CUI enclaves, NIST SP 800-171, SSP and POA&M, ITAR-aware design, and CMMC readiness for tier 2 and tier 3 suppliers across the DFW defense corridor and Greater Houston

Defense Contractor IT Support Built for Texas Suppliers

Texas defense suppliers are not primes. A tier 2 machine shop near the McKinney and RTX corridor, an engineering firm in the Fort Worth aerospace cluster, or an electronics manufacturer feeding Houston-area programs still has to protect controlled unclassified information under the same NIST SP 800-171 requirements a much larger company faces, usually with no compliance department to absorb the work. LayerLogix delivers managed IT and cybersecurity built for that reality: scoping CUI into an enclave so the whole company does not land in assessment scope, implementing the NIST SP 800-171 control families in a way a shop floor can actually live with, keeping the System Security Plan and POA&M current instead of stale, separating OT from IT, and putting privileged access management around the accounts attackers want most. DFARS 252.204-7012 did not go away when the CMMC Phase 2 transition was suspended in July 2026, and primes are still sending flow-down language and supplier security questionnaires. With 20+ Years Experience and 100% Texas-Based Support, we help you answer them with evidence instead of adjectives.

What We Offer

Comprehensive solutions tailored for Houston-area businesses

Scope CUI Before You Secure It

Assessment scope follows the data, not the org chart. We map where controlled unclassified information enters your business - prime portals, email attachments, drawing packages, purchase orders - who touches it, and where it comes to rest. Then we draw the smallest defensible boundary around it. Getting this right is the difference between hardening one enclave and rebuilding every system in the company.

Enclave Design for Small Suppliers

A dedicated tenant, a virtual desktop environment, or a segmented engineering share can hold CUI while quoting, HR, marketing, and general email stay outside the boundary. We build the enclave, control the doors in and out, and document it so an assessor can follow the same logic you did. You get real protection without paying to secure systems that never see a drawing.

NIST SP 800-171 Control Families in Practice

Fourteen control families and 110 requirements, and most lost points sit in the same places: access control, audit and accountability, configuration management, identification and authentication, and incident response. We implement them against Rev 2 and the June 2018 SP 800-171A, the versions CMMC Level 2 is still assessed against, and we write down exactly how each one works in your environment.

SSP and POA&M as Living Documents

A System Security Plan written once and filed away fails on contact with an assessor. We keep the SSP describing the system you actually run, keep the POA&M honest about what is open with real owners and dates, and keep your SPRS score traceable to evidence. When a prime or a government customer asks for the current version, it is current.

ITAR and Export-Controlled Data

CUI is unclassified, and GCC High is not universally mandatory. What genuinely forces it is ITAR or other export-controlled technical data, where the rules restrict who may access the information, including support personnel, and where the data physically lives. We identify which contracts carry export-controlled data, then build the tenant and access model that fits, without buying a sovereign cloud you do not need.

Flow-Down Clauses and Vendor Questionnaires

DFARS 252.204-7012 flows safeguarding and cyber incident reporting requirements down to subcontractors handling covered defense information, and the CMMC clause 252.204-7021 carries its own flowdown at paragraph (f). We help you build the supplier list, add the right purchase order language, and answer the security questionnaires primes send with consistent, evidence-backed responses instead of a different story every quarter.

OT/IT Separation and Privileged Access Management

CNC controllers, CMMs, and legacy CAM workstations often cannot take an agent and cannot be patched on your schedule. We separate the production network from the business network, control what crosses the boundary, and put vendor remote access behind privileged access management with time-limited, recorded sessions. Automated monitoring watches both sides 24/7 so a quiet lateral move does not become a production outage.

Why Choose LayerLogix?

Serving businesses throughout the Greater Houston area including McKinney, Fort Worth, Dallas, Plano, Houston, The Woodlands, Clear Lake, Austin.

A Smaller Assessment Footprint

Scoping CUI into an enclave keeps quoting, HR, and general business systems outside the boundary. Fewer systems in scope means fewer controls to implement, less evidence to maintain, and a shorter, less expensive path to a self-assessment you can defend.

Answers Primes Accept

When a flow-down clause or a supplier security questionnaire arrives, you answer from a current SSP, a real POA&M, and a score traceable to evidence. Consistent answers keep you on the bid list instead of stuck in supplier review.

Production Keeps Running

Separating OT from IT and putting vendor access behind privileged access management protects drawings and CUI without touching the machine controllers your delivery schedule depends on. Security work stops being a reason to stop the line.

No Wasted Compliance Spend

CUI is unclassified. There is no SCIF, no TEMPEST shielding, no GSA container, and no NSA-listed shredder in the requirement, and you may not need GCC High at all. Budget goes to the controls that actually score, not to classified-world hardware nobody asked you to buy.

100% Texas-Based Support

20+ Years Experience, offices in The Woodlands and Round Rock, and people who know both the DFW defense corridor and the Greater Houston supply base. Business-hours support plus after-hours emergency response, with automated monitoring running around the clock.

