01

Scope

We align on business context, environment boundary, target control set, and what review outcome matters.

  • Scope confirmation
  • Inheritance and assumptions
  • Assessment objective mapping

02

Evidence handoff

You provide artifacts through an agreed path. The first contact identifies the packet; sensitive evidence does not move through checkout.

  • Secure handoff path
  • Packet completeness check
  • No blind email dump
→
03

Findings packet

You receive clear findings that show contradiction risk, unsupported claims, and what to fix next.

  • Evidence integrity summary
  • Risk and contradiction notes
  • Prioritized actions

Hardseal does not certify compliance or replace a C3PAO.

Hardseal identifies evidence risk, gaps, and contradictions so teams can prepare better before formal review.

Prepare. Not attest.

§2.1 · The primitive

Hardseal proves a packet is internally consistent and matches a chain root you can verify.

§2.2 · Use cases

One primitive. Three surfaces.

CMMC Level 2 Evidence

Generate hash-chained, offline-verifiable evidence packages your assessor can verify offline (SHA-256 chain root, sidecar digest). A passing verification proves the pack is internally consistent and matches its expected root, not that its contents satisfy any control. See weak evidence before formal review.
