CIS-CAT Pro Assessor v4 strives to be a standards-based application focused on vendor-supported technology
platforms where OVAL coverage is available. For example, most older benchmarks developed using CIS' proprietary Embedded Check
Language (ECL) will not be moved forward into v4 and will eventually be archived due to their age and diminishing relevance.
If v3 contains a Benchmark that v4 does not, we encourage you to use v3. Our primary objective in the coming year will be to
increase v4’s CIS Benchmark coverage to align with the supported versions of CIS Benchmark content where OVAL coverage exists.
