CMMC Compliance Services for California Defense Contractors

Get from gap assessment to C3PAO-ready without dismantling your operations.

Schedule a CMMC Scoping Call

CMMC compliance services help defense contractors and manufacturers meet the requirements of the Cybersecurity Maturity Model Certification program before contract awards require it. Consilien provides gap assessment, SSP and POA&M development, CUI boundary mapping, enclave design, policy and evidence architecture, and ongoing C3PAO readiness for aerospace suppliers, metal finishing shops, and tier-2 defense subcontractors across California.

Most defense suppliers in California aren't starting from zero. They have IT infrastructure, some security controls, maybe even a NIST 800-171 self-assessment somewhere in a shared folder. What they don't have is a program built to survive a C3PAO assessment. Those are two very different things.

CMMC Phase 1 enforcement began November 10, 2025. Phase 2, which brings mandatory third-party C3PAO assessments for most Level 2 contractors, starts November 2026. The Cyber-AB reports assessment backlogs of 8 to 14 weeks in high-demand regions like California. If you haven't started, you're already competing for slots.

We've spent years building CMMC programs for NADCAP-accredited metal finishing shops, tier-2 aerospace suppliers, and multi-process defense manufacturers across Los Angeles, Orange County, and the greater California defense industrial base. The work isn't generic. It's built around how these businesses actually operate.

What's Actually Blocking Most Contractors

Forget the IT checklist for a moment. The contractors who fail assessments aren't failing because they lack endpoint protection or MFA. They're failing on documentation and evidence.

Redspin's 2025 study of 180 DoD contractors found that 68% had been preparing for CMMC for over a year. The dominant reason isn't technology. It's the gap between controls that are working in practice and the documented, assessor-verifiable proof that those controls exist.

A C3PAO assessor uses three verification methods under NIST SP 800-171A: Examine, Interview, and Test. Examine means reviewing your documentation. Interview means asking your staff to explain the control in their own words. Test means demonstrating that what the documentation says is what actually happens in production.

Three ways to fail. Most contractors are exposed on all three.

For manufacturers, there's a fourth complication. CUI doesn't stay in your email server. It moves through ERP systems, customer drawing repositories, printed job travelers, machinist workstations, quality labs, and inspection bays. A CMMC program built by a generic IT consultant who's never walked a production floor will produce a System Security Plan that doesn't match your real environment. And SSP-to-practice disconnects are the single most common adverse finding in assessments.

What CMMC Level 2 Compliance Services Actually Include

CMMC Level 2 compliance services are the end-to-end process of mapping a defense contractor's information environment to the 110 security requirements in NIST SP 800-171 Revision 2, building the documentation and evidence architecture to satisfy a C3PAO assessment, and maintaining that posture over time. The program covers gap analysis, CUI scoping, system security planning, policy and procedure development, technical remediation, and ongoing evidence collection.

How We Work: Five Phases from Gap to Certified

CUI Scoping and Boundary Definition

Before anything else, we map where CUI actually lives in your business. Not where it theoretically should live. Where it actually flows through email, customer portals, ERP or MRP systems, engineering data environments, printed job travelers, and shop-floor workstations. This scoping analysis drives every decision downstream. Get it wrong and you either under-scope (and fail the assessment) or over-scope (and pay for controls you don't need).

Gap Assessment Against NIST 800-171

We walk the 110 controls against your actual environment. Not a questionnaire. A working session with your IT team and, for manufacturers, your operations and quality teams. Output is a prioritized gap list mapped to specific assessment objectives, with a clear read on where you're strong, where you're exposed, and what the remediation path looks like.

Documentation and Architecture Build

This is where most programs fall apart. We build the full policy and procedure architecture your SSP references. That includes the Information Security Policies and Standards document, incident response playbooks differentiated by incident type (data exfiltration, malware and ransomware, system compromise, denial of service, social-media attack), an Operations Security Procedures Manual covering audit log review, change management, media sanitization, personnel onboarding and offboarding, and visitor escort, and Shared Responsibility Matrices for every external service provider handling CUI on your behalf. Templates don't survive assessments. Custom-built documentation does.

Technical Remediation and Platform Architecture

We're platform-agnostic. For contractors with a narrow CUI footprint concentrated in a defined subset of users, a scoped PreVeil enclave alongside your existing Microsoft 365 commercial environment often saves six figures over a full GCC High migration and deploys in weeks instead of months. For organizations with broader CUI exposure, GCC High may be the right answer. We run the architecture analysis before we recommend the tool. We work with both platforms. We're paid by neither.

