Most security programs fail before any technology is deployed — because nobody defined what needed protected, what was in scope, or where the regulatory boundary sat. USX Cyber answers those questions first. Our engineers scope the boundary, design the architecture, build the program, and operate it 24/7 — with compliance proven continuously through the GUARDIENT® platform.
USX Cyber is an engineering-led cybersecurity firm that designs, builds, and operates complete cybersecurity programs for defense contractors, government contractors, and regulated organizations. Its services span cybersecurity program engineering, scope determination and boundary analysis, security architecture, risk assessments, compliance consulting (CMMC, NIST 800-171, NIST 800-53, SOC 2, HIPAA), a 24/7 U.S.-based Security Operations Center, and continuous compliance. The programs its engineers design are operationalized through GUARDIENT®, the company's unified security and compliance platform — so the same controls that are designed are the ones enforced, monitored, and continuously evidenced.
Buy enough software and you'll have alerts, dashboards, and invoices — but still no answer to the questions an assessor, a prime, or a board actually asks: What's in scope? Where's the boundary? Which controls live where, and who owns them? Those are engineering questions, and no license agreement answers them.
USX Cyber starts where the tools can't: discovery, scoping, boundary analysis, and architecture. Then we build and operate what we designed — with GUARDIENT® generating the compliance evidence as the program runs. One methodology. One accountable team. One truth.

The engineering-led approach
Every engagement follows the USX Cyber Delivery Framework — from first discovery session to standing 24/7 operations. The platform comes last for a reason: by then, we know exactly what it needs to do.
Discovery → Architecture → Operations → ProofWe map your contracts, systems, and data flows to establish what exists and what actually needs protected. Every downstream decision — scope, boundary, architecture — is built on this evidence, not on assumptions.
Our engineers determine what's in scope, draw the regulatory boundary, and design the security architecture — segmentation, identity, control placement — engineered to keep the assessed environment as small as your mission allows.
We build what the architecture specifies: hardened systems, enforced segmentation, deployed controls, and the governance documents — SSP, POA&M, policies — that make the program real and reviewable.
OverWatch — our U.S.-based SOC — runs the program around the clock. Analysts who know your boundary investigate every escalation and act on confirmed threats. Monitoring maps to your control set, so operations never drift from obligations.
Compliance stops being an annual project. Evidence is generated continuously from program operations, control drift surfaces the day it happens, and every assessment becomes a scheduled event instead of an emergency.
The platform that operationalizes everything above. The controls our engineers design are the controls GUARDIENT® enforces, monitors, and evidences — one system carrying the program from implementation through continuous compliance.
Anyone can sell you detection. The organizations we serve — defense contractors, critical suppliers, regulated operators — need someone accountable for the decisions underneath it: scope, boundary, architecture, governance. That's the work we're built for.
Before you spend on technology, you know what's in scope, what's out, where the boundary sits, and why — in writing, with engineering rationale an assessor can follow. Certainty is the first deliverable of every engagement.
A boundary engineered smaller means fewer assessed systems, less tooling, and a lighter audit. Clients routinely fund the entire engagement out of what deliberate scoping and tool consolidation remove from their budget.
Because operations run on GUARDIENT®, every control is enforced and evidenced continuously. When an assessor, a prime, or your board asks where you stand, the answer is current as of this morning — not last audit season.
Programs designed deliberately cost less to run, hold up under assessment, and produce compliance that never lapses — because the evidence is generated by operations, not assembled before audits.

“USX Cyber has been an outstanding partner for Corinth. As our MSSP, they keep our environment secure and give us the confidence to focus on delivering for our DoD and Civilian Federal Customers. When we needed to execute our C-SCRM plan, they led the effort and we completed it in record time. Now they’re guiding us through CMMC Level 2 certification, and based on our experience, I have no doubt they’ll get us there. They don’t just provide a service; they operate as an extension of our team.”
"From Day 1, USX Cyber delivered real value protecting our 100+ systems and critical IP. Our operations are running smoother and safer than ever."
“USX Cyber has been a real game changer for us. Their team provides fast responses to our cybersecurity issues and resolves problems quickly. Their new GUARDIENT® platform significantly reduces our workload and helps keep us CMMC compliant. This allows us to focus on our engineering work and customers.”
Trusted by leading organizations
USX Cyber is an engineering-led cybersecurity firm. We design, build, and operate complete cybersecurity programs: cybersecurity program engineering, security architecture, scope determination and boundary analysis, risk assessments, security engineering, compliance consulting, a 24/7 U.S.-based SOC, continuous monitoring, and continuous compliance. The programs our engineers design are operationalized through GUARDIENT®, our unified cybersecurity and compliance platform.
The Delivery Framework is the engineering methodology behind every engagement. It moves through eight phases:
The framework exists to reduce uncertainty before technology is deployed — then to build and operate the program those decisions define. Read the full methodology →
GUARDIENT® by USX Cyber is the operational platform that runs the programs we engineer. It unifies Extended Detection and Response (XDR), a 24/7 U.S.-based Security Operations Center (SOC), Governance Risk and Compliance (GRC) automation, and Remote Monitoring and Management (RMM) in a single system — so security operations continuously produce the evidence needed for CMMC, NIST 800-171, SOC 2, and other frameworks, rather than requiring a separate manual collection effort.
Scope determines everything downstream: which systems are assessed, which controls apply, what tooling is required, and what the program costs to operate. Boundary analysis defines where CUI actually lives and flows — which lets the assessed environment be engineered smaller through enclaves and segmentation, without disrupting the business.
Organizations that skip this engineering either over-scope (paying to protect and audit systems that never needed it) or under-scope (producing assessment findings and real exposure). Both outcomes are more expensive than doing the engineering first.
An MSSP monitors the environment you already have. A software vendor sells you tools and leaves the program design to you. USX Cyber is a cybersecurity engineering firm:
One accountable team owns the program from first survey to standing operations.
Organizations following the Delivery Framework typically reach full audit readiness in approximately 90 days, compared to the 6–12 months common with traditional approaches. Deliberate scoping and boundary engineering shrink the assessed environment up front, and GUARDIENT® continuously captures evidence from security operations mapped to CMMC and NIST 800-171 controls — removing most of the manual collection work that slows traditional audit preparation.

Stop buying tools against an undefined boundary. Stop running compliance as an annual emergency. Start with an engineering conversation — your contracts, your environment, your scope — and see what a deliberately designed program looks like.
A working session with our engineering team — we'll map your obligations, pressure-test your scope, and show you how the methodology and the GUARDIENT® platform would apply to your organization.
