CMMC Compliance — Tustin, CA
The base closed. The supply chain didn’t.
MCAS Tustin closed in 1999. The defense ecosystem it seeded never left. Tustin sits at the center of Orange County’s aerospace corridor — between Irvine’s defense tech cluster and Santa Ana’s manufacturing base — with a dense concentration of engineering subcontractors, defense IT firms, aerospace component shops, and professional services handling CUI on behalf of primes across the county. Most assumed CMMC would land on the primes, not on them. Phase 2 says otherwise.
Intelecis is headquartered in Fullerton, a short drive up the 55, and guides Tustin defense tech firms, engineering subs, aerospace suppliers, and defense IT providers through CMMC compliance Tustin from gap assessment to C3PAO-ready — without disrupting operations or losing a single contract in the process.

CMMC Compliance Tustin — The Risk
A prime relationship quietly ends. That’s how it looks.
The Tustin supplier’s exposure is rarely loud. It’s an engineering SOW that simply isn’t extended. A defense electronics account that moves to a certified competitor down the 55 in Irvine. A spot on a prime’s approved supplier list that disappears without a notice. Your prime can already view your SPRS score in the portal — and if it’s wrong, missing, or undefended, you’re at a disadvantage before the next renewal.
The DFARS CMMC Final Rule took effect November 10, 2025. Phase 1 is live. Phase 2 in November 2026 reaches existing option periods and recurring purchase orders that Tustin engineering firms and defense tech suppliers live on — not just brand-new awards. And the DOJ’s Civil Cyber-Fraud Initiative is actively pursuing False Claims Act cases against contractors whose SPRS scores aren’t backed by defensible documentation.
Could you defend your SPRS score to your prime’s compliance team today?
DFARS 252.204-7019 requires a current, documented self-assessment on file.
If your prime dropped you from their approved supplier list tomorrow, would you know why?
Primes are required to flow CMMC requirements down — and aren’t required to explain removals.
Could your team report a CUI breach to the DoD within 72 hours — tonight?
DFARS 252.204-7012 requires rapid incident reporting. Most Tustin suppliers have no plan.
Most suppliers call us after the bad news.
An SOW that didn’t renew. A spot on the prime’s approved supplier list that disappeared without warning. The work moved to a certified competitor — sometimes down the 55, sometimes just across the Tustin Legacy campus. The suppliers who call first don’t get the bad news — they get ahead of it, certify quietly, and keep the contracts that built their business.
How It Works
From exposed to certified.
Three phases. One OC-based consultant. No handoffs to offshore teams or junior staff. The same expert manages your program from kickoff through certification and every renewal after — built around how Tustin defense tech firms, engineering subs, aerospace suppliers, and IT providers actually operate.
Gap Assessment & SPRS Scoring
We evaluate your entire Tustin environment against all 110 NIST 800-171 controls — engineering workstations, production and test areas, server rooms, field laptops, shared mailboxes, and prime-portal access — calculate your accurate SPRS score, and document every gap. We develop your System Security Plan (SSP) and Plan of Action & Milestones (POA&M) in plain language and guide you through submitting your score to the SPRS portal with defensible supporting documentation.
Remediation & Control Implementation
We help implement the controls needed to close every gap — access management, MFA, endpoint protection, audit logging, incident response planning, policy documentation, and staff training across your engineering, production, and back-office operations. A gap report you have to act on yourself isn’t compliance — it’s homework. We do the work alongside your team so your C3PAO assessor finds nothing outstanding.
Certification & Ongoing Protection
We prepare full evidence packages, run mock assessments, and walk your team through the C3PAO audit. One certification covers every prime relationship and federal customer you serve. After certification we monitor your posture continuously — so annual affirmations and triennial renewals never catch you off guard, and your recurring SOWs and POs never quietly stop renewing.

The Three Levels
Getting the wrong level costs you the contract.
Certification at the wrong level means your certification doesn’t satisfy your contract requirements — even after all the work is done. Most Tustin defense tech firms, engineering subcontractors, aerospace suppliers, and defense IT providers fall under Level 2.
Foundational
1
Basic Cyber Hygiene
For subcontractors handling Federal Contract Information without access to CUI. Annual self-attestation — no third-party auditor required.
- Based on FAR 52.204-21
- Annual company affirmation
- No C3PAO assessment required
Most Common in Tustin
2
Advanced Cyber Hygiene
For contractors handling Controlled Unclassified Information. If an OC prime passes you program drawings, specifications, technical data, or engineering deliverables, this is almost certainly your level — and it applies to the majority of Tustin defense tech firms and engineering suppliers.
- Mandatory C3PAO third-party assessment
- Annual affirmation between cycles
- Aligned to NIST SP 800-171
- 3-year certification cycle

CMMC Tustin — By the Numbers
Tustin sits at the middle of Orange County’s aerospace corridor — between Irvine and Santa Ana, feeding primes across the county.
Defense tech firms in the Tustin Legacy business park. Engineering subs along the Irvine-Tustin corridor. Aerospace component suppliers in North Tustin. Defense IT providers and professional services handling CUI in Old Town. Every one of them is inside the OC defense supply chain — and CMMC reaches all of them.

