Cybersecurity Maturity Model Certification (CMMC) Readiness & Implementation

Protect Your Contracts. Prepare With Confidence.

CMMC is no longer a future requirement — it’s a present-day necessity for doing business with the Department of Defense. At GSec LLC, we help contractors and subcontractors cut through the confusion and get compliance-ready without wasting time, money, or sanity.

We specialize in working with small and mid-sized businesses that don’t have in-house compliance teams. Whether you’re just starting to document your security practices or fine-tuning your environment for assessment, we bring deep experience, practical insight, and proven strategies tailored to your size, scope, and systems.

Led by a CMMC Certified Assessor (CCA) and backed by real-world cybersecurity expertise, GSec provides focused, flexible support that meets you where you are — and helps you get where you need to be. From policy development and gap assessments to full-blown readiness prep, we’re in your corner.

Our Phased Approach to Compliance

  • CMMC Scoping & Gap Analysis

    We begin by reviewing your contract requirements, flowdowns, and business activities to determine the appropriate CMMC level and define the correct scope of assessment. Whether your organization handles FCI, CUI, or both, we clarify which systems, users, and assets fall within scope — and why. Once your compliance boundary is established, we conduct a targeted gap analysis of your current cybersecurity program. You’ll walk away with a clear picture of where your organization stands, what’s missing, and what steps are needed to achieve compliance.

  • SSP, POA&M, & Documentation Development

    A strong cybersecurity program starts with strong documentation. We help you build (or clean up) your System Security Plan (SSP) and Plan of Action & Milestones (POA&M) to align with NIST SP 800-171 requirements and meet DoD expectations for audit-ready materials. Our team develops tailored baseline policies and other key compliance documents that reflect your actual environment — not just boilerplate templates. We ensure your documentation reflects what you do, not just what sounds good on paper. You get usable, credible artifacts that demonstrate maturity, satisfy assessors, and support long-term sustainment — because good documentation shouldn’t just check a box; it should work for your business.

  • Implementation Support & Remediation Guidance

    Whether it’s fine-tuning your existing tools or standing up entirely new capabilities, we provide hands-on support tailored to your environment. From configuring MFA to rolling out endpoint protections or encryption protocols, we walk you through the practical steps — and if you need something more robust, we connect you with trusted, compliant partners who specialize in scalable, DoD-ready solutions. Our goal isn’t to overwhelm you with options; it’s to help you implement the right ones in a way that aligns with your operations, budget, and timeline.

  • Audit Preparation & Long-Term Support

    GSec LLC prepares your team for CMMC assessments through structured mock audits, detailed document reviews, and pre-assessment readiness checklists tailored to your scope and environment. We simulate the C3PAO experience so there are no surprises when it counts. Our support doesn’t end at certification. As requirements evolve and controls mature, we provide ongoing compliance support to help you sustain your program. Whether it's annual reviews, evidence collection, policy updates, or staying aligned with new DoD guidance, we remain your strategic compliance partner — long after the audit is over.

Why It Matters

CMMC isn’t just another checkbox — it’s a gatekeeper. Without it, you risk being disqualified from DoD contracts, sidelined by prime contractors, and exposed to security vulnerabilities that could jeopardize your business.

But getting ahead of compliance puts you in control. It protects your reputation, strengthens your cyber posture, and makes you a more valuable partner in the defense supply chain. Primes are prioritizing subcontractors who are already CMMC-ready; if you're not prepared, someone else will be. Your ability to win (and keep) contracts depends on your ability to secure the mission. GSec LLC is here to make sure you're ready for whatever comes next.