Evidence Program and C3PAO Readiness

Controls in place isn't the same as assessment-ready. We build the evidence architecture that connects every NIST 800-171A assessment objective to a dated, verifiable artifact. That includes a Master Evidence Tracker mapping all 320 assessment objectives, a weekly and monthly evidence collection cadence, hash-stamped policy documents with documented revision history, and a mock C3PAO assessment before your scheduled review. Evidence collected in a pre-assessment scramble looks different from evidence collected through normal operations. Assessors notice.

Where Manufacturers Get It Wrong

Here's a pattern we see constantly. A California aerospace supplier or metal finishing shop hires an IT vendor to handle CMMC. The IT vendor treats it as a technology project. They deploy MFA, spin up GCC High, install endpoint protection, and hand over a 40-page SSP template with the company name swapped in.

Eighteen months later, a C3PAO assessor asks a shop-floor supervisor to describe the procedure for handling a CUI-marked customer drawing when it comes off the printer. The supervisor doesn't know there's a procedure. The documentation says there is. That's a finding.

Then the assessor asks why the NADCAP chemical processing area doesn't appear in the CUI scope boundary diagram, even though customer drawings referencing controlled specifications are posted near the anodizing line. That's another finding.

CMMC scope follows CUI. In a real manufacturing operation, CUI flows through quality, production, inspection, shipping, and receiving. Not just the email server. A program that doesn't start by understanding the production floor will cost more, take longer, and perform worse when it actually counts.

We have direct experience building CMMC programs for NADCAP-accredited aerospace metal finishing suppliers, multi-process manufacturers, and tier-2 defense subcontractors. The shop-floor dimension isn't a footnote in our work. It's the starting point.

Example Scenarios from Our Work

Shop-Floor and IT Alignment

A NADCAP-accredited aerospace metal finishing supplier in California needed to integrate CMMC Level 2 into its existing AS9100D quality management system without disrupting AS9100 and NADCAP audit cadences. We extended the management review process to cover both, mapped CMMC controls to existing AS9100 procedures where they overlapped, and built a paper-aware CUI handling SOP that matched how the shop actually moved drawings. The result was a single integrated quality and information security management system.

Hybrid CUI Boundary for a Full-Scope Manufacturer

A full-scope metal finishing workshop with paper job travelers, contract workers from staffing agencies, and a NADCAP-restricted chemical processing area needed a CUI boundary that held up in both digital and physical environments. We catalogued over 40 distinct CUI handling events, built zone-based physical access controls layered onto existing chemical-safety zones, and produced a contract-worker controls module covering background screening, CUI awareness training, and staffing agency flow-down requirements under DFARS 252.204-7012(m).

PreVeil Enclave Over GCC High

A mid-sized aerospace supplier with roughly 70 employees was being pushed toward a full GCC High migration by its existing IT advisor. After scoping the actual CUI footprint, we found it was concentrated in about 10 engineering and program management staff on DoD programs. A PreVeil enclave alongside the existing commercial Microsoft 365 tenant deployed in weeks, preserved email addresses for the whole company, and avoided the disruption and licensing cost of an org-wide cloud migration.

Who This Is Right For

This engagement is built for:

  • Tier-2 defense subcontractors and prime contractors in California handling Controlled Unclassified Information on DoD contracts
  • NADCAP-accredited aerospace metal finishing, chemical processing, and special-process manufacturers with active defense work
  • Electronics manufacturers, machining shops, and engineering services firms in the Los Angeles, Orange County, Inland Empire, and San Diego defense supply chain
  • Companies with an existing IT environment and partial security controls that haven't yet built the documentation and evidence architecture a C3PAO assessment requires
  • Organizations scheduled for a C3PAO assessment in the next 6 to 18 months that need structured readiness support

This isn't the right fit if:

You're a software company or professional services firm with no physical production environment, no controlled drawings, and a digital-only CUI footprint. There are CMMC consultancies better suited to that engagement profile. Our approach is built for manufacturers and suppliers where CUI flows through physical production environments, not just an inbox.

What the Assessment Actually Tests

A C3PAO assessment isn't a questionnaire. The NIST SP 800-171A methodology verifies every applicable objective across 14 control families through three methods.

