  1. Technically, an acronym needs to be or become an actual word, like “FIRST”, and an initialism is a shortening of a phrase or title into the initial character of each word. I tend to think of an acronym as being pronounceable, such SIEM, whereas an initialism is like EDR where we pronounce each character separately. For brevity, I’ll use acronym to refer to both. ↩︎
