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 287 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: 287 requirements
In Keel’s scored scope: 287 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 NIST SP 800-53

Track NIST SP 800-53 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

NIST SP 800-53 shares canonical controls with ISO/IEC 27001, HIPAA and SOC 2 and others in the catalog. Implement one of those controls and it counts toward every framework it satisfies, so adding NIST SP 800-53 rarely means starting from scratch.
