Shadow IT
Software the business depends on that nobody in charge knows about.

What it means
Shadow IT is technology adopted by individuals or teams without central approval — a free file-sharing account, a personal subscription, a spreadsheet that became a system.
Why it matters
It usually exists because the sanctioned tool did not do the job, so it is information as well as a risk. And it holds company data outside any control.
What it looks like in practice
Find it by asking rather than by scanning: what do you use that IT does not know about, and why. People answer honestly if the question is not a disciplinary one.
What to watch out for
Data leaving with the person who set it up, and no backup, no access control and no contract behind a system the business now depends on.
Where to get proper advice
Your own team. The NCSC on acceptable use policies.
