CMMC Compliance
for SoCal defense contractors.
CMMC compliance services for Southern California's defense industrial base — gap assessment, SPRS scoring, SSP authorship, POA&M management, control implementation, and C3PAO coordination across CMMC 2.0 Levels 1, 2, and 3. WCC has supported SoCal's aerospace, defense, and manufacturing supply chain since 2003.
CMMC compliance — the Department of Defense's certification mandate
CMMC compliance is the Department of Defense's framework for ensuring contractors protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). Under CMMC 2.0, every DoD contractor handling FCI or CUI must demonstrate a defined level of cybersecurity maturity — verified through self-assessment, third-party assessment, or government-led audit depending on contract sensitivity. The DFARS 252.204-7021 clause is rolling out across federal solicitations through 2026 and 2027, replacing the previous self-attestation-only model.
For SoCal's defense industrial base — the aerospace primes (Boeing, Northrop Grumman, Lockheed Martin, Raytheon, SpaceX, General Atomics, Aerospace Corp), the Tier-2 and Tier-3 suppliers feeding them, and the engineering services, machine shops, electronics manufacturers, and IT vendors in their supply chains — CMMC is no longer optional. Prime contractors flow DFARS clauses down to suppliers at all tiers. Without CMMC certification at the required level, your business cannot bid on new DoD work covered by the clause. With false attestation about CMMC status, you face Civil Cyber-Fraud Initiative exposure.

End-to-end CMMC compliance program management
Every WCC CMMC engagement is scoped to your current security maturity, target level, and contract timeline. These are the six core capability areas every CMMC compliance program covers.
Gap Assessment & SPRS Scoring
Current-state assessment against all 110 NIST 800-171 controls. SPRS score calculation and submission. Prioritized remediation roadmap with cost estimates and contract-timeline-aligned milestones.
SSP Authorship
System Security Plan (SSP) authored in DoD-acceptable format. Defines the assessment boundary, identifies CUI flows, documents control implementation, and forms the central document the C3PAO assessor will review.
POA&M Management
Plan of Action and Milestones for any controls not yet fully implemented. CMMC 2.0 caps POA&Ms at 5-point and 10-point weights and limits total POA&M scope. WCC tracks remediation, evidence, and closure timelines.
Control Implementation
Hands-on implementation of technical and procedural controls — MFA, FIPS-validated encryption, network segmentation, audit logging, vulnerability management, configuration baselines, and the GCC High or Azure Government tenancy required for CUI handling.
C3PAO Coordination & Audit Prep
Pre-assessment readiness review. Evidence package preparation. C3PAO selection and engagement coordination. Direct support during the C3PAO assessment including assessor liaison and finding remediation. WCC does not act as the C3PAO — that would be a conflict of interest.
Ongoing Compliance Maintenance
Annual self-assessment refresh. Annual executive affirmation support. Continuous evidence collection. Triennial C3PAO re-assessment preparation. Often combined with vCISO services for designated cybersecurity leadership.
CMMC compliance across SoCal's defense industrial base
CMMC is required for any business handling FCI or CUI in connection with a DoD contract. That includes prime contractors, Tier-2 and Tier-3 suppliers, and the IT and engineering services firms supporting them.
Aerospace Manufacturers
Aerospace primes and tiered suppliers across SoCal — Long Beach, Huntington Beach, Hawthorne, El Segundo, Redondo Beach, Palmdale, San Diego. CMMC Level 2 is typical for suppliers handling controlled program data, drawings, technical specifications, and CUI tied to DoD aerospace contracts.
Defense Electronics & Components
RF systems, sensors, embedded systems, defense electronics, and semiconductor suppliers serving DoD prime contractors. CMMC certification is increasingly required to bid on subcontracts. Many fall under ITAR concurrent with CMMC obligations.
Machine Shops & Precision Manufacturing
Precision machining, CNC fabrication, additive manufacturing, and metal finishing shops feeding aerospace and defense primes across the Inland Empire and South Bay. CMMC Level 1 minimum, Level 2 when CUI drawings or specifications are received.
Engineering Services Firms
Mechanical, electrical, software, and systems engineering firms providing services to DoD prime contractors. Engineering services typically involve CUI by definition — technical data, design documentation, performance specifications — making CMMC Level 2 the default requirement.
IT & Cybersecurity Vendors to DoD
Cloud service providers, managed services providers, cybersecurity firms, and software vendors serving DoD customers. Cloud Service Providers handling CUI must meet FedRAMP Moderate or High plus CMMC requirements. Manufacturing MSPs often need CMMC themselves.