Why Intelecis
Built around security. Not bolted onto it.
Most IT companies added CMMC to their service menu when contracts started requiring it. Intelecis built its practice around advanced cybersecurity — including classified military and intelligence environments — long before CMMC existed. We’re based in Fullerton, a short drive up the 55, and we work with Tustin defense tech firms, engineering subcontractors, aerospace suppliers, and defense IT providers every week.
Military Security Foundation
Our team brings classified military intelligence experience to every engagement. NSA-accredited for Cyber Incident Response Assistance — one of the only firms in Southern California that can make that claim. This isn’t a marketing credential. It’s the difference between compliance on paper and compliance that holds up.
We Help Close Gaps — Not Just Name Them
A gap report you have to act on yourself isn’t compliance — it’s homework that sits on someone’s desk. Intelecis helps implement every missing control, policy, and documentation requirement alongside your team. When your C3PAO assessor arrives, there’s nothing left to find.
One Consultant, Start to Finish
No ticketing systems. No rotating junior staff. No explaining yourself to someone new every month. A dedicated Intelecis consultant manages your compliance program from kickoff through certification and every renewal after — the same expert, the same relationship, throughout.
Full Documentation — Walk In Ready
SSPs, POA&Ms, policies, and evidence packages — all built and maintained by Intelecis. You walk into assessment day with every document organized, current, and defensible. Not scrambling to find the right file the night before.
Compliance That Doesn’t Expire
CMMC requires annual affirmations and triennial re-assessments. Most firms pass certification and then drift. Intelecis monitors your posture continuously — so your certification and your contracts never quietly expire while you’re focused on running the business.

Who It Applies To — Tustin
If an OC prime passes CUI to you, this is you.
CMMC requirements flow through every tier of the Orange County defense supply chain — including small Tustin subcontractors that never see a direct DoD contract. If a prime passes CUI to you, you’re in scope.
🖥️
Defense Technology Firms

Without CMMC: tier separation doesn’t protect you once CUI is in your inbox or on your network.
Common Questions
Answered plainly.
No acronym soup. No compliance theatre. Direct answers to what Tustin defense tech firms, engineering subs, and aerospace suppliers actually ask — and what it means for your business.
We're a subcontractor to an OC prime, not a direct DoD contractor. Doesn't our prime's CMMC certification cover us?
No — and this is the single most expensive misconception in the OC subcontractor community. CMMC is environment-specific. Your prime’s certification covers your prime’s systems, not yours. The moment a prime passes you CUI under DFARS 252.204-7012, you become independently responsible for protecting it under the same 110 controls. Primes are required to flow CMMC requirements down to their subs — and to verify those subs hold the certification. The smaller the sub, the more often this gets discovered too late.
We're a defense tech firm at Tustin Legacy. Do the software platforms we build fall into scope?
If your platform stores, processes, or transmits CUI on behalf of a defense client, yes — and that’s exactly where most Tustin defense tech firms find themselves. The platform environment itself is inside the CUI boundary, which means it’s expected to meet CMMC controls end-to-end. That has implications for hosting choice (typically a FedRAMP Moderate-equivalent baseline), access management, encryption, and logging. Your free account review maps exactly which parts of your platform are in scope and what each part needs.
How long does Level 2 certification take for a Tustin firm?
For most Tustin firms, 4–9 months from gap assessment to C3PAO certification. Small engineering firms and well-managed defense tech companies often land under 5 months. Aerospace suppliers and light manufacturers with mixed commercial and defense production typically need 5–7 months because the CUI boundary crosses engineering workstations, shared drives, quality documentation, and prime portals that have never been formally inventoried. Your free account review gives you a timeline specific to your operation.
We're a defense IT / MSP serving multiple OC defense clients. How does CMMC apply to us?
If any of your clients are defense contractors who handle CUI, you’re an External Service Provider (ESP) under CMMC — and your environment is in scope wherever you touch client CUI. Your clients are required to use ESPs whose CMMC posture matches the level their own contracts require, typically Level 2. The good news: one Intelecis-led certification gives you a credential you can offer across your entire defense client portfolio. The bad news: defense clients are increasingly required to move uncertified MSPs out of the picture entirely.
Can we actually lose contracts we've held for years?
Yes — and it usually happens quietly. You don’t get a formal notice. The SOW just doesn’t extend. The purchase order stops arriving. You’re removed from the prime’s approved supplier or vendor list without an announcement. By the time you know, the work has moved to a certified competitor — often just down the 55 in Irvine or over in Costa Mesa. CMMC is a go/no-go condition now, and Phase 2 in November 2026 reaches existing option periods, not just new awards. Long-standing relationships aren’t immune.
What is the False Claims Act risk our owner keeps mentioning?
Under the DOJ’s Civil Cyber-Fraud Initiative, contractors who submit an inaccurate SPRS score can be prosecuted under the False Claims Act, which carries treble damages — 3× the contract value — plus per-claim penalties. This isn’t theoretical. The DOJ has already settled multiple cases. The exposure attaches personally to the executive who signs the attestation, not just to the company. For Tustin suppliers, that’s usually an owner-operator, president, or VP. A score that isn’t based on a defensible, documented assessment puts that person’s name on the line — not just the firm’s reputation.
