World-Class Achievement: CYG Sunri Receives IEC 62443-2-4 Dual International Certification for Cybersecurity Services

On January 13, CYG Sunrui was awarded the IEC 62443-2-4 dual certification (TÜV Mark + CB) by TÜV SÜD Greater China. This marks a major milestone for CYG Sunrui in the field of power protection and automation, as it has now established a full-lifecycle cybersecurity system covering system design, development, integration, and maintenance. Its security management and execution capabilities have reached internationally advanced levels, providing solid support for expanding its global business presence.

The IEC 62443 series, developed jointly by the International Society of Automation (ISA) and the International Electrotechnical Commission (IEC), is the globally recognized security standard for industrial automation and control systems (IACS). Specifically, IEC 62443-2-4 defines the security capability requirements that service providers must meet during the integration and maintenance of industrial automation solutions, aiming to build safe and reliable service systems.

With this certification, CYG Sunrui has systematically established a service security framework covering key areas such as personnel competence, quality assurance, system architecture, configuration management, remote access, incident management, account management, malware protection, patch management, and backup/recovery. The company is now able to continuously implement and optimize cybersecurity strategies, providing clear guidance for integration service providers, maintenance service providers, and asset owners. This enhances the overall cyber protection of power protection and automation control systems, helping to ensure the stable operation of power systems.

After the certificate presentation, both parties held in-depth discussions on industry cybersecurity practices. TÜV SÜD spoke highly of CYG Sunrui’s professionalism and technical capabilities demonstrated during the certification process. Both sides look forward to deepening cooperation to drive high-quality development of technological innovation and security applications in the power industry.

This certification represents a significant step forward for CYG Sunrui in the industrial cybersecurity field, greatly strengthening the international competitiveness of its products and services and laying a solid foundation for the company’s deeper involvement in the development of new-type power systems worldwide.

Looking ahead, CYG Sunrui will continue to implement and refine the security standards and best practices established through this certification, applying them systematically to various engineering projects. At the same time, the company will actively integrate internationally recognized security standards such as IEC 62443 and IEC 62351, striving to provide global grid customers with safer, more efficient, and reliable intelligent total solutions, and to help safeguard the secure future of global energy infrastructure.