Our Process

1
Contract and Data Discovery - We review your active contracts and the DFARS clauses inside them to establish what covered defense information and CUI you actually receive, and from which primes or government customers.
2
CUI Data Flow Mapping - We trace where controlled unclassified information arrives, who handles it, which applications touch it, and where it comes to rest, including the shared drives and personal folders nobody documented.
3
Boundary and Enclave Design - We draw the smallest defensible assessment boundary the work allows, then design the enclave, tenant, or segmented environment that will hold CUI and keep the rest of the business out of scope.
4
Gap Assessment Against NIST SP 800-171 Rev 2 - We assess all 110 requirements using SP 800-171A from June 2018, the version CMMC Level 2 is still measured against, and produce a scored, evidence-linked gap list.
5
Remediation Roadmap and POA&M - We sequence fixes by score impact and operational risk, assign owners and realistic dates, and stand up the POA&M as a document that gets updated rather than archived.
6
Enclave Build and Migration - We deploy the environment, move CUI into it, retire the shadow copies scattered across the network, and configure access control, MFA, logging, and encryption to match what the SSP claims.
7
OT/IT Segmentation - We separate the production network from the business network, restrict what crosses the boundary, and place vendor remote access behind privileged access management with recorded, time-limited sessions.
8
SSP Authoring and Score Submission Support - We write the System Security Plan against the system you actually run, tie each requirement to evidence, and support your self-assessment score submission in SPRS.
9
Ongoing Evidence and Readiness - Automated monitoring runs 24/7, we collect audit evidence as it is generated, refresh the SSP and POA&M as the environment changes, and keep you ready if the CMMC transition restarts.

Frequently Asked Questions

The CMMC Phase 2 transition was suspended. Can we stop working on CMMC?▼
No. On 13 July 2026 the Department of War suspended the CMMC Phase 2 transition. During the suspension a requiring activity may designate only Level 1 (Self) or Level 2 (Self) on a solicitation, may not designate Level 2 (C3PAO) or Level 3 (DIBCAC), and no waivers are granted. That is an executive decision rather than a rule change, so it can restart without new rulemaking. Meanwhile DFARS 252.204-7012 is untouched and your NIST SP 800-171 obligations still apply. The practical move is to keep implementing controls and keep your self-assessment honest.
Does our whole company have to be in assessment scope, or can we build an enclave?▼
Usually an enclave works. Scope follows CUI, so if controlled unclassified information stays inside a defined boundary - a separate tenant, a virtual desktop environment, or a segmented engineering and file share - the rest of the company can stay out of scope. For a tier 2 or tier 3 shop that means quoting, HR, marketing, and general email do not have to be rebuilt. We start by mapping where CUI actually arrives, who touches it, and where it lands, then draw the boundary as tightly as the contract work allows and document it in the SSP.
Do we need Microsoft GCC High?▼
Not automatically. CUI is unclassified information, and Microsoft 365 Commercial, configured correctly, can meet DFARS and NIST SP 800-171 requirements for many suppliers. What genuinely forces GCC High is ITAR or other export-controlled technical data, because those rules restrict who may access the data, including support personnel, and where it is stored. We look at the actual data types in your contracts before recommending a tenant. Moving to GCC High when you do not need it adds licensing cost and feature gaps for no compliance benefit.
Should we upgrade our program to NIST SP 800-171 Rev 3?▼
Be careful here. CMMC Level 2 is assessed against NIST SP 800-171 Rev 2 and the June 2018 SP 800-171A. NIST withdrew both on 14 May 2024, but they remain binding through fixed-date incorporation by reference. A contractor who upgrades to Rev 3 can fail on requirements that Rev 3 dropped or reworded, because the assessment still asks the Rev 2 questions. We build the SSP and the evidence set against Rev 2 and 800-171A, and track Rev 3 separately so a future change becomes a mapping exercise instead of a rebuild.
What do the flow-down clauses actually require us to pass to our suppliers?▼
DFARS 252.204-7012 requires you to flow the safeguarding and cyber incident reporting requirements down to subcontractors when the work involves covered defense information. The CMMC clause, DFARS 252.204-7021, carries its own flowdown at paragraph (f) - and in the November 2025 clause there is no paragraph (g), which is worth knowing when a prime cites one. In practice you need a supplier list, a record of what each supplier handles, and the right language in your purchase orders. We help you build that list and respond to the questionnaires primes send.
Do we need a SCIF or special destruction equipment to handle CUI?▼
No. CUI is unclassified. There is no requirement for a SCIF, TEMPEST shielding, a GSA-approved container, or an NSA-listed shredder to handle it. What NIST SP 800-171 asks for is proportionate physical protection: controlled areas, escorted visitors, locked storage for media, and destruction that renders the information unreadable. Suppliers regularly spend real money on classified-world controls nobody asked them to buy. We keep physical security proportionate and documented, and redirect budget to the access control, logging, and configuration management gaps that actually cost points on your score.
How do you secure a shop floor full of machines that cannot be patched?▼
Machine controllers, CMMs, and older CAM workstations often run unsupported operating systems and are locked to a vendor support contract. We do not force agents onto them. Instead we separate the production network from the business network, control exactly what crosses that boundary, and put vendor remote access behind privileged access management with time-limited, recorded sessions. That keeps the shop floor available while removing the flat-network path an attacker would use to reach engineering drawings and CUI. It also shrinks scope, because the OT segment stops being a CUI system.
Do you provide IT and Cybersecurity for Defense Contractors in McKinney and nearby areas?▼
Yes. LayerLogix is based in the Greater Houston area and delivers it and cybersecurity for defense contractors to businesses across McKinney and the surrounding communities, including The Woodlands, Spring, Katy, Sugar Land, Conroe, Cypress, and Pearland. For most McKinney-area clients we can be on-site the same day when something needs hands-on attention, and our help desk is available during business hours, with after-hours emergency support. Call 713-571-2390 to check coverage for your specific address.
What does IT and Cybersecurity for Defense Contractors cost for a McKinney business?▼
Pricing depends on your size and what you need, so we do not publish a one-size-fits-all number — but McKinney businesses generally pay a flat, predictable monthly fee rather than surprise hourly bills. We start with a free, no-obligation assessment of your current setup, then give you a clear quote in plain English with no hidden costs. That way you know exactly what you are getting and what it costs before you commit.
