What's the difference between ATO and NIST SP 800-53 Rev. 5?

ATO (Authorization to Operate · program-office citation) and NIST SP 800-53 Rev. 5 (controls baseline · 20 families · AI overlays) are distinct cite-anchors. Planisphere's evidence record maps both controls for evaluator review; sufficiency remains evaluator-specific.

Do I need both ATO and NIST SP 800-53 Rev. 5 in my record?

If both apply to your tool deployment, yes — and the record maps both controls in one artifact at no extra cost.

Both at once.

The evidence record maps both anchors for review — you don't have to pick.

Planisphere's evidence record is multi-control by construction. ATO and NIST SP 800-53 Rev. 5 are both keys in the record's requirement list; the same SHA-pinned, Merkle-rooted artifact gives both evaluators a shared review record.

The requirement list is open — add any standard the regulator names. See the full compliance-control register.
