Teradyne Robotics achieves IEC 62443-4-1 ML3 certification

As industrial automation becomes increasingly connected, cybersecurity has moved from an IT consideration to a critical operational requirement. Manufacturers, integrators, and machine builders are being asked to demonstrate not only that their systems are secure today, but also that security is embedded into the way those systems are developed, maintained, and improved over time. 

Today, Universal Robots is proud to announce that Teradyne Robotics has achieved IEC 62443-4-1 Maturity Level 3 “ML3” certification, marking an important milestone in our commitment to delivering secure, future-ready automation solutions across both Universal Robots and MiR 

What is IEC 62443-4-1? 

IEC 62443 is widely recognized as the leading international cybersecurity framework for industrial automation and control systems. The IEC 62443-4-1 standard focuses specifically on the secure development lifecycle of software and products, defining how organizations design, build, test, maintain, and update products with cybersecurity in mind.  

IEC 62443-4-1 examines the processes behind product development, including: 

• Security management and governance 

• Security requirements and risk assessment 

• Secure-by-design architecture 

• Secure implementation and coding practices 

• Verification and validation testing 

• Security issue and vulnerability management 

• Security update management 

• Security guidance and hardening documentation 

These practices help ensure that cybersecurity is considered from the earliest design stages through deployment and ongoing maintenance.  

Why ML3 matters 

Maturity Levels in IEC 62443-4-1 describe the consistent application of security processes in product development by a manufacturer, While previous certifications validated secure development practices across Teradyne Robotics, ML3 proves the capability of consistently developing and releasing products with security capabilities required by technical certifications such as IEC 62443-4-2.  

Achieving ML3 demonstrates that security processes are not only documented and implemented, but are consistently applied, measured, and continuously improved. For customers, this provides independent verification that cybersecurity is not treated as an afterthought or a one-time project, but as an integral part of the software development lifecycle.  

Security built into the foundation of PolyScope X 

Cybersecurity depends as much on architecture as it does on processes. PolyScope X was designed as a modern, modular platform built to support continuous improvement through software updates and evolving security capabilities. Internal company materials describe PolyScope X as a platform designed for continuous updates, modern integration requirements, and long-term cybersecurity evolution.  

This approach is increasingly important as manufacturers navigate new regulatory requirements, tighter customer cybersecurity expectations, and the growing need to connect robots with plant-wide systems, cloud platforms, and business applications. 

By combining a modern software architecture with independently verified secure development practices, PolyScope X provides a stronger foundation for organizations seeking to deploy automation in connected environments.  

Confidence for customers, integrators, and developers 

For manufacturers and system integrators, cybersecurity certifications provide more than technical validation. They offer evidence that can support risk assessments, procurement requirements, customer audits, and compliance initiatives. 

Certifications such as IEC 62443-4 provide externally validated proof and evidence of the capabilities of the manufacturer to produce secure products. Such third-party validations move the trust beyond vendor claims and demonstrates responsibility and continued commitment to producing secure products. 

As cybersecurity regulations continue to evolve globally, organizations increasingly need partners that can demonstrate both secure products and secure development processes. The achievement of IEC 62443-4-1 ML3 certification reinforces Universal Robots' position as a trusted automation provider focused on helping customers confidently adopt advanced robotics technologies.  

Looking ahead 

The achievement of IEC 62443-4-1 ML3 certification is another step in Universal Robots' broader cybersecurity journey toward compliance with the Cyber Resilience Act. As connected automation continues to expand across industries, cybersecurity will remain a core design principle for PolyScope X and future software innovations. 

For customers, the result is simple: greater confidence that the software platform driving their automation solutions is developed using independently verified cybersecurity practices designed for today's connected industrial environments.
