CMMC 2.0-Aligned CUI Protection for the Defense Industrial Base
Managed CMMC 2.0 compliance, NIST 800-171 control implementation, and SPRS-ready evidence for defense contractors, DoD subcontractors, and government-adjacent organizations handling FCI or CUI — delivered across Armorstack’s four portfolios: VERITY, CORE, SENTRY, and CITADEL.

Certification Isn’t Optional — It’s the Contract Gate
For most mid-market sectors, compliance is a risk-reduction exercise. For the defense industrial base, CMMC 2.0 certification is now a literal precondition to winning or keeping a contract — DFARS 252.204-7021 makes it a solicitation requirement, not a best practice. The scope problem is that the same requirement applies whether you’re a prime with a dedicated compliance team or a five-person machine shop that received a purchase order with a CUI marking. Armorstack builds the CMMC-aligned program once and keeps it evidence-ready for whichever assessor or contracting officer asks.
Five Frameworks Every Defense Contractor Should Know
The real, named requirements DoD contracting officers and C3PAO assessors will hold you to — including where the rollout stands as of mid-2026.
CMMC 2.0 & DFARS 252.204-7021
Three certification tiers: Level 1 (17 FAR 52.204-21 controls, annual self-attestation, FCI handling), Level 2 (110 NIST SP 800-171 Rev. 2 controls, C3PAO-assessed, CUI handling), and Level 3 (all Level 2 controls plus select NIST SP 800-172 enhanced controls, government-assessed). The DFARS CMMC Acquisition Rule became effective November 10, 2025; Level 2 C3PAO assessment requirements begin phasing into solicitations November 10, 2026. Note: reporting in mid-2026 indicates DoD has suspended its discretion to designate higher CMMC levels in some solicitations while the underlying rule remains in force — confirm current requirements for any specific contract before relying on this summary.

The underlying clause requiring adequate security for Covered Defense Information and rapid (72-hour) cyber incident reporting to DoD via DIBNet. This clause has applied since 2017 and remains in effect independent of where a contractor sits in the CMMC rollout timeline.

The 110 controls across 14 families that form the technical backbone of CMMC Level 2, governing protection of CUI on non-federal systems. Your SPRS score is a self-reported or assessed measure of how completely these controls are implemented.

Where a contractor uses cloud services to store or process federal data, the Federal Risk and Authorization Management Program governs the security authorization of the cloud service provider itself. FedRAMP and CMMC are complementary, not interchangeable — a FedRAMP-authorized cloud platform doesn’t make the contractor’s own environment CMMC-compliant.

Defense contractors handling technical data related to defense articles — not just physical arms and ammunition — are subject to International Traffic in Arms Regulations administered by the State Department, including registration and personnel/facility controls independent of CMMC.

One converged model, four coordinated portfolios — each mapped directly to the standards above.
24×7 Monitoring for the CUI Boundary
Continuous detection and 72-hour-reportable incident response scoped to your CMMC assessment boundary, aligned to DFARS 252.204-7012’s rapid reporting obligation and NIST 800-171’s incident response family.
Physical Security for Cleared & CUI Spaces
Access control and surveillance for CUI-scoped work areas and cleared facilities, supporting the physical protection requirements in NIST SP 800-171’s PE control family.
SSP, POA&M & SPRS Score Management
vCISO-led System Security Plan maintenance, Plan of Action & Milestones tracking, and SPRS score improvement — coordinated with your existing C3PAO or delivered as preparation before you select one.
NIST 800-171-Ready IT Backbone
Infrastructure and endpoint management built to satisfy 800-171’s access-control, configuration-management, and system-integrity families from the ground up, minimizing the gap discovered at assessment time.
Defense Contractor Security & Compliance Questions
Is CMMC 2.0 actually required yet, or still “coming soon”?
It is live. The DFARS CMMC Acquisition Rule took effect November 10, 2025, making Level 1 or Level 2 self-assessment a contract requirement in applicable solicitations now, with Level 2 C3PAO-assessed requirements phasing in starting November 10, 2026. Reporting in mid-2026 indicates some discretionary elements of the higher-level rollout have been paused, but the underlying regulation remains in force — confirm the specific clause in your solicitation rather than assuming either “fully live” or “not yet.”
Do I need CMMC if I’m a subcontractor several tiers removed from the prime?
Yes, in most cases. DFARS 252.204-7021 flows down the supply chain, and there is no small-business exemption. If you receive FCI or CUI from anyone upstream of you, the same CMMC level applies to your environment.
How does CMMC relate to DFARS 252.204-7012?
7012 is the older, still-active clause requiring adequate security for Covered Defense Information and 72-hour DoD incident reporting. CMMC adds formal, tiered certification on top of that baseline — think of 7012 as the standing obligation and CMMC as the way DoD now verifies you’re actually meeting it.
If our cloud provider is FedRAMP-authorized, are we automatically CMMC-compliant?
No. FedRAMP authorizes the cloud service provider’s own security posture. Your organization’s implementation of the 110 NIST 800-171 controls across your own systems, users, and processes is assessed separately for CMMC. A FedRAMP-authorized platform is a good foundation, not a substitute.
What does an Armorstack CMMC Readiness Consult cover?
A structured gap assessment against the 110 NIST SP 800-171 controls, review of your current SSP and SPRS score, CUI boundary scoping, and a roadmap to C3PAO assessment readiness — delivered in coordination with your existing assessor or as preparation before you select one.
