What's an SPRS score, and why do primes keep asking?
Your Supplier Performance Risk System score (-203 to 110) is how DoD tracks your NIST SP 800-171 self-assessment. Contracting officers check it, and primes are required to confirm their subs have a current one — which is why the request keeps landing in your inbox. A wrong score is a False Claims Act risk; a low score is a lost award. Knowing your real number is step one.

From "where do we even start?" to assessor-ready
Answer questions about your environment
A guided discovery across all 110 NIST SP 800-171 requirements — written in plain English for owners and IT managers, not compliance lawyers. Descriptions only; never CUI.
See your real SPRS score
The exact DoD Assessment Methodology math: weighted deductions, partial-credit rules, and which gaps are POA&M-eligible versus must-fix under 32 CFR 170.21.
Get assessor-ready documents
A draft System Security Plan and POA&M built from your answers — specific to your environment, conservatively worded, and QA-reviewed before delivery. You review and approve; you stay in control.
Why you can trust this
Built for a buyer who distrusts flashy AI startups and cheap-looking tools
File uploads are disabled by design. Competitors stand up GCC High enclaves — with Muster you don't even have to.
No CUI, ever
The platform works entirely from your descriptions of your environment. File uploads are disabled by design — describe systems, never their contents. Nothing controlled ever leaves your browser to reach us.
The DoD's own math
We did not invent the scoring. Every deduction follows the published DoD Assessment Methodology, and every generated statement traces back to the answer you gave — an audit trail, not a black box.
You stay in control
What you get are drafts you review, verify, and approve before anything is used — not auto-attestations. The judgment stays yours, which is exactly what keeps you on the right side of the False Claims Act.
Honest about what we are
Drafts, not certifications. An AI team doing the documentation work, not fake humans or invented testimonials. When we have real proof, it goes here — until then, the methodology and the math carry the page.
Sources we build on, cited openly: DoD Assessment Methodology, 32 CFR 170.21, NIST SP 800-171 Rev 2. We didn't invent the math — DoD did.

The Muster Readiness Guarantee
We can't guarantee a federal assessor's decision — no honest vendor can, and anyone who does is selling you something. What we do guarantee: your Sprint delivers a complete, assessor-formatted SSP, a 32 CFR 170.21–analyzed POA&M, a CUI scoping memo, and your calculated SPRS score — every artifact QA-reviewed before it reaches you. If we don't deliver the full artifact set as described, you don't pay: 30 days, full refund, no questions. Built against the published 320 assessment objectives.
Consultants, RPOs & MSPs: white-label the Muster engine from $3,000/yr + $200/client/mo — and stop hand-writing the documentation hours that cap how many clients each practitioner can carry.
Methodology transparency
We didn't invent the scoring — DoD did
Every number on your scorecard comes from the published DoD Assessment Methodology: weighted deductions, partial-credit rules, and the 32 CFR 170.21 eligibility test for which gaps can sit on a POA&M. No proprietary black box — just the government's own math, applied consistently and shown openly, with an audit trail from each answer to each generated statement.

The questions buyers actually ask
Is this legal advice or a certification?
No. Muster drafts compliance documentation from information you provide and computes your score under the published DoD methodology. Certification comes from a C3PAO assessment; attestation is yours. We make you ready for both, faster and far cheaper than hourly consultants.
Do I upload my files or system data?
Never. The platform works entirely from your descriptions of your environment. File uploads are disabled by design, and the rule is simple: describe systems, never their contents. Basic screens watch for obvious slips, but the responsibility and the design both keep CUI out of the platform entirely.
What is an SPRS score and why does it matter?
The Supplier Performance Risk System score (-203 to 110) is how DoD tracks your NIST SP 800-171 self-assessment. Contracting officers check it, and primes are required to make sure their subs have a current one — which is why they keep asking you for it. A wrong score is a False Claims Act risk; a low score is a lost award. Knowing your real number is step one.
Try the free SPRS score calculator →My consultant quoted $30,000 and a 4-month start date. How are you different?
Consultants hand-write the same artifact types our engine assembles from your structured answers — at $250–400/hour, when you can get on their calendar. We deliver draft documentation in days at a fixed price, with an audit trail of where every statement came from. And if you're already working with a consultant or RPO, bring them our drafts: documentation hours are usually the bulk of their quote.
What happens after Nov 10, 2026?
Phase 2 makes C3PAO-assessed Level 2 the default condition of award for contracts involving CUI, rolling out solicitation by solicitation through 2028. If CUI touches your work, the question is not whether you need this — it is whether you start before or after the assessor waitlists double.

Every week you wait, the waitlist grows
Twenty minutes from now you can have an honest estimate of your SPRS score — and a map of exactly which gaps stand between you and your next award.
