Yokogawa gains ISASecure CSA Level 1 Certification for ProSafe-RS Safety Instrumented System

07 June 2021

Yokogawa Electric Corporation has obtained ISASecure CSA Level 1 certification from the ISA Security Compliance Institute (ISCI) for its ProSafeTM-RS safety instrumented system, a product in the OpreX Control and Safety System family.

This is the first time a safety instrumented system has obtained this certification.

Yokogawa’s ProSafe-RS safety instrumented system is certified for use in safety integrity level 3 (SIL3) applications. With regards to cyber security, it has held ISASecure EDSA certification since 2013. Replacing this certification program, ISASecure CSA certifies compliance with the IEC62443-4-2 and IEC62443-4-1 international standards relating to control device security. Receipt of this certification indicates that a product has been recognised by a third-party as having security controls that conform to these international standards. 

Yokogawa also plans to obtain ISASecure CSA certification for the ProSafe-RS Lite SIL2 safety instrumented system, which was released in January of this year.

Through its development of secure control devices and systems as well as the provision of support services, Yokogawa offers its customers a wide range of security solutions. Yokogawa will leverage this certification to accelerate its efforts to enhance the cyber security of its customers’ plant operations.
