grc.engineering vs Vanta for CMMC L2.

Vanta is the most recognized name in automated compliance — and for good reason. If you're running SOC 2, ISO 27001, or HIPAA for a SaaS company, Vanta is often the right answer. This page explains why CMMC L2 is a fundamentally different problem, and why a CMMC-native stack produces better outcomes for defense contractors.

Where Vanta wins

• SOC 2 and ISO 27001 automation. Vanta essentially owns the startup SOC 2 market. Integration breadth, policy templates, and auditor workflow are best-in-class for cloud-native companies.
• Brand recognition. "We use Vanta" is a credible answer in enterprise sales cycles. It signals maturity to procurement teams evaluating SaaS vendors.
• Integration breadth. 300+ integrations covering the SaaS stack most startups run — AWS, GCP, Azure, Okta, GitHub, Jira, the full list. Evidence collection is largely automatic.
• Continuous monitoring. Real-time compliance posture dashboard that surfaces configuration drift as it happens.
• Speed to audit-ready. SOC 2 Type I in as little as 4 weeks for a well-structured startup.

Where Vanta struggles for CMMC L2

The pricing reality

Vanta charges $10,000–$50,000 per year as a recurring SaaS subscription. That's the right model for continuous SOC 2 monitoring — you pay for the platform, you get continuous compliance posture. But for CMMC L2, you don't need a monitoring dashboard that runs forever. You need:

1. An assessment-ready SSP that an assessor can validate against your infrastructure
2. Evidence packages with cryptographic provenance that hold up under scrutiny
3. A detect/respond stack running inside your authorization boundary
4. POA&M automation that tracks remediation against specific control failures

That's a fixed-scope engagement, not a perpetual subscription. Our engagements range from $8,000 (CMMC L1 self-assessment) to $60,000 (full L2 C3PAO preparation with detect/respond deployment). You own the deliverables. There's no annual renewal to keep your compliance artifacts accessible.

The evidence quality gap

Vanta collects evidence via API integrations and stores it in their cloud. grc.engineering produces court-defensible evidence packages with SHA256-signed provenance chains.

The "continuous compliance" question

Vanta's core value proposition is "continuous compliance" — a real-time dashboard showing your compliance posture. That's genuinely valuable for SOC 2, where your auditor wants to see evidence of continuous controls.

But for CMMC L2, "continuous compliance" means something specific: your SSP must reflect your actual infrastructure at the time of assessment, and your evidence must be current. A dashboard showing green checkmarks is not an SSP. An assessor from a C3PAO isn't going to log into Vanta — they're going to review your System Security Plan, your evidence binders, and your POA&M.

Our approach: the SSP is rebuilt from pipeline artifacts on every commit. The evidence is always current because it's generated from infrastructure-as-code, not from periodic API snapshots. The POA&M generates itself from failed pipeline stages. That's actual continuous compliance — not a monitoring dashboard, but a build artifact that's never stale.

What this actually looks like

This is a redacted snippet from a real OSCAL component-definition — the kind of artifact our pipeline emits on every commit. Vanta does not produce OSCAL output.

        }]

    }]
  }
}

The architectural mismatch, in one paragraph

Vanta is built on the assumption that compliance evidence flows up from your infrastructure into a centralized SaaS platform. For SOC 2, that's efficient — your evidence is cloud configuration data, access logs, and policy acknowledgments. For CMMC L2, evidence includes SIEM logs, incident response artifacts, and vulnerability scan results that may touch CUI. Sending CUI-adjacent evidence to a multi-tenant SaaS platform that doesn't hold CMMC L2 authorization introduces a scoping problem — you've just expanded your authorization boundary to include Vanta. The architectural fix: keep evidence collection and storage inside your authorization boundary, and publish only assurance claims (OSCAL artifacts + cryptographic hashes). That's the primitive grc.engineering is built around.

When you'd pick us over Vanta

• Your primary compliance driver is a DoD contract, not enterprise sales
• You handle CUI and need evidence that stays inside your authorization boundary
• You need an SSP an assessor can validate, not a dashboard an assessor can't access
• You want OSCAL machine-readable artifacts, not PDF exports
• You need DFARS clause flow-down tracking and ITAR scoping
• You want a fixed-scope engagement rather than a $10K+/year recurring subscription
• You need court-defensible evidence with cryptographic provenance chains
• Your engineering team wants compliance as a CI/CD pipeline, not a separate platform login

When you'd pick Vanta over us

• Your primary compliance driver is SOC 2 or ISO 27001
• You don't handle CUI or have DoD contract obligations
• You're a SaaS company where compliance is a sales enablement function
• You prefer a platform product with a dashboard over a pipeline-and-consulting engagement
• You need broad integration coverage across 300+ SaaS tools
