IEC 62443-4-1

International Quality Management System Certification

Aligned with International Secure Development Lifecycle Standards to Strengthen Industrial Product Cyber Resilience

WeLink Solutions, a trusted provider of intelligent industrial control and edge computing solutions, proudly announces that its product development process has been officially certified with IEC 62443-4-1:2018, the international standard for Secure Product Development Lifecycle (SDL / SPDLC) in industrial automation and control systems.

This achievement confirms that WeLink’s R&D processes and cybersecurity governance are fully aligned with globally recognized OT / ICS cybersecurity standards, establishing a stronger, safer, and more sustainable digital foundation for critical applications such as smart manufacturing, AIoT, energy, transportation, and smart city infrastructure.

What is IEC 62443-4-1?

The Global Standard for Secure Industrial Product Development
  • IEC 62443-4-1 is one of the most authoritative cybersecurity standards for Industrial Automation and Control Systems (IACS / ICS). It defines security requirements for product suppliers across the entire product lifecycle, including security requirements definition, design, implementation, verification, vulnerability management, and security updates. Achieving IEC 62443-4-1 certification demonstrates that an organization has established an auditable, sustainable, and “Security by Design” development framework, enabling vulnerabilities to be reduced at the source while strengthening supply chain trust.

WeLink’s R&D Philosophy: Security Builds Trust, Trust Shapes the Future

At WeLink, “Security as Trust” is a core principle. Industrial cybersecurity is embedded directly into our Secure Product Development Lifecycle (SPDLC), ensuring that every generation of our products delivers long-term protection and operational stability in demanding industrial environments.

How WeLink Implements Secure Development Lifecycle (SDL)

Security by Design

Security is integrated from the architectural stage through threat modeling, attack surface analysis, and security requirement definition, shifting cybersecurity considerations to the earliest phases of development.

Security Coding Practices

We adopt static application security testing (SAST), dynamic application security testing (DAST), and secure coding checklists to minimize software and firmware vulnerabilities.

Configuration & Change Control

Strict version, configuration, and change management ensure full traceability and controlled modifications throughout the product lifecycle—enhancing the long-term maintainability of industrial computers and embedded systems.

Vulnerability Management & PSIRT

From reporting and analysis to remediation, validation, and disclosure, our vulnerability handling process is fully institutionalized to ensure rapid response to emerging OT cybersecurity threats.

Comprehensive Security Documentation

Complete security documentation and development records improve transparency, auditability, and consistency—ensuring that even customized solutions maintain the same high cybersecurity standards.

Customer Value: Cybersecurity Protection from the Source

Choosing a supplier certified to IEC 62443-4-1 means your industrial systems are built on trusted and proven security processes.

Reduced Vulnerability Risk at the Source

All WeLink products follow SDL / SPDLC practices from initial design, systematically lowering the likelihood of security weaknesses.

Alignment with Global Supply Chain Security Requirements

IEC 62443-4-1 has become a key qualification criterion for industrial cybersecurity procurement. Certification reflects WeLink’s international-grade R&D capability and security governance.

Enhanced Cyber Resilience with Lower Operational Risk

WeLink’s edge computing and embedded platforms are designed for continuous threat resistance, reducing risks of downtime, data leakage, and system compromise.

Supporting ESG and Sustainable Governance

Cybersecurity is a pillar of operational resilience. IEC 62443-4-1 strengthens product lifecycle sustainability, helping customers advance ESG and long-term governance objectives.

International Certification by an Accredited Authority

WeLink’s secure development process has been certified by TÜV NORD Taiwan Co., Ltd., confirming full compliance with international industrial cybersecurity standards and demonstrating WeLink’s long-term commitment to industrial security, product safety, and supply chain responsibility.
