CMMC and Golden Dome: How Contractors Can Win

The Golden Dome initiative represents an unprecedented evolution in how the U.S. approaches homeland defense. Structured as a large, multi-award, program-of-programs, Golden Dome integrates all domains and capabilities under a unified command and control framework.

This program brings together some of the most advanced and battle-proven defense platforms in the U.S. arsenal, creating significant opportunities for defense contractors across space, sea, land, and cyber domains.

Though much of the attention has focused on the technical features of this effort, one requirement cuts across every discipline involved: CMMC (Cybersecurity Maturity Model Certification).

One thing is for certain: CMMC is a major component.

Why CMMC Matters for Golden Dome Programs

Data Scope. Because Golden Dome work likely involves Federal Contract Information (FCI) and Controlled Unclassified Information (CUI), CMMC will be a major aspect. The DoW may require a specific CMMC level in the solicitation; when included, meeting that level (and SPRS/affirmation mechanics) is a condition of award and performance.

In most Golden Dome task orders, that requirement is expected to be CMMC Level 2, with higher levels applied only to a limited number of high-criticality efforts.

Flow Down. One of the most important aspects of the final rule is its emphasis on flow-down, which requires prime contractors to ensure that subcontractors, suppliers, and external service providers maintain the correct CMMC level.

Early Signals. We've previously shared how major Defense contractors, such as Lockheed  Martin, Boeing, and Northrop Grumman have already made CMMC a requirement throughout their supplier network. Lacking CMMC status at the required level will prevent award, even for otherwise technically qualified bidders.

What Primes Should Be Doing Now

Prime contractors pursuing Golden Dome opportunities should integrate CMMC into early program planning by:

• Verify CMMC and SPRS status before subcontract award

• Embed cybersecurity requirements into teaming agreements and statements of work

• Consider an enclave solution to limit CUI exposure

• Ensure third-party service providers have documented security responsibilities

'Go-Anywhere' Readiness in 5 Steps

1. Aim for Level 2 (C3PAO) by default

   • If any CUI is likely, plan and budget for L2 certification (not just self).

   • This keeps you eligible when solicitations or primes require a C3PAO.

2. Shrink the scope to certify faster

   • Put CUI in a dedicated CMMC enclave.

   • Consider pulling subs into your CMMC enclave

   • Document a simple boundary + data-flow, including all ESPs, smaller scope = quicker certification.

3. Build the assessor-ready core

   • Current SSP, actionable POA&M, and an organized evidence pack mapped to 800-171.

   • Knock out quick wins (MFA, full EDR, backups, logging) before scheduling the C3PAO.

4. Lock in status & cadence

   • Post required SPRS entry and keep the annual affirmation current.

   • Use an internal/mock assessment to catch gaps before the C3PAO arrives.

5. Align your team to certification

   • Any sub touching CUI should target L2 (C3PAO) when prime/RFP requires it.

   • Capture each sub/ESP’s level and SPRS status in your bid file.
