Scope

How much of the standard Keel models

Models its declared scope in full

Keel authors every leaf requirement in the scope declared below, all 322 of them, with nothing inside that scope left out. A test fails the build if the authored count and the declared count ever diverge, so this framework cannot quietly lose requirements after the fact.

Authored in Keel: 322 requirements
In Keel’s scored scope: 322 leaf requirements

Keel publishes this for every framework it ships, complete or not, so a readiness percentage can be read against a denominator you can see. Compare every framework

What Keel does

How Keel helps with FedRAMP Rev5 Class C

Track FedRAMP Rev5 Class C as a control set with a live readiness score
Crosswalked to your other frameworks, so shared controls are evidenced once
Collect evidence in one place and reuse it everywhere

Collect once, comply everywhere

FedRAMP Rev5 Class C is tracked as its own control set in the same place as everything else you have to prove, with the same owners, evidence, and review dates. Its requirements are specific enough that they do not yet share canonical controls with the other frameworks in the catalog.