Universities & Research Institutions
SoCal universities with DoD-funded research — USC, UCLA, Caltech, UCSD, UCI, UCR — face CMMC obligations on contracts and grants involving CUI. Research security offices coordinate institution-wide CMMC programs. Often paired with NSPM-33 research security compliance.
CMMC compliance for SoCal defense contractor frequently asked questions
CMMC (Cybersecurity Maturity Model Certification) is the Department of Defense's framework for ensuring contractors protect Federal Contract Information (FCI) and Controlled Unclassified Information (CUI). CMMC 2.0 has three levels — Level 1 (Foundational, 17 practices, annual self-assessment), Level 2 (Advanced, 110 NIST 800-171 controls, third-party assessment for most contracts), and Level 3 (Expert, 110 plus 24 NIST 800-172 controls, government-led assessment). CMMC compliance is becoming mandatory for DoD contracts as the DFARS 252.204-7021 clause rolls out across federal solicitations through 2026 and 2027.
CMMC level requirements are set by the DoD contracting authority on each solicitation. Level 1 applies to contracts involving only FCI — basic federal contract information. Level 2 applies to contracts handling CUI — covers most defense contractors including aerospace suppliers, machine shops, engineering firms, and electronics manufacturers. Level 3 applies to contracts involving the highest-value CUI — typically prime contractors handling critical defense programs. Most SoCal defense supply chain businesses need CMMC Level 2.
CMMC certification prep typically runs 6 to 18 months depending on starting maturity. Organizations with mature NIST 800-171 implementations may need 3 to 6 months. Organizations starting from scratch typically need 12 to 18 months. The phases include gap assessment (4-6 weeks), control implementation (3-9 months), evidence collection and SSP authorship (1-3 months), and pre-assessment readiness review (4-6 weeks) before engaging a C3PAO. WCC structures CMMC compliance engagements to align with contract award timelines.
CMMC costs vary by current security maturity, organization size, and target level. Level 1 self-assessment typically costs $5,000 to $15,000 if controls are already in place. Level 2 preparation typically runs $40,000 to $250,000+ depending on remediation scope. C3PAO assessment fees typically range $50,000 to $150,000 for Level 2. Ongoing maintenance and annual affirmation costs $15,000 to $50,000 per year. Cloud infrastructure migration (Microsoft 365 GCC High, Azure Government) adds licensing costs. Small businesses can sometimes leverage SBA cybersecurity grants.
NIST 800-171 is the underlying control framework — 110 security requirements across 14 domains. CMMC is the verification mechanism — DoD's certification program that audits whether contractors actually implement NIST 800-171. CMMC Level 2 IS NIST 800-171. CMMC Level 3 adds 24 controls from NIST 800-172 for highest-risk environments. CMMC work is fundamentally NIST 800-171 implementation work, with certification rigor.
C3PAO (Certified Third-Party Assessment Organization) assessments are required for most CMMC Level 2 contracts. Some non-critical Level 2 contracts allow annual self-assessment. CMMC Level 1 always uses self-assessment. CMMC Level 3 uses government-led DIBCAC assessment (Defense Industrial Base Cybersecurity Assessment Center). The contracting authority determines assessment type per solicitation. WCC coordinates the C3PAO engagement, prepares evidence packages, supports the assessment process, and manages remediation of any findings — but does not act as the C3PAO (that would be a conflict of interest).
Without CMMC compliance at the required level, your business cannot be awarded DoD contracts subject to the DFARS 252.204-7021 clause. Existing contracts remain enforceable, but contract options, modifications, and renewals will require CMMC certification once the clause flows down. False attestation about CMMC status creates False Claims Act liability — Department of Justice has actively prosecuted cybersecurity misrepresentations through the Civil Cyber-Fraud Initiative. SoCal defense contractors face real revenue loss without compliance and real legal exposure with false attestation.
Yes. The DFARS 252.204-7021 clause flows down to subcontractors at all tiers when CUI is shared. Prime contractors are responsible for ensuring their suppliers meet the appropriate CMMC level. This means SoCal Tier-2 and Tier-3 suppliers — machine shops, electronics manufacturers, engineering services firms, IT vendors serving DoD primes like Boeing, Northrop Grumman, Lockheed Martin, Raytheon, SpaceX, and General Atomics — all face CMMC requirements. Many supplier contracts now require CMMC self-assessment scores in SPRS even before formal CMMC enforcement.