Verification Method
What It Tests
Common Failure Point
Examine
Your documentation and configuration exports
SSP doesn't reflect the actual environment
Interview
Whether your staff can explain the controls they own
Roles in policies don't match real staff
Test
Whether controls operate as documented in production
Controls exist on paper but aren't being executed

All 110 controls. 320 assessment objectives. Three ways to demonstrate each. The evidence architecture has to support all three for every applicable objective. That's the standard.

What Consilien Brings to CMMC Work

Founded in 2001 and headquartered in Torrance, Consilien has spent over two decades working with manufacturers across Los Angeles, Orange County, and the California defense supply chain. Several of our manufacturing clients have been with us for over a decade, including aerospace clients with active DoD contracts.

Our CMMC practice is built around a dedicated consultant with specific experience in NIST 800-171, CMMC Level 2 implementation, SSP and POA&M development, and manufacturer-specific CUI boundary design. The work isn't staffed to generalists.

We do the analysis that tells you what your business actually needs, and then we build the program around it.

Common Questions About CMMC Compliance Services

How long does CMMC Level 2 compliance take for a California manufacturer?
Realistically, 6 to 18 months depending on starting posture. Redspin's 2025 study found 68% of contractors had been preparing for over a year. Be skeptical of any consultant quoting weeks. The documentation and evidence work takes real time, and shortcuts produce the SSP-to-practice disconnects that fail assessments. If your starting posture includes a strong NIST 800-171 foundation and existing IT controls, the low end of that range is achievable. Starting from scratch on documentation, plan for the longer end.
What's the difference between CMMC Level 1 and Level 2?
Level 1 covers 17 foundational cybersecurity practices and applies to contractors handling Federal Contract Information that isn't CUI. It's self-assessed annually. Level 2 covers all 110 requirements from NIST SP 800-171 Rev 2 and applies to contractors handling Controlled Unclassified Information. Most Level 2 contractors will require a third-party C3PAO assessment starting in Phase 2 (November 2026). If your DoD contracts include CUI, you almost certainly need Level 2.
Do we need GCC High, or is there another option?
GCC High is the right answer for some organizations. It isn't the right answer for all of them. For manufacturers with a narrow CUI footprint concentrated in a defined subset of users, a scoped PreVeil enclave alongside existing commercial Microsoft 365 infrastructure can satisfy the FedRAMP Moderate-equivalent requirement at materially lower cost and deployment time. The answer depends on your CUI footprint analysis, not on which platform your IT vendor is most comfortable selling.
What is a System Security Plan and why does it matter?
A System Security Plan (SSP) is the foundational document that maps every NIST 800-171 control to its implementation in your specific environment. It names who is responsible, what evidence demonstrates compliance, and what supporting procedures back each control. The Greenberg Traurig October 2025 analysis of CMMC audit preparation is direct on this point: an SSP that doesn't reflect the current environment will result in a finding that an assessment couldn't be completed. The SSP isn't a form. It's the artifact the entire assessment rests on.
Can we handle CMMC internally without a consultant?
Technically, yes. Practically, the documentation work alone, covering 110 controls across 14 families with custom-authored procedures that match your actual environment, is a significant undertaking for a team that also has a business to run. Most manufacturers pursuing Level 2 certification use outside support for at least the documentation and evidence architecture phases, even if their internal IT team handles day-to-day technical remediation. The cost of a failed first assessment, plus the delay from a 14-week backlog to reschedule, is substantially higher than getting it right the first time.
What happens if there are gaps we can't close before the assessment?
The Final Rule allows for conditional certification. Gaps that aren't fully remediated by assessment date go into a Plan of Action and Milestones (POA&M) with realistic timelines. Not every open item blocks certification. Gaps in access control, CUI handling, and documentation quality are harder to carry through a POA&M than configuration gaps in lower-risk controls. We'll tell you what's survivable and what needs to be closed before the assessment date.

Don't Wait for a Contract to Force It

Phase 2 C3PAO assessments start in November 2026. Assessment slots are already booking 8 to 14 weeks out. Contractors who secure assessment dates early will be in front of the contractors still trying to finish their SSP when the deadline hits.

The contractor that starts now walks into an assessment with a complete evidence program and a year of operational cadence behind it. The one that starts six months out is generating evidence in a scramble, and assessors can tell.

If your DoD contracts include CUI and you haven't mapped your scope, built your SSP, or established your evidence collection cadence, the right time to start is today.

Not sure where you stand? Start with our CMMC gap assessment to find out exactly which controls are in place, which aren't, and what the realistic path to C3PAO readiness looks like for your specific environment.
