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
Tell us about your environment
A plain-English walkthrough of all 110 NIST SP 800-171 requirements, written for owners and IT managers. You describe your systems. You never enter 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 every word.
How it holds up
Built to be defensible, from the first answer to the final draft
File uploads are disabled by design. Competitors stand up GCC High enclaves to hold your data. With Muster there is no enclave to build.
No CUI, ever
The platform works from your description of how your systems operate, never their contents. File uploads are disabled by design, so nothing controlled leaves your browser to reach us. There is no enclave to build, and nothing of yours for us to lose.
The DoD's own math
We did not invent the scoring. Every deduction follows the published DoD Assessment Methodology, and every generated line traces back to the answer you gave. You can read the audit trail point by point.
You stay in control
What you get are drafts you review, verify, and approve before anything is filed. The judgment stays yours, which is exactly what keeps you on the right side of the False Claims Act.
Drafts you can defend
We are precise about what Muster produces: review-ready drafts and your calculated score, checked before they reach you. We never claim to hand you a certification, because no software honestly can. What we do hand you is documentation you can stand behind, with a source for every line.
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.
Pricing
A fraction of the consultant quote
Treat the consultant quote as the list price: firms charge $14,000 to $40,000 and make you wait months for these exact documents. One firm publishes $21,200 for the identical gap-assessment + SSP + POA&M bundle. Muster drafts them in days, for a fraction of that.

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 is the deliverable: your Sprint produces a complete, assessor-formatted SSP, a POA&M analyzed against 32 CFR 170.21, a CUI scoping memo, and your calculated SPRS score, every one QA-reviewed before it reaches you. If we don't deliver the full 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 eliminate the manual documentation work that bottlenecks your client capacity.
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. It is 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 from your descriptions of your environment. File uploads are disabled by design, and the rule is simple: describe how your systems work, not what they contain. Basic screens watch for obvious slips, and the design keeps 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, so 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, once 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. If you already work 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 real question is whether you start before or after the assessor waitlists double.

Twenty minutes from now you can have a clear estimate of your SPRS score and a map of which gaps stand between you and your next award.
