Exercise in a Box is an online tool from the NCSC which helps organisations test and practise their response to a cyber attack.

It is completely free, and you don’t have to be an expert to use it. The service provides exercises, based around the main cyber threats, which your organisation can do in your own time, in a safe environment, as many times as you want. It includes everything you need for setting up, planning, delivery, and post-exercise activity, all in one place.
