As defense contractors accelerate their preparations for CMMC Level 2, many are discovering an uncomfortable truth: achieving compliance is much harder than it looks on paper.
Even organizations with mature IT teams, best-in-class cybersecurity tools, or trusted MSPs are finding that the final stretch—producing defensible evidence for a C3PAO audit—is where they fall short.
In a recent CyberSheath webinar, Michael Bailie, Vice President of Solution Engineering, opened with a reminder many defense contractors know intuitively but often underestimate in practice: “Compliance isn’t just an IT project. It truly is a team sport.”
That observation frames one of the most urgent challenges facing today’s Defense Industrial Base: preparing for a world where real audits, evidence‑driven assessments, and continuous compliance determine DOD contract eligibility.
While many contractors are working hard toward CMMC Level 2, effort alone isn’t enough. What matters is whether the right people, processes, and technologies are working together in a unified, disciplined way.
This is where the organizations that succeed and those that struggle begin to diverge.
The New Reality: The DIB is Shifting From Self-Attestation to Third-Party Validation
The DIB is moving from a self-assessment model under DFARS 252.204-7012 and SPRS reporting toward a formal third-party validation regime under CMMC. With the finalization of the CMMC 2.0 rule and the phased integration into 48 CFR, many contractors will now be required to undergo C3PAO assessments rather than rely solely on self-attestation.
Defense contractors must now demonstrate compliance through repeatable processes, documented controls, and verifiable evidence. And that’s where most organizations discover the gap between what they believe they’re doing and what they can actually prove.
According to industry research, only 1% of defense contractors feel fully prepared for CMMC audits — down significantly from previous years. “Our fourth wave of research shows that while awareness of CMMC has never been higher, true readiness remains alarmingly low,” said Dr. David M. Schneer, CEO of Merrill Research.
Michael captures this shift clearly: “Now that there is truly an audit mechanism, organizations are taking a second look, reconsidering how they’re implementing the necessary controls to achieve and maintain compliance.”
This is the heart of the challenge. Organizations are confronting hard questions about their true readiness. CMMC isn’t about checking a box—it’s about running your operation in a way that stands up to scrutiny at any time.
The CMMC Compliance Puzzle: Three Team Functions, One Mission
The most successful defense contractors—those scoring perfect 110s—understand something essential: CMMC Level 2 cannot be owned by a single department or a single person.
Compliance requires the integrated strengths of three specialized teams that form the operational backbone of a sustainable CMMC program.
- Compliance Advisory: The governance engine that drives policies, assessment readiness, documentation, POA&Ms, and the System Security Plan (SSP). It ensures your program meets not just NIST 800‑171 requirements but the deeper NIST 800‑171A assessment objectives auditors actually use.
- Security Operations: The detection and response engine that provides central event logging, behavioral monitoring, incident response, and vulnerability management—capabilities tied to DFARS and CMMC.
- Information Technology: Serves as the primary implementation function for technical controls, executing secure configurations, identity and access management, patching, hardening, change management, and endpoint protection.
Each team holds responsibilities that map directly to NIST 800-171A assessment objectives.
This is why internal teams often struggle. Even high‑performing IT departments rarely have expertise across all three domains. And MSPs who “dabble” in CMMC lack the depth to pass an audit, let alone provide evidence for one.
The takeaway is uncompromising: if even one of these disciplines is weak, misaligned, or outsourced to a non‑compliant provider, the entire program is at risk.
Why NIST 800‑171A Determines Audit Success
Many organizations only assess themselves against the 110 NIST 800‑171 controls, unaware that C3PAO auditors also reference NIST 800-171A, which breaks down each control into 320 assessment objectives. Assessors use these objectives to verify that each control is effectively implemented.
This is the difference between believing you’re compliant and being able to prove it.
As Michael explains: “Organizations need to ensure they’re not just trying to meet the high‑level 110 controls, but all of those assessment objectives.”
This is where internal assessments often fall short. Teams evaluate controls based on “intent,” rather than verifiable implementation.
Without experience interpreting the assessment objectives—and without knowing what auditors consider “sufficient evidence”—organizations routinely overestimate their readiness.
And auditors know to look deeper: “Audits are essentially show‑me exercises, validating what you say you’re doing and looking for artifact evidence.”
Evidence—not intent—is what passes an audit. If your documentation doesn’t align with execution and if your evidence isn’t defensible, your score can suffer.
A Proven Blueprint to Achieve CMMC Level 2 Certification with a Perfect 110 Score
From the start, we’ve worked to build one of the industry’s few one-stop cybersecurity compliance service providers, going beyond assessment and software licensing to solve the whole problem.
We’re here to help defense contractors achieve and maintain full compliance with DOD requirements at the appropriate level while minimizing the pain to get there—and stay there.
Our track record speaks for itself:
- 1,000+ NIST 800-171 assessments and implementation
- Dozens of CMMC Level 2 audits completed
- Zero deficiencies
- Every audit scored a perfect 110
A major differentiator is the structure of the team behind the CMMC program: Compliance, Security, and IT working as a unified extension of the client’s organization. This structure eliminates the friction and fragmentation common among MSPs.
As Michael explains:
“Our audit and certification support is us sitting on your side of the table directly facing off against the auditor. We’re providing the answers to their questions, the necessary artifacts, and evidence to get you to that 110 score. And realistically, we’re hoping to answer those questions before they’re asked, driving confidence with the auditors that we have all our I’s dotted and our T’s crossed.”
For DIB organizations, it’s the most reliable path to success.
What Contractors Must Do Now to Build a Sustainable CMMC Compliance Program
The following 10 actions consistently distinguish the organizations who build and sustain a compliance program that meets CMMC requirements from those who don’t.
- Build the three‑team compliance model. No single person or department can do this alone. Compliance requires coordinated execution across governance, security operations, and IT.
- Use NIST 800‑171A for your gap assessment. It’s the standard auditors use. If your assessment doesn’t map to the 320 assessment objectives, you’re not preparing for an audit—you’re preparing for disappointment.
- Make compliance a continuous operation. Evidence must be collected monthly and quarterly—not right before an audit.
- Maintain an accurate, detailed SSP. It’s the first document auditors request and the backbone of your evidence.
- Operationalize incident response. Develop the plan, run a tabletop annually, update it, and preserve the record.
- Stand up 24×7 U.S.‑based monitoring. Many contracts require U.S.‑citizen analysts and sovereign operations.
- Establish vulnerability management with remediation SLAs. It’s not enough to scan—you must prove timely remediation.
- Strengthen IT baselines and change management. IT owns most of the controls and often represents the largest audit risk.
- Remove non‑compliant vendors. If your provider isn’t compliant, neither are you.
- Talk to the DFARS/CMMC compliance experts. It’s best to know what you really need first in order to avoid overspending on software licenses.
These actions rooted in evidence, documentation, and process discipline are the foundation of a sustainable CMMC program that won’t fall apart under audit pressure.
The Bottom Line: CMMC Compliance Takes a Village
The most important truth contractors must embrace is this: “It is a team‑based approach, and it truly takes a village.”
CMMC Level 2 compliance is about demonstrating, with evidence, that your organization is doing what it says it does every single day. It requires an interconnected ecosystem of compliance advisory, security, and IT.
That’s the approach we’ve refined for more than a decade, exclusively serving the Defense Industrial Base. CyberSheath’s CMMC Managed Services exist for one reason: to give DIB contractors a reliable, proven path to securing their contracts and sustaining compliance year after year.
