We have previously recommended the NCSC’s Small Charity Guide as a way of benchmarking your cybersecurity plans.
The National Cyber Security Centre has launched a replacement, being the Cyber Action Toolkit. It offers a layered (Foundation, Improver and Enhanced) approach and a customised toolkit based on three simple questions.
We commend it, and suggest that it will help you to benchmark and updated your cybersecurity plans. You can access the Cyber Action Toolkit with the link https://cybertoolkit.service.ncsc.gov.uk/.
