NIST 800-171 Implementation
Every Houston defense contractor handling Controlled Unclassified Information is on the hook for NIST 800-171 under DFARS 252.204-7012 — and prime contractors are enforcing it harder every quarter.
What this covers
LayerLogix delivers complete NIST 800-171 implementation: gap assessment against all 110 controls, CUI enclave architecture to minimize scope, System Security Plan development, technical control implementation across 14 families, POA&M tracking, and SPRS score submission support.
We build your 800-171 program on a foundation that scales directly into CMMC Level 2 certification.
NIST SP 800-171 · DFARS 252.204-7012
From 110 requirements to a plan that keeps up
Six cards, one living plan. Here's how we turn a list of requirements into controls your team uses, gaps with owners and dates, and evidence that's ready when a prime asks. Tap a lens, or let it play.
Where it starts · The plan on the shelf
An SSP on a shelf drifts. A living one keeps up.
A System Security Plan written once, for one contract, and then filed starts aging the day it's done. Since then you've hired people, bought laptops, added a cloud app and changed the firewall, and none of it reached the plan. Flip between the shelf copy and one that's kept current.
What LayerLogix does
- Read your current SSP against how the office really runs today
- Record changes in the plan as they happen, not at renewal time
- Keep the SSP, POA&M and SPRS score telling the same story
Step 1 · Scoping and enclave design
Four walls around your CUI, and only your CUI
The drawings and specs a prime sends you are often CUI, and the 110 requirements apply wherever that data lands. So we give CUI one home: an enclave with its own network, sign-ins, endpoints and storage. Payroll, shipping and your website can stay outside the scope.
What LayerLogix does
- Map where CUI arrives, where it sits and who touches it
- Design an enclave with its own network, identity and storage
- Keep everyday systems outside the boundary and the scope small
Step 2 · Technical controls, in the office
What the control families look like at a real desk
A control family sounds abstract until you see it at a desk. Identification is the MFA prompt on the laptop. Media protection is the USB stick that won't mount. Audit is the log of who opened a drawing. Pick a family and watch where it lives in your office.
What LayerLogix does
- Turn on MFA, encryption and audit logging inside the enclave
- Lock down USB and removable media on machines that touch CUI
- Write the policies and run the training that go with them
Step 3 · System Security Plan
Every requirement gets a plain answer: how, who, proof
The requirement tells you what. Your SSP has to say how it's done in your shop: which tool does it, who owns it and where the proof lives. We write each entry from what we actually built, so when something changes, the right entry is easy to find and update. Flip the card.
What LayerLogix does
- Describe the boundary, the data flows and each control in place
- Name an owner and an evidence source for every entry
- Update entries when systems, people or vendors change
Step 4 · Plan of Action and Milestones
Open gaps get owners, dates and a weekly push
Not everything closes on day one, and that's workable if it's written down. Each open gap goes on the POA&M with an owner, a risk rating and a realistic date. Then we review it weekly so items keep moving instead of sitting until the next audit. A few gaps can't wait at all.
What LayerLogix does
- Rank open items by risk and set target dates you can hit
- Review progress weekly and chase anything that stalls
- Spot the gaps too critical to defer and fix those first
Step 5 · SPRS score and evidence
A score you can explain, with the proof behind it
Your SPRS self-assessment starts at the maximum of 110 and loses 1, 3 or 5 points for each requirement that isn't met. As POA&M items close, those deductions come off, the SSP gets updated and the evidence is filed. Primes check SPRS before awarding work, so the score on file should be current.
What LayerLogix does
- Calculate your score with the DoD scoring method
- Help you post it to SPRS and update it as gaps close
- Carry the same SSP and evidence into CMMC Level 2 prep

What We Offer
Comprehensive solutions tailored for Houston-area businesses
Gap Assessment Against 110 Controls
Detailed assessment of your current environment against all 110 NIST 800-171 Rev 2 security requirements across 14 control families. We produce a scored gap report, a prioritized remediation roadmap, and a self-assessment score for submission to the DoD Supplier Performance Risk System (SPRS).
System Security Plan (SSP) Development
Draft and maintain your System Security Plan — the living document that describes your system boundary, data flows, and how each of the 110 controls is implemented. DFARS 252.204-7012 and the upcoming CMMC audits both require a complete, defensible SSP.
CUI Enclave Architecture
Design a segmented Controlled Unclassified Information environment — separate network, identity boundary, endpoints, and storage — that keeps your compliance scope small and your remediation cost manageable. Protect CUI without rebuilding your entire corporate network.
Technical Control Implementation
Hands-on implementation across all 14 control families: access control, awareness and training, audit and accountability, configuration management, identification and authentication, incident response, media protection, system and communications protection, and more.
POA&M Tracking and Remediation
Build and manage your Plan of Action and Milestones — the tracking document for controls that are not yet fully implemented. We prioritize by risk, set realistic remediation dates, track progress weekly, and prevent POA&M items from stagnating until your next audit.
SPRS Score Submission Support
Calculate and document your NIST 800-171 self-assessment score using the DoD scoring methodology (maximum 110, subtract 1-5 per unimplemented control). Upload the score to SPRS, keep it current, and make sure prime contractors can verify your compliance before contract award.

Meet DFARS 252.204-7012
Every DoD contractor handling Controlled Unclassified Information is contractually obligated under DFARS 252.204-7012 to implement NIST 800-171. Non-compliance can void contracts, trigger False Claims Act exposure, and disqualify you from future DoD work.
Foundation for CMMC Level 2
NIST 800-171 is the control basis for CMMC Level 2. Every hour you invest in 800-171 compliance now accelerates your CMMC certification later. Skip the rework — build it right the first time against the same underlying controls.
Reduce Assessment Scope
Our CUI enclave approach minimizes the systems subject to NIST 800-171 controls. A smaller scope means faster implementation, lower ongoing maintenance cost, and an easier path through both self-assessments and third-party audits.
Protect Federal Information
NIST 800-171 exists because CUI — technical drawings, specifications, personnel data, research — is regularly targeted by nation-state adversaries. Real compliance protects your customers, your contracts, and the defense industrial base, not just a checkbox.
Competitive Advantage in Prime Flowdowns
Prime contractors are pushing 800-171 requirements down to subcontractors aggressively. Being demonstrably compliant — with a valid SSP, current SPRS score, and working POA&M — wins you subcontract work that non-compliant competitors cannot even bid on.
