The concept of shadow IT is by no means new, it is a decades-old phenomenon that gained momentum with the advent of cloud services and the spread of increasingly advanced computing devices among a wide range of users (especially with the advent of smartphones, laptops, tablets - cf. the so-called "Bring Your Own Device", BYOD phenomenon, which also entailed serious internal regulatory challenges for businesses).
More recently, and mainly after ChatGPT became available in November 2022, we have become familiar with another subset of shadow IT phenomena: the threat of using "shadow AI", i.e. the use of unapproved, unverified artificial intelligence (AI) applications.
