About the Firm

Built to guide the Defense Industrial Base through CMMC 2.0.

Our Mission

Quantum Shield Consulting exists to help small and mid-sized defense contractors achieve and maintain CMMC 2.0 readiness without the confusion, bloat, or runaway costs that often come with compliance work.

We believe the Defense Industrial Base is strongest when its smallest contractors can compete on a level playing field. That means clear guidance, honest pricing, and advisory services built around your actual scope — not a generic checklist sold to every client.

Every engagement is grounded in the CMMC 2.0 framework, the NIST SP 800-171 control family, and the Code of Professional Conduct required of every Registered Practitioner.

What is a Registered Practitioner?

A Registered Practitioner (RP) is an individual who has been trained and authorized by the Cyber-AB — the official CMMC Accreditation Body — to provide non-certified advisory services to organizations preparing for CMMC certification.

RPs help Organizations Seeking Certification (OSCs) understand the CMMC model, identify compliance gaps, and develop remediation strategies in advance of a formal assessment conducted by a C3PAO.

Every RP completes Cyber-AB-approved training, passes a background screen, and commits to the Cyber-AB Code of Professional Conduct — a standard of integrity and competence you can verify and rely on.

How We Work

A methodical path from uncertainty to assessment-ready.

01

Discover

We start by mapping your environment: FCI and CUI footprint, scope boundaries, enclave options, and current security posture.

02

Assess

A structured gap analysis against all 110 NIST SP 800-171 controls. You get a clear picture of what's in place, what's missing, and what matters most.

03

Remediate

Prioritized remediation planning with a focus on achievable wins. Policy drafting, SSP authoring, POA&M management, and evidence collection.

04

Prepare

Pre-assessment dry runs, documentation review, and stakeholder coaching so your team walks into the C3PAO engagement with confidence.

Why Quantum Shield

Credentials matter. So does how you work with people.

The RP designation sets a floor for competence and ethics. What you get with Quantum Shield goes further: direct access to the consultant doing your work, transparent pricing scoped to your situation, and advisory engagements built around your timeline — not ours.

We're selective about the clients we take on so that the clients we have get the attention they deserve. If CMMC 2.0 is on your roadmap, let's have a conversation.
