This looks potentially very useful, thanks for sharing!

There appear to be several of these worth investigating. Ordered by highest to lowest apparent activity level and update frequency:

https://github.com/aquasecurity/kube-bench (Go)

https://github.com/neuvector/kubernetes-cis-benchmark (Bash)

https://github.com/dev-sec/cis-kubernetes-benchmark (Ruby)

I'll add https://github.com/nccgroup/kube-auto-analyzer to that list (disclaimer, I for my sins, wrote it :) )

This is quite useful, thank you for pointing me in this direction!

Super useful thanks, added it to the guide
