Thanks for the update RoleReversal,
Iit would be curious to run both tools on the same config and compare the results. I tend to think of the CIS as sort of a "standard" or "best practices" for benchmarks... from their website:
How are the CIS Benchmarks created?
The CIS Benchmarks are created through a consensus based process involving dozens or hundred of experts from around the world and each of the three major sectors: government, private industry, and academic institutions.
These experts meet virtually through email lists and teleconferences facilitated by CIS to discuss security configuration recommendations that comprise a CIS Benchmark. Because agreement doesn't always come easy, this process can take anywhere from weeks to months.
In the end, this unique process helps to create comprehensive security guidance that is applicable to a wide audience.
