No-call buyer path: Scope brief → pay or invoice → secure handoff
$5,500 one-time Evidence Integrity Review. Start with scope first. Hardseal does not certify compliance or replace a C3PAO.
CMMC Level 2 · NIST SP 800-171

Find weak evidence before formal review.

Hardseal reviews CMMC evidence packets for unsupported claims, contradiction risk, AI/boilerplate artifacts, and integrity breaks before teams rely on them.

SSP vs. evidence gaps Unsupported control claims AI and boilerplate risk Governed evidence handoff

Evidence review for CMMC teams.
$5,500
One-time B2B review. Start with the scoping brief; payment or invoice happens after the packet boundary is clear.
  • SSP, POA&M, SPRS, policies, screenshots, tickets, exports, and control evidence.
  • Findings packet showing supported, partial, contradicted, and missing evidence.
  • Pre-assessment support only. Hardseal does not certify, assess, or guarantee compliance.
Build scoping brief Need invoice first?

Want proof first? Use the browser verifier below or inspect a sample packet before you start.

01

Scope

Generate the scoping brief so the packet, owner, framework, and review boundary are clear before any evidence moves.

  • Scoping brief
  • Inheritance and assumptions
  • Assessment objective mapping
→
02

Pay or invoice

Use card, invoice, PO, W-9, or vendor workflow after the review shape is clear. Stripe is a payment rail, not a file-transfer rail.

  • Stripe or invoice
  • Procurement details
  • No blind checkout
→
03

Secure handoff

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

  • Evidence handoff path
  • Packet completeness check
  • No blind email dump

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.
60-second proof

Verify the primitive before you buy the review.

Hardseal does not ask you to trust a screenshot. Download a sample receipt, paste it into the verifier, and watch the packet prove whether it still matches its recorded chain.

Download sample receipt

Use the same public sample packet behind the live verifier and trust ledger.

02

Paste in verifier → PASS

The browser recomputes the SHA-256 chain locally. No upload, no account, no sales call.

03

That is the packet test

The paid review applies the same discipline to your CMMC evidence before formal review.

INDEPENDENT VERIFICATION · CLIENT-SIDE · NO UPLOAD

Verify the proof primitive before you buy the review.

Drop a packet, paste a SHA, or upload evidence. The verifier runs in your browser. The math is the witness.

§2.1 · Primitive + governance

Hardseal is a verification primitive with a governance path around it: prove what copy you have, control how evidence moves, and name what must be fixed before formal review.

Primitive

Hash chains, sidecar digests, and browser or Python verifiers answer the first question: does this copy still match the recorded packet?

Open verifier →
Governance

Scope confirmation, handoff rules, owner checks, sensitive-evidence warnings, and stop conditions keep the review from becoming an uncontrolled file dump.

See client path →
Review layer

SSP, POA&M, SPRS, and control evidence are compared for unsupported claims, partial support, contradiction risk, and the next proof needed.

§2.2 · Use cases

One primitive. Three governed 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.
