The International Society of Automation (ISA) Is a non-profit technical society for engineers, technicians, businesspeople, educators and students, who work, study or are interested in automation and pursuits related to it, such as instrumentation. Originally known as the Instrumentation Society of America, the society is more commonly known by its acronym, ISA. The society's scope now includes many technical and engineering disciplines.

ISA is one of the foremost professional organizations in the world for setting standards and educating industry professionals in automation. Instrumentation and automation are some of the key technologies involved in nearly all industrialized manufacturing. Modern industrial manufacturing is a complex interaction of numerous systems. Instrumentation provides regulation for these complex systems using many different measurement and control devices. Automation provides the programmable devices that permit greater flexibility in the operation of these complex manufacturing systems.

ISA is well known for its standards program, which surrounds topics in instrumentation, control systems, operational technology (OT) cybersecurity, and more. Prominent standards developed by ISA include:

• ISA/IEC 62443 series of standards, the world’s only consensus-based security standard for automation and control system applications
• ISA-95, Enterprise Control System Integration
• ISA-18.2, Management of Alarm Systems
• ISA-5.1, Instrumentation Symbols and Diagrams
