Practise data classification and sensitivity labels in LabelNinja.

hy I built LabelNinja

I built LabelNinja to keep my workshops interactive, and because I wanted to make data classification fun. It started as something just for my own sessions with clients — a way to let people practise the calls instead of walking a room through another slide with four coloured boxes.

It worked. People remember the labels because they had to choose them themselves, and get one wrong once or twice. The feedback was good enough that keeping it to myself stopped making sense, so it’s open to the community now.
