SINEXCEL wins IEC 62443-4-1 cybersecurity certification from TÜV SÜD

What was certified

SINEXCEL (300693.SZ) describes itself as a global provider of energy storage, EV charging and power quality solutions, as well as critical power infrastructure for AI-focused data centers (AIDC). According to the company, TÜV SÜD awarded the IEC 62443-4-1:2018 certification after an independent review of its system of cybersecurity-oriented product development processes, named Product Cybersecurity Development Process System V1.0.

SINEXCEL calls the certification a milestone that confirms its commitment to internationally recognized practices for secure product development. The announcement was issued from Shenzhen, China, on 23 October 2026.

Why the IEC 62443 standard matters

The company points out that industrial and energy systems are increasingly interconnected, which has made cybersecurity essential for operational reliability and resilience. The IEC 62443 series offers an internationally recognized framework for the security of industrial automation and control systems. It helps manufacturers put robust cybersecurity practices in place across the whole product life cycle.

According to SINEXCEL, the principles of the standard also provide a basis for meeting changing regulatory requirements and customer expectations. It names the EU Cyber Resilience Act (CRA), the NIS2 directive and NERC CIP, along with cybersecurity expectations in other international markets.

Eight areas assessed by TÜV SÜD

During the assessment, TÜV SÜD systematically evaluated SINEXCEL's cybersecurity development processes against IEC 62443-4-1:2018. The review focused on eight key areas:

• Security management
• Specification of security requirements
• Secure by design principles
• Secure implementation
• Security verification and validation testing
• Management of security-related issues
• Security update management
• Security guidelines for users

The evaluation confirmed that SINEXCEL's system meets the relevant requirements of the standard. It also creates a structured framework for integrating cybersecurity into product development and life cycle management, the company says.

Company statement and outlook

Marx Zhao, a cybersecurity expert at SINEXCEL, said in the announcement: "Cybersecurity is not just about meeting standards," in the company's wording, and described it as building security into every stage of product development. He added that the certification is an important milestone in strengthening secure development practices and helps customers navigate changing cybersecurity requirements in global markets.

SINEXCEL says the certification strengthens its basis for managing cybersecurity risk throughout product development and supports continuous improvement in security engineering, vulnerability management and protection across the life cycle. The company plans to keep promoting secure-by-design practices and to build up its cybersecurity capabilities to support reliable and resilient energy infrastructure worldwide.
