CMMC software, compared: Muster vs Vanta vs Drata
Short version: Vanta and Drata are excellent SOC 2-first GRC platforms that have added real CMMC support — a strong fit if you already run them, your stack is cloud-native, and you want continuous monitoring across many frameworks. Muster is built for the small defense contractor who just needs the SSP, POA&M, and a real SPRS score — without ingesting any CUI, and at a one-time $4,995 instead of a $7,500+/year subscription. We'll show you the differences so you can pick honestly — including where they beat us.

Where each one wins
Vanta is the call when…
…you already use Vanta for SOC 2, or your IT is cloud-native. It connects 400+ integrations, carries a 4.6/5 average across thousands of G2 reviews, and in May 2026 added real-time SPRS auto-tracking plus OSCAL export for federal artifact requests. If your controls already live in the tools Vanta plugs into, adding its CMMC module is the obvious move — and its CMMC coverage is no longer superficial.
Drata is the call when…
…you want one relationship that bundles the platform with human help. Drata supports CMMC across all tiers (Essential starts at $7,500/year) and pairs it with the BARR Advisory CMMC accelerator, so you get software plus a consulting hand in one place. For a mid-market team that wants guidance alongside the tooling, that's a real edge.
Muster is the call when…
…you're a small defense contractor who needs the documents, not a platform to live in. Your IT is probably on-prem Active Directory and a VPN, not a cloud-native stack to integrate. You don't want CUI leaving your network, and you'd rather pay once than carry a yearly subscription. Muster scores you for free, drafts your SSP and POA&M from your own answers, and never ingests a byte of CUI — the work happens in your browser. You can start in the next five minutes without a demo.
A simple way to choose
If you already run Vanta or Drata for SOC 2 and your systems are cloud-native, turn on their CMMC module — you've paid for the platform, and the integrations do real work.
If you're a sub-50-person defense shop whose IT is mostly on-prem, who handles a limited amount of CUI, and who needs an assessor-ready SSP, a 32 CFR 170.21 POA&M, and a defensible SPRS score without a managed enclave or an annual contract — that's the gap Muster was built for. The two aren't really competing for the same buyer.
One thing that's true whichever you pick: none of these tools certify you. They get you ready; an authorized C3PAO does the assessment. Budget the assessment fee separately — see the honest cost breakdown for the numbers.
Straight answers
Is Muster a replacement for Vanta or Drata?
Not exactly — they solve a wider problem. Vanta and Drata are broad GRC platforms built first for SOC 2 and ISO 27001, with continuous, integration-based monitoring across many frameworks. Muster does one thing: get a small defense contractor through CMMC Level 2 readiness — the SPRS score, the SSP, the POA&M — without ingesting your data or locking you into a yearly contract. If you need multi-framework monitoring and your stack is cloud-native, their platforms fit. If you need the CMMC documents and your number, Muster is built for exactly that.
Which is cheapest for CMMC Level 2?
On published June 2026 pricing: Muster is $4,995 one-time for the Sprint (or $499/mo for the Platform), Vanta runs $7,500–$55,000/year, and Drata starts at $7,500/year. Because Muster's Sprint is one-time and the others are annual, the two-year cost favors Muster heavily. One caveat that applies to every vendor: the C3PAO certification assessment is a separate fee, paid to the assessor, on top of whatever you spend getting ready.
Are Vanta and Drata better if my IT is cloud-native?
Often, yes — and that is the honest dividing line. Both are integration-based: you connect your cloud and identity providers (think AWS, Azure, Okta) and they monitor controls continuously. If you live in that stack, that is powerful. Muster takes the opposite approach on purpose: it never connects to your systems and never ingests CUI — you describe your environment in plain English and nothing controlled leaves your browser. That fits the many defense shops still running on-prem Active Directory and a VPN.
Does any of these certify me?
No. None of these tools — Muster, Vanta, or Drata — certify you. CMMC Level 2 certification comes from an assessment by an authorized C3PAO. What these tools do is get you ready: score your posture, organize evidence, and draft documentation. The assessor decides; the attestation is yours.
