CMMC COMPLIANCE FOR ELECTRONIC SUBASSEMBLIES

CMMC Compliance for Electronic Subassemblies

Electronic subassembly manufacturers integrate PCBAs, cables, enclosures, and displays into box-level units. Drawings, BOMs, and test procedures are routinely CUI.

Why Electronic Subassemblies Need CMMC Compliance

Electronic Subassemblies sit inside the defense industrial base and regularly receive Controlled Unclassified Information from prime contractors and the Department of Defense. Every drawing, specification, statement of work, and technical data package tied to a DoD contract is almost always marked or flow-down treated as CUI under NIST SP 800-171 and DFARS 252.204-7012.

The challenge for electronic subassembly manufacturers firms is that CUI rarely stays in one place. It moves between email, file shares, cloud collaboration tools, project management platforms, engineering workstations, and field devices. Without a defined enclave and clear handling procedures, a single unsecured laptop or USB drive can break your compliance posture and create export-control exposure.

Primes like Lockheed Martin, Boeing, Northrop Grumman, Raytheon, and General Dynamics are already flowing CMMC Level 2 requirements down in subcontracts. A electronic subassembly manufacturers firm that cannot demonstrate a current SPRS score, an SSP, and a POA&M will lose eligibility to bid. Worse, a breach of CUI data can trigger both a DFARS 7012 reporting requirement and, for export-controlled data, an ITAR violation investigation.

We specialize in CMMC for electronic subassembly manufacturers firms. We know how to scope the CUI enclave so you are not rebuilding the whole business, how to implement controls without disrupting project delivery, and how to document everything in a way that will hold up to a C3PAO assessment.

Scoping, scheduling, interview coaching for your electronic subassembly manufacturers team, and on-site support during your C3PAO assessment so you pass the first time.

Which CMMC Level Do You Need?

The CMMC level you need is dictated by the information you handle under your DoD contracts. Here is how CMMC 2.0 breaks down for electronic subassembly manufacturers.

Level 1

Foundational

  • 17 basic safeguarding practices from FAR 52.204-21
  • For contractors that handle Federal Contract Information (FCI) only
  • Annual self-assessment with senior-official affirmation in SPRS
  • No CUI in scope
Level 2 — Most Common for Electronic Subassemblies

Advanced

  • All 110 controls from NIST SP 800-171 Rev. 2
  • Required for any contractor that stores, processes, or transmits CUI
  • Third-party C3PAO assessment every three years
  • The level most electronic subassembly manufacturers will need
Level 3

Expert

  • All Level 2 controls plus selected NIST SP 800-172 enhanced requirements
  • Required for contractors on the DoD's highest-priority programs
  • Government-led DIBCAC assessment every three years
  • Applies to a narrow set of contractors

Most electronic subassembly manufacturers working defense contracts handle CUI and will need Level 2. Those handling only FCI-level work may qualify for Level 1. We will review your contracts and DFARS clauses with you at no cost to confirm.

Controlled Unclassified Information We Protect in Electronic Subassemblies

Under NIST SP 800-171 and DFARS 252.204-7012, every one of these artifacts is typically CUI when tied to a DoD contract. Each one is in scope for CMMC Level 2.

Assembly Drawings & Wiring Diagrams

Box-level assembly and interconnect drawings tied to defense systems.

Bills of Materials

Multi-level BOMs for defense subassemblies, with sources and lot controls.

Functional Test Procedures

ATP, ESS, and acceptance test procedures for defense subassemblies.

Firmware & Configuration Files

Firmware images and configuration data loaded at subassembly level.

Qualification & Environmental Test Data

MIL-STD-810, 461, and 704 environmental and EMI test reports.

Prime Contract Documents

Subcontract and PO packages citing DFARS 252.204-7012.

Our 5-Step CMMC Process for Electronic Subassemblies

1

Initial Consultation

We review your prime contracts, DFARS clauses, and the types of CUI you receive to confirm your required CMMC level and define the boundary of your CUI enclave for electronic subassembly manufacturers operations.

2

Gap Analysis

A detailed review of all 110 controls across the systems, networks, and workflows your electronic subassembly manufacturers team uses to handle defense CUI, with technical testing and staff interviews.

3

Remediation Planning

A prioritized roadmap that sequences fixes by C3PAO weighting and operational impact so we never disrupt delivery to fix a policy gap in your electronic subassembly manufacturers environment.

4

Implementation

We deploy network segmentation where needed, lock down removable media and external access, encrypt CUI repositories, enforce MFA, and author every policy your SSP requires for electronic subassembly manufacturers operations.

5

Assessment Support

Mock assessments, evidence walkthroughs, staff interview prep, and on-site support during your C3PAO assessment tailored to electronic subassembly manufacturers.

Why Telco United for Electronic Subassemblies CMMC

Electronic Subassemblies Experience

We have worked with electronic subassembly manufacturers operators across the defense supply chain. We know the systems, workflows, and data flows that carry CUI in your environment.

Fixed-Price Engagements

Scoped, capped deliverables with no open-ended hourly billing so you can commit to a CMMC budget and defend it to ownership.

ITAR & EAR Awareness

We understand that a CMMC control that accidentally exposes CUI to a foreign-person employee is also an ITAR violation. We design around both obligations simultaneously.

24/7 Managed SOC

If you need continuous monitoring to satisfy the 3.6 and 3.14 control families, we provide it in-house on US-person staff.

Quality System Alignment

Our policies align cleanly with AS9100, ISO 9001, and other quality systems so your CMMC work does not collide with your existing management system.

End-to-End Delivery

We do not stop at advice. We implement the controls, author the policies, train your electronic subassembly manufacturers team, and stand next to you through the C3PAO audit.

Electronic Subassemblies CMMC FAQ

When do electronic subassembly manufacturers companies need to be CMMC compliant?
If you hold DoD subcontracts through a prime or a higher-tier sub, CMMC requirements are being flowed down on new awards right now under Phase 1 and Phase 2 of the DoD final rule. If you plan to bid in the next 12-24 months, you should be working toward Level 2 today.
What CUI does a electronic subassembly manufacturers firm actually handle?
Almost every technical data package, drawing, specification, or work order a prime sends a electronic subassembly manufacturers firm can be CUI, including design files, specifications, and project documentation. Purchase orders that cite DFARS 252.204-7012 are a strong indicator that the work package contains CUI.
How long does CMMC certification take for a electronic subassembly manufacturers company?
Most electronic subassembly manufacturers companies with 20-100 employees need six to nine months to reach Level 2 readiness. The biggest time sinks are network segmentation, documentation, and the evidence package for CUI handling.
What CMMC level does a electronic subassembly manufacturers firm typically need?
Level 2 is standard for any electronic subassembly manufacturers firm handling CUI. Level 1 applies to firms that handle only FCI. Level 3 is rare unless you support a named DoD Priority Program.
How much does CMMC cost a electronic subassembly manufacturers company?
Most 25-100 employee firms spend $60,000-$150,000 on initial Level 2 readiness, plus ongoing managed security costs of $2,000-$6,000 per month, plus the C3PAO assessment fee. We quote fixed price so you know the number up front.
Do I have to put every workstation and user on MFA?
NIST 800-171 is risk-based. We identify which systems actually handle CUI, scope them into a defined enclave, and apply the strictest controls (MFA, FIPS encryption, audit logging) at that boundary rather than across the entire business. This approach has been consistently accepted by the C3PAO community.
