Have you read CSWP50? Its not exactly written on the 3rd grade level. I think its a pretty good compromise between something only your IT department can understand and what a small employer needs to know. If anything, it leans too technical and verbose.

Not only are there links to go deeper into each subject matter but also a part telling the employer how to hire help if they need cybersecurity help and with a link to the "Small Business Cybersecurity Support Programs Finder" directory. Ideally they should be asking around in the small business community for a local vendor, but this document does a lot of things right.

I think this is an excellent document for small business and doesn't really talk down to them.
