Who Audits the Auditors? The Wild Card in Your Next CMMC Assessment

CMMC has officially moved from “that thing we’ll deal with eventually” to “that thing in your current contract.” The urgency is real, and the stakes are high.

Lately, our clients all ask some version of the same question: “If we do all the work, are we actually going to pass?”

Usually, you’d expect a straight “yes” if you’ve checked the boxes. But thanks to a recent (and oddly quiet) report from the DoD Office of Inspector General (OIG), the real answer is: It depends on who walks through your door.

The “Oversight” Gap

Earlier this year, the OIG took a hard look at the CMMC ecosystem. Their findings weren’t exactly a ringing endorsement. They found incomplete documentation and inconsistent vetting for the very people tasked with auditing you.

In plain English? The process for validating the auditors themselves is still a work in progress.

This matters because it confirms what many of us suspected: Assessments aren’t going to be a perfect science. On paper, a control is either “met” or “not met.” In reality, you’re dealing with human beings, varying levels of expertise, and—as the OIG pointed out—a system that is still maturing.

If You’re Explaining, You’re Losing

In a perfect world, your security stack would speak for itself. In an actual assessment, there is a lot of “theatrical” back-and-forth. We’ve seen perfectly implemented controls fail—not because the security was weak, but because the evidence was a mess.

If an auditor has to go on a scavenger hunt to find where a policy connects to a specific server, you’ve already lost the momentum. You end up spending your time justifying your existence instead of demonstrating your compliance.

The most common friction points we see:

• The “Trust Me” Defense: Relying on verbal explanations (“That’s just how we do it”) without a paper trail to back it up.

• Frankenstein Policies: Great policies that were clearly copy-pasted and don’t actually match how your team operates on a Tuesday afternoon.

• Data Scavenger Hunts: Evidence buried in five different systems with no map to connect them.

The “Airtight Case” Strategy

Up until now, your CMMC journey has likely been internal—lots of self-assessments and readiness reviews. But when a third-party auditor arrives, they don’t know your “vibe” or your history. They have a limited window of time and zero patience for “piecing it together.”

We tell our clients to treat an assessment like a trial. You need a clear, undeniable line from Requirement → Implementation → Evidence.

Before your auditor shows up, you should be able to sit down and show:

1. Exactly what the requirement asks for.

2. Exactly how you’ve solved it.

3. Exactly where the proof lives.

If you have to jump between four browser tabs and “circle back” to a question later, you’re creating room for doubt.

The Bottom Line

CMMC is often treated as a “build” exercise—set up the environment, write the docs, and cross your fingers. That’s only half the battle. The other half is verifiability.

The OIG report is a helpful reminder that you can’t assume every auditor will be a seasoned pro or even consistent with the last one. You have to make your compliance so obvious, so well-mapped, and so easy to follow that the auditor’s own “maturing processes” can’t get in the way of your certification.

Don’t just build a secure environment. Build an undeniable one.
