If you’ve already started the journey toward CMMC compliance, you know it’s not just a checkbox — it’s a commitment to securing your organization’s data, protecting your position in the defense supply chain, and future-proofing your ability to win DoD contracts.
Whether you’re preparing for a formal audit or closing the final gaps in your CMMC readiness plan, this guide will walk you through what happens next, how to choose the right support, and what sets a successful submission apart.
What Is a CMMC Readiness Assessment?
A CMMC readiness assessment is a structured evaluation that simulates what a real CMMC audit will look like. It’s not just a gap analysis. It’s a dry run that tests whether your security controls, documentation, and processes are ready for third-party validation.
Done correctly, a readiness assessment should:
Map your current implementation to all 110 NIST 800-171 controls
Verify evidence for each requirement, including configurations, policies, and screenshots
Identify which items still need remediation before engaging a C3PAO (Certified Third-Party Assessment Organization)
Think of it as your dress rehearsal. It shows you exactly where you stand, helps avoid surprises during the formal audit, and can often reduce the cost and duration of your certification process.
At Cyberleaf, we deliver readiness assessments tailored for CMMC Level 2, built specifically for SMBs and mid-market contractors that may not have full-time compliance staff or in-house security teams.
What to Expect From a Formal CMMC Audit
Once you pass your readiness phase, it’s time for the real thing. A CMMC Level 2 certification requires an independent audit from a certified C3PAO. This is a rigorous, evidence - driven process that typically takes several weeks from kickoff to completion.
You will be asked to:
Provide documentation for each control
Demonstrate technical implementations live
Show consistent evidence of enforcement and ongoing maintenance
Answer questions about your policies, training, and change management processes
Auditors will not just take your word for it. They will look for proof that your cybersecurity practices are real, repeatable, and effective.
This is where many businesses stumble. Even with the right tools in place, lack of documentation or inconsistent application can result in a failed audit. Having an experienced guide during this phase makes all the difference.
Can You DIY CMMC Compliance?
It’s possible to pursue CMMC certification without a consultant, but it’s not advisable for most organizations — especially those without prior audit experience or internal cybersecurity resources.
Here’s why:
CMMC is not just about having the right security stack. It requires deep alignment between IT, HR, legal, and leadership. You need written policies, documented roles, ongoing risk management, and the ability to show auditors that your controls are not just configured — they’re operationalized.
If you’re confident you can manage this internally, a self-managed approach may work. But if not, working with a partner like Cyberleaf helps reduce risk, accelerate progress, and ensure nothing critical slips through the cracks.
