SGS Assists TXOne Networks in Completing IEC 62443-4-1 Verification

The rapid rise of Industry 4.0 has blurred the lines between Information Technology (IT) and Operational Technology (OT). This deep integration drives massive efficiency gains, but it also opens the door to sophisticated cyberattacks against our most vital infrastructure. From energy to transportation, the increasing frequency of these threats has transformed industrial cybersecurity into a strategic priority. Today, a company’s ability to secure its control systems is a direct measure of its operational resilience and its competitive edge in the global market.

 

SGS, the global leader in testing, inspection, and cerification, recently supported TXOne Networks, a leading provider of industrial control system cybersecurity solutions, in successfully achieving the IEC 62443-4-1 Secure Product Development Lifecycle certification. TXOne Networks has officially obtained the IECEE CB Certificate, underscoring its world-class capabilities in developing secure industrial control system cybersecurity products.

 

IEC 62443: The Global Standard for Industrial Control System Cybersecurity

The IEC 62443 series of standards provides a comprehensive cybersecurity framework specifically designed for Industrial Automation and Control Systems (IACS). It is widely applied across critical industries, including manufacturing, semiconductors, energy, transportation, and healthcare. Within this framework, IEC 62443-4-1 focuses on cybersecurity processes throughout the product development lifecycle, requiring manufacturers to systematically implement security requirements analysis, threat modeling, vulnerability management, and other essential processes and mechanisms across the entire lifecycle.

As global awareness of industrial control system cybersecurity continues to grow and cybersecurity regulations become increasingly stringent in the EU and other regions, achieving IEC 62443 certification has become a critical prerequisite for industrial control products to enter international markets and build customer trust.

 

SGS, Building Cybersecurity Capabilities Trusted by Global Markets

SGS, globally recognized as a benchmark for quality and integrity, operates a worldwide network for testing, inspection, and verification, and brings extensive expertise in industrial control system cybersecurity standards. In this project, SGS leveraged its deep understanding of the IEC 62443 standard and its practical experience within the IECEE framework to support TXOne in systematically reviewing its secure product development processes. This approach ensured that both process design and implementation were fully aligned with international standards and third-party verification requirements, ultimately leading to a successful assessment and the attainment of CB certification.

 

TXOne specializes in industrial control cybersecurity and has earned the trust of the industry.

TXOne Networks was founded by a team with deep expertise in cybersecurity and a strong focus on industrial OT security. The company has long served high-risk industries such as semiconductor manufacturing, automotive manufacturing, precision manufacturing, pharmaceuticals, and critical infrastructure. Its cybersecurity solutions, designed to operate without impacting production lines, have earned widespread recognition from customers worldwide.

Achieving IEC 62443-4-1 certification not only reaffirms TXOne’s technical strength and process maturity in industrial control system cybersecurity, but also establishes a stronger foundation of compliance and trust, supporting its expansion into international markets including Europe, the United States, and Japan.

 

Working Together to Advance Industrial Control Cybersecurity Alignment with International Standards

SGS stated that it will continue to leverage its global verification capabilities and localized professional services to support a growing number of Taiwanese and international industrial control equipment and product suppliers in addressing evolving international cybersecurity regulatory requirements, including IEC 62443 and the EU Cyber Resilience Act (CRA). Through these efforts, SGS aims to enhance product security resilience and strengthen market competitiveness.

Through its successful collaboration with TXOne, SGS has once again demonstrated its leadership in industrial cybersecurity verification. Working alongside industry partners, SGS remains committed to building a safer and more trustworthy digital future for the industrial sector.
