exida has been built upon
sound engineering principles
in the quest for a safer world.

About Us.

exida was founded in 1999 by Dr. William Goble (USA) and Mr. Rainer Faller (Germany). Goble and Faller are considered by many to be the leading authorities in the field of functional safety.

They recognized the growing need for companies operating in the safety domain to become more knowledgeable about the requirements for safety related applications.

exida has evolved from two offices in the US & Germany to a global support network.

exida provides expert end user and OEM system consulting, product testing and certification, assessment, cybersecurity, and alarm management services to clients ranging from Fortune 500 to small start-up companies.

exida can guide you through the complex issues of functional safety, cybersecurity, and alarm management.

exida provides qualified customers with certification to a number of functional safety and security standards, such as IEC 61508, IEC 61511, ISO 26262, ISO 13849, IEC 62061, and the ISA Security Compliance Institute (ISCI).

exida has certified more process safety devices to IEC 61508 than any other agency worldwide.

exida’s engineers participate and have voting rights on the IEC and ISA committees and regularly speak at leading industry conferences.

As a result of its involvement in key safety committees, exida is at the forefront of the industry in developing training, tools, and knowledge resources to help you better understand and measurably improve the safety, security, and reliability of your processes and automation systems.
