Certified for secure product development

In October 2024, TÜV Rheinland, the German Technical Inspection Association in the Rhineland region of Germany, certified the secure product development process at Endress+Hauser in accordance with the IEC 62443-4-1 security standard, maturity level 3. Five product centers have received the certification and thus meet the requirements for the life cycle of the products.

The Council of the European Union passed the Cyber Resilience Act (CRA) in October 2024. This stipulates that products must demonstrate a high level of cybersecurity throughout their entire life cycle. Appropriate measures and methods must be implemented as early as the product development stage. Endress+Hauser follows this “Security by Design” approach to provide customers with the best possible support in protecting their systems. 

“We are particularly proud of this certificate as it recognizes our many years of effort to achieve the highest level of security in our product centers. This level of structured approach across many different development sites shows the importance Endress+Hauser places on cybersecurity,” says Mirko Brcic, Product Security Officer at Endress+Hauser.

One visible result of the cybersecurity measures is the development of secure access to Endress+Hauser measuring devices via Bluetooth. Even the internet standardization body IETF now recommends the CPace protocol used in the Endress+Hauser SmartBlue app for password-protected access.

In principle, a company that aligns its processes with IEC 62443-4-1 must prove that cybersecurity is incorporated throughout the entire life cycle of a product. As part of the group certification, the certifying body checks the following aspects, among others:

• Risk and threat analyses

• Security by design

• Security testing

• Vulnerability management

• Customer security manual

“With the IEC 62443-4-1 certification, we have jointly laid the foundation for supplying secure products in the future and being prepared for regulations such as the CRA,” says Mr Brcic. Five of the Group’s competence centers were certified: Endress+Hauser Flow, Endress+Hauser Level+Pressure, Endress+Hauser Liquid Analysis, Endress+Hauser Temperature+System Products, and Endress+Hauser Digital Solutions.
