries (e.g., automotive, pharma, food)
Milestone Toward the EU Cyber Resilience Act (CRA)
The certification is an important step toward the EU Cyber Resilience Act, whose requirements become binding from late 2027. Processes established under IEC 62443-4-1—such as risk and vulnerability management, secure update mechanisms, and SBOM—help customers meet future assurance obligations efficiently.
