Securing your digital plant: Protecting operations, and building cyber resilience

Cyberattacks are evolving rapidly, targeting not just IT systems but also operational technology. As previously isolated field devices, control systems, and networks become more interconnected, every new interface can become a potential entry point for attackers. Introducing a whole new causality for unplanned downtime, equipment damage, and safety risks.   

Beyond just the risk of attacks, cybersecurity legislation and industry requirements are tightening worldwide. Standards such as IEC 62443 and regulations like NIS2 place responsibility directly on operators to demonstrate secure operations across the entire lifecycle of their plant.  

As we step into the future of digitalization and process automation, the need for secure and compliant digitally enabled instrumentation is clear. But digitally enabled instrumentation is nothing without secure data exchange. Whether configuring field devices, collecting real-time diagnostics, or enabling remote support, secure connectivity is the foundation for both efficiency and security.  

Endress+Hauser has established a secure and efficient wireless communication protocol tailored for the conversion of the IT and OT environments. Our Bluetooth ® connectivity redefines how engineers interact with devices in the field. By introducing CPace as a security layer for Bluetooth®, password protection is strengthened and attacks on Bluetooth® pairing steps are prevented. 

Benefits include: 

• Secure device interaction: Encrypted Bluetooth® connectivity based on CPace protects credentials and device access during configuration and monitoring. 
• Protection against advanced attacks: Asymmetric cryptography prevents phishing and man‑in‑the‑middle attacks during wireless communication. 
• Safer maintenance activities: Secure wireless access reduces the need for physical intervention in hazardous or hard‑to‑reach areas. 
• Reduced infrastructure effort: Wireless connectivity lowers infrastructure effort while improving usability and time efficiency in daily plant operations. 
• Operational efficiency gains: Faster workflows help operators work more securely while reducing downtime. 

By leveraging secure wireless connectivity, such as Bluetooth®, you help reduce risk at the point where cybersecurity is often weakest, the field level. All while enabling digital workflows that increase efficiency and safety. 

For decades, we have supported customers in safely adopting new technologies – from the first generation of digital sensors to today’s cloud connected systems. Our approach to cybersecurity is rooted in industrial requirements, global standards, and with the evolving digital landscape, secure by design principles. 

We pride ourselves on protecting our customers by building security into our products and solutions from the start, following a certified secure development lifecycle that adheres to IEC 62443-4-1. Furthermore, our IIoT ecosystem follows international standards such as ISO 27001 and ISO 27017, ensuring secure data handling across the entire value chain. 

Endress+Hauser’s Bluetooth® technology enables the digitalization of your plant. Embedded into a large selection of our product portfolio, the technology is designed to ensure secure, low-energy connectivity from your field devices to your control system.  

At Endress+Hauser, we want to deliver more than just instrumentation. We drive to provide smart, secure solutions that empower your plant with secure, efficient digital workflows that drive lasting value.
