About Muster
An independent readiness company, built on the government’s own math.
CMMC Level 2 is pushing capable small contractors out of the defense supply chain — not because they can’t be secure, but because the documentation and the $15,000–40,000 consultant quotes are out of reach. Muster exists to fix that: know your real SPRS score for free, then turn your own answers into the assessor-ready documents, at a fraction of the price and in days, without your data ever leaving your browser.
What we do
Score, then draft — from your answers, not a template
A free, no-signup self-assessment computes your exact SPRS score under the DoD Assessment Methodology and classifies every gap as POA&M-eligible or must-fix. From there, the platform drafts your System Security Plan and POA&M from the answers you gave — specific to your environment, conservatively worded, and traceable line by line. You review and approve; you stay in control.

The sources, cited openly
Nothing here is proprietary or invented. Muster is built directly on the primary government sources, so every claim is checkable against the original:
- NIST SP 800-171 Rev 2 — the 110 security requirements
- NIST SP 800-171A — the 320 assessment objectives behind them
- DoD Assessment Methodology — the weighted SPRS scoring
- 32 CFR 170.21 — POA&M eligibility and the conditional-status rules
- DoD CMMC Level 2 Assessment Guide — what a C3PAO examines
Our principles
How we operate
No CUI — ever
The platform is built so Controlled Unclassified Information never reaches it. The free assessment runs in your browser; file uploads are disabled by design; we work from descriptions of your systems, never their contents. It is the founding architectural choice, not a setting.
We draft, you attest
Every document is a draft generated from your own answers, for you to review, verify, and approve. We do not attest to your implementation status and we are not a certification — the judgment, and the responsibility, stay yours. That is what keeps you on the right side of the False Claims Act.
The government’s own math
We did not invent the scoring. Every number follows the published DoD Assessment Methodology, every eligibility call follows 32 CFR 170.21, and every generated statement traces to an answer you gave. An audit trail, not a black box.
Honest about what we are
Muster is an AI-native company — the assessment and drafting are done by software, openly, not by fake humans or invented testimonials. Independent, and not affiliated with or endorsed by the DoD or the Cyber AB. When we have real customer proof, it goes on the site; until then, the methodology and the math carry the page.
Company
The basics
Muster is an independent, U.S.-focused company serving small defense contractors and the consultants, RPOs, and MSPs who support them. We are not affiliated with, endorsed by, or sponsored by the U.S. Department of Defense or the Cyber AB; CMMC® is a registered trademark of the U.S. Department of Defense, used nominatively.
