You may have seen ISG in a text message, work email, car manual, or online discussion and wondered what it means.
Unlike many internet abbreviations, ISG does not have one universal definition. Its meaning depends entirely on the conversation and the industry where it appears.

The most common meanings are Idle Stop and Go (an automotive feature), Information Services Group (a global technology research and consulting company), and Institute for Security Governance (a U.S. security cooperation organization). People rarely use ISG in casual texting compared to other abbreviations, so the topic of the conversation usually determines its meaning.
