They are actually made by a company they bought, Twist and Shout (https://www.twistandshout.co.uk) :-)

The Inside Man is entertaining, but as the "show" progresses, it becomes progressively more a standard sitcom and less about security training. Past the first season, there are entire episodes which are mostly like a Netflix show, with a last minute message of "oh, and remember: never leave your laptop unlocked" tacked on.

Entertaining? Yes. Useful as a training? Ehhh...
