CMMC readiness has become one of the most confusing and misunderstood challenges facing the Defense Industrial Base.
But most organizations aren’t struggling because they lack options. They’re struggling because the ecosystem feels fragmented. Advisors say one thing. C3PAOs say another. MSPs, legal teams, insurance carriers, and readiness firms all add their own layers of noise.
Your time and trust are the two most valuable things you can give, and any guidance should honor that by focusing on what actually moves you toward certification without fear tactics and recycled talking points.
With that in mind, we’ve distilled a field-tested roadmap from CMMC Without the Theater: What Actually Moves Your Toward Certification, an on-demand webinar between CyberSheath’s Casey Lang, SVP of Compliance, and Coalfire Federal’s Travis Goldbach, VP of Strategic Business Development (GTM), an accredited C3PAO. The goal: clarity on the rules, the traps to avoid, and the concrete steps that lead to passing a CMMC assessment.
Understanding the CMMC Final Rule
CMMC is rolling out in phases, each with distinct implications for organizations pursuing DOD contracts.
- Phase 1, which began in November 2025, allows self-attestation of full compliance. Partial scores no longer suffice, and some programs already require third-party certification even during this phase.
- Phase 2, starting in November 2026, moves many organizations to mandatory third-party Level 2 certification, and some programs may also introduce certain Level 3 requirements depending on their mission needs.
- By Phase 3, full Level 3 certification is overseen by DCMA DIBCAC—not a C3PAO—and Phase 4 embeds Level 1–3 determinations across all DOD engagements.

Regardless of phase, annual affirmations are required. As Travis notes, “There needs to be an annual affirmation at all levels affirming that you are actually meeting the requirements.”
Understanding these timelines is crucial. The window to act is now: delays can mean longer queues for assessments, higher costs, and fewer options for remediation.
The Five Traps Most Organizations Fall Into
Even experienced organizations stumble in predictable ways when preparing for a C3PAO assessment. Knowing these traps—and why they happen—makes it possible to avoid them.
1. Overspending on Tools Before Defining Scope
Many companies buy GCC High, a GRC platform, or a “full security stack” before mapping their Controlled Unclassified Information (CUI) boundary. But CMMC isn’t about the fanciest tools—it’s about proving control effectiveness within a clearly defined scope.
Travis says it best: “To be truthful, CMMC doesn’t require the best-in-class tools. It requires meeting the control objectives within the defined boundary.”
2. Weak or Incomplete Scoping
CMMC is data-centric. Organizations that fail to map how CUI is received, stored, processed, and transmitted often misdefine their assessment boundary. Teams across business development, contracts, engineering, project management, and cloud services must all be included in the analysis.
3. SSPs That Don’t Reflect Reality
The System Security Plan (SSP) must accurately describe boundaries, assets, and shared responsibilities. Generic or contradictory SSPs derail assessments because, as Travis points out, “We can’t validate controls without the documented evidence.”
4. Misreading NIST 900-171A
NIST 800‑171A expands 110 NIST 800‑171 controls into 320 assessment objectives. Every verb matters: define, identify, specify. If it isn’t documented, it isn’t enforceable. Casey notes, “NIST 800‑171A is a gift. It’s the questions auditors will ask. If your SSP is at that level of granularity, it keeps everyone on track.”
5. Waiting Too Long and Compressing Timelines
Travis warns: “If you wait until late 2026, expect longer scheduling queues, higher costs, and limited assessor availability.”
What Actually Moves the Needle for CMMC Readiness
Avoiding the traps is only half the story. Success comes from deliberate, ongoing practices that create repeatable, verifiable compliance.
- Start by mapping your CUI. Document where it lands, travels, and is stored—including endpoints, servers, and cloud services. Track who touches it and what systems transfer or access it. Clearly distinguish CUI assets from specialized assets (like OT/IoT or legacy systems that can’t be fully secured) and mitigate with compensating controls.
- Rethink POA&Ms (Plan of Action & Milestones). Not every control can be POA&M’d, and operational changes may trigger recertification. As Travis says, “POA&Ms don’t save a weak environment—they validate a strong one.”
- Institutionalize controls so they are process-driven, not dependent on a single person. Recurring activities—patching, change management, access reviews, vulnerability remediation—must be demonstrably ongoing.
- Finally, treat evidence as a daily habit. Logs, tickets, configurations, training records, and access reviews must be current, traceable, and repeatable. As Travis puts it, “If you can’t prove it, it didn’t happen.”

Navigating the CMMC Ecosystem: RPO vs. C3PAO
RPOs help organizations assess readiness and remediate gaps, while C3PAOs remain independent, assessing only what exists. This separation ensures credibility and prevents conflicts of interest. Travis explains, “We have to stay independent. We can only assess what exists, and we can’t help you fix gaps as a C3PAO.”
Choose partners with regulated-industry experience, CCP/CCA credentials, and robust quality assurance processes. Align their expertise with your sector—manufacturing, professional services, or staff augmentation—to minimize surprises during assessment.
Supply Chain Reality
Primes increasingly monitor supplier readiness. Many now require subcontractors to achieve Level 2 certification—or risk exclusion from the supply chain. Communicate progress proactively, respond promptly, and maintain a defensible plan. Travis notes, “Every prime I speak with says their number one risk is their supply chain. I’ve seen primes tell subs, ‘If you don’t get Level 2 assessed, you won’t be part of our supply chain.’”
A Practical Five-Step Path to Certification
Certification is a journey, not a single event:
1. Get in Line with a C3PAO. Early conversations matter; lead times can exceed eight weeks. Align scheduling with your remediation plan to avoid assessment mid-gap.
2. Assess Yourself. Conduct a self-assessment, then consider an RPO gap assessment or a mock assessment. “We’ve seen many organizations doing mock assessments prior to the real one—a great way to understand if you’ll meet requirements,” says Travis. Learn more about CMMC compliance assessment services.
3. Remediate Gaps. Close controls before booking your assessment. Use realistic POA&Ms where needed.
4. Operate and Maintain Compliance. Institutionalize recurring activities, keep ownership clear, and ensure evidence is up to date.
5. Certify. Package evidence, proceed through the C3PAO assessment, and maintain annual affirmation post-certification.
Each step builds on the last; skipping or compressing any stage increases risk, cost, and likelihood of surprises.
Treat CMMC as a Lifecycle
CMMC is not a one-and-done project. As Travis summarizes, “From a C3PAO perspective, CMMC is really a life cycle. The companies that understand that will move faster, spend less, and pass with far fewer surprises.” For more candid C3PAO insights, download the CMMC Level 2 Assessment Guide: What C3PAOs Expect From Defense Contractors.
