About
About Zephon
Zephon LLC is a small, minority-owned cybersecurity firm based in McKinney, Texas. Since 2018 we have helped federal and commercial organizations solve complex identity and cybersecurity problems with small teams of experienced practitioners.
Mission
To simplify complex cybersecurity challenges and deliver lasting security outcomes through experienced practitioners.
Vision
A world where cybersecurity success is measured by outcomes, not team size, vendor names, or dollars spent.
How we operate
- Senior practitioners remain accountable for delivery.
- We tell clients plainly what is working and what is not.
- We build solutions the client can operate after the engagement.
Small, senior, accountable
Our leadership has over 25 years of experience on complex, large-scale identity and security programs. Senior practitioners deliver the work directly. There are no layers between the people who scope an engagement and the people who do it.
Frequently asked questions
Do you work with both government and private sector clients?
Yes. We work with federal agencies and prime contractors, medium and large commercial enterprises in any industry, state and local agencies, and mission-driven nonprofits. Whether it is a Zero Trust roadmap for a DoD program or continuous monitoring for a university or NGO, we tailor security to your mission, not the other way around.
What frameworks and compliance standards do you align with?
The DoD Zero Trust Reference Architecture and COA (2022), CISA Zero Trust Maturity Model 2.0, NIST 800-53 Rev 5, NIST 800-171, FedRAMP, FISMA, CMMC 2.0, and the CJIS Security Policy. We align each engagement to the standards, evidence requirements, and operational constraints that apply to the client's environment.
What industries do you specialize in?
Complex identity problems aren't limited to one industry, so neither are we. Our work spans federal civilian and defense agencies, financial services, healthcare, telecommunications, higher education, and nonprofits.
Does Zephon use AI in its cybersecurity work?
Yes, where it simplifies security rather than complicating it: adaptive access controls, anomaly detection, our AISE platform, and AI-assisted engineering. Experienced practitioners review and validate every deliverable.
Federal contracting
Zephon supports federal agencies and authorized prime contractors through acquisition-ready contract vehicles and socioeconomic programs.

How can agencies contract with Zephon?
Agencies can reach us through SeaPort NxG and MDA SHIELD, and as an SBA 8(a) firm.
Can your solutions meet federal data residency and personnel requirements?
AISE deploys into your own Azure, AWS, or GCP tenant, or as SaaS that can be hosted in AWS GovCloud (US) with access restricted to U.S. citizens. Personnel and clearance requirements are confirmed and staffed for each federal engagement.
