CMMC compliance for tier 1 subcontractors
CMMC Compliance for Tier 1 Subcontractors
Tier 1 defense subs carry prime obligations without prime-scale resources. We deliver CMMC Level 2 readiness and flow-down governance for your Tier 2/3 suppliers.

Tier 1 defense subcontractors sit directly below the primes. You receive programs from Lockheed, Boeing, Northrop, Raytheon, and General Dynamics and turn around and flow that work to Tier 2 and Tier 3 suppliers. Every CUI artifact that touches your environment is flow-down under DFARS 252.204-7012 and is in scope for CMMC Level 2.
Tier 1 subs also inherit flow-down obligations. DFARS 252.204-7021 requires you to flow CMMC requirements to every sub you contract with. That means you need not only your own readiness program but a supplier assurance process capable of tracking dozens or hundreds of downstream subs.
The resource gap is the real problem. Tier 1 subs typically run on leaner IT and security teams than primes, while facing the same technical requirements.
We build CMMC programs for Tier 1 subs that achieve Level 2 readiness at Tier 1 scale and add the flow-down governance you need to manage your downstream supply chain.

Tier 1 Subcontractors: CMMC questions
When do Tier 1 subs need CMMC?
Primes are flowing Level 2 down on new contracts now.
What level do we need?
Level 2 in nearly all cases.
How do we manage downstream flow-down?
We deploy supplier scorecarding and SPRS tracking to manage DFARS 7021 obligations.
How long does readiness take?
Eight to twelve months for most Tier 1 subs.
Do we need separate enclaves per program?
Not necessarily; one enclave with program-level access controls is usually sufficient.
