Answer.

Certification / ATO evidence regime · CMMC.

A C3PAO assesses your implementation of the NIST SP 800-171 controls protecting CUI — for AI components that means audit logging (AU), system integrity and monitoring (SI), access control, and configuration management evidence around the model and its data. The assessor wants documented, repeatable proof, not assertions. Planisphere can produce the reproducible model-behaviour record that backs the SI/AU-flavoured controls; the C3PAO renders the assessment verdict, Planisphere does not.

Start with the free sandbox. Planisphere measures model behaviour and emits a reproducible, sha-pinned record — it does not certify, file, or give legal advice.

When CMMC asks for proof, hand over records — not assurances.

record the duty · seal the receipt · verify offline

Planisphere records each duty event — an output marked, a disclosure shown, a review made — and seals it into a receipt that verifies offline against our published keys. You send hashes, never content. A record is evidence a third party can check; it is not a certification and not a legal determination.
