Scope

How much of the standard Keel models

Models its declared scope in full

Keel authors every leaf requirement in the scope declared below, 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: 150+ requirements
In Keel’s scored scope: 150+ 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

How Keel helps with FedRAMP Rev5 Class B

Track FedRAMP Rev5 Class B 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 B shares canonical controls with FedRAMP Rev5 Class C, FedRAMP Rev5 Class D and NIST SP 800-53 and others in the catalog. Implement one of those controls and it counts toward every framework it satisfies, so adding FedRAMP Rev5 Class B rarely means starting from scratch.

A framework is lit when at least one canonical control satisfies both FedRAMP Rev5 Class B and that framework. Unlit means none of them do, which is an absence rather than a judgment about that standard.
