grc.engineering vs CyberSheath for CMMC L2.

CyberSheath is one of the largest managed CMMC compliance providers in the defense industrial base — and for companies with zero security staff and an imminent contract deadline, their fully-managed model can be exactly the right answer. This page explains where that model costs you more than it should, where it creates long-term dependency, and where a compliance-as-code approach produces better outcomes for contractors that want to build rather than rent.

Where CyberSheath wins

• End-to-end managed service. CyberSheath handles the enclave build, SIEM deployment, compliance tooling, and ongoing management. If your company has no security staff and needs someone to own the entire compliance program, this is a genuine differentiator — not just marketing copy.
• DIB specialization. Unlike generalist GRC platforms that bolt CMMC onto a SOC 2 engine, CyberSheath focuses exclusively on defense contractors. Their team understands DFARS clause flow-down, CUI scoping, and CMMC assessment workflows in practice.
• C3PAO partnership. CyberSheath partnered with ControlCase in January 2026 to provide CMMC Level 2 C3PAO assessments directly. That integration between the MSP building your compliance program and the assessor validating it can meaningfully reduce friction at assessment time.
• Managed enclave. They stand up and operate the Microsoft GCC High or equivalent enclave on your behalf. For a 20-person defense contractor that doesn't have an infrastructure team, this is real operational lift they're absorbing.
• Predictable scope creep containment. Fixed managed services mean you're not getting surprised by "that's out of scope" mid-engagement. The bundle is the bundle.

Where CyberSheath struggles for long-term program ownership

The pricing reality

CyberSheath's managed compliance model runs approximately $3,000–5,000 per month — $36,000–60,000 per year, every year, for as long as you hold a DoD contract that requires CMMC L2. Over a five-year contract lifecycle, that's $180,000–300,000 in compliance operating expenditure, with nothing owned at the end. If the contract doesn't renew, you walk away with a compliance posture that lives in someone else's platform.

Our engagements run $8,000 (CMMC L1 self-assessment) to $60,000 (full L2 C3PAO preparation with detect/respond deployment). After the engagement, you own the OSCAL SSP, the evidence pipeline, and the toolchain. Annual maintenance — keeping the pipeline current with CMMC program updates, re-running assessments — typically runs $8,000–15,000/year. The break-even against CyberSheath's managed model is usually inside 18 months.

The ownership gap

With a managed MSP model, your SSP and evidence live in the vendor's platform. With evidence-as-code, every artifact is in your git history — you own it unconditionally.

The managed-compliance dependency trap

The fundamental issue with fully-managed compliance is that your CMMC posture becomes a function of your MSP's operational health, not your own program. If CyberSheath has a service disruption, a staff turnover on your account, or a pricing renegotiation at contract renewal, your compliance program is directly affected. You don't own the runbooks, you don't own the evidence pipeline, and you don't have the institutional knowledge to operate the program independently.

This matters most when you actually need it to matter — at assessment time. A C3PAO assessor isn't evaluating CyberSheath; they're evaluating your security program. If your team can't explain how your access controls work, can't trace evidence to specific infrastructure configurations, and can't walk through your POA&M items without calling the MSP, that's a risk signal. CMMC L2 assessors are trained to detect compliance-as-theater.

Our approach is the opposite: we build the compliance capability inside your organization. Your team understands the pipeline because they run it. Your evidence is in your git repo because your CI/CD built it. Your assessor interview is a technical conversation your team can lead without a vendor on the call.

The C3PAO assessment reality

CyberSheath's ControlCase partnership is a genuine convenience — one vendor managing your compliance program and the assessor validating it reduces coordination overhead. But it also introduces a subtle conflict of interest worth understanding: the same organization that built your compliance program has a financial interest in declaring you assessment-ready. C3PAOs operate under CMMC-AB oversight and have obligations to assess objectively, and ControlCase has a solid reputation. But the structural dynamic is different from an independent assessment.

Our approach separates the roles: we build your compliance program and evidence pipeline; you engage an independent C3PAO of your choice for assessment. That independence typically reads better to DoD contracting officers who scrutinize CMMC assessment provenance.

When you'd pick us over CyberSheath

• You want to build internal compliance capability, not rent it indefinitely
• Your contract lifecycle is 18+ months and the lifetime cost of managed compliance adds up
• You have at least one technical staff member who can own a compliance pipeline
• You need OSCAL machine-readable SSP artifacts your team can actually read and modify
• You want transparent, published pricing rather than a custom quote with annual renegotiation risk
• You need evidence with cryptographic provenance your assessor can independently verify
• You want to understand your SPRS score and control posture, not just receive a dashboard number
• You want the freedom to switch C3PAOs or assessors without rebuilding your compliance program

When you'd pick CyberSheath over us

• You have zero security staff and no capacity to operate a compliance pipeline internally
• You need someone to own the enclave build and managed SIEM operations, not just the documentation
• Your primary concern is minimizing internal time investment, not minimizing cost
• You have an imminent contract deadline and need a fully-managed path to C3PAO assessment as fast as possible
• The ControlCase integrated assessment track is a material advantage for your timeline
