5 CMMC Mistakes Manufacturers Can’t Afford to Make

As the Department of Defense (DoD) continues to roll out the Cybersecurity Maturity Model Certification (CMMC), manufacturers—especially those in the defense supply chain—are under growing pressure to meet compliance standards. But getting CMMC-ready isn’t just about checking boxes. It requires a strategic approach and avoiding costly missteps.

At MVP Network Consulting, we work with manufacturers across Western New York to help them meet compliance standards without disrupting operations. Here are five common mistakes we see manufacturers make—and how to avoid them.

1. Assuming CMMC Doesn’t Apply to You

Many small and mid-sized manufacturers think CMMC only applies to large defense contractors. The truth? If your company handles Federal Contract Information (FCI) or Controlled Unclassified Information (CUI), you’re required to meet CMMC standards—even if you’re a subcontractor. Waiting for a prime contractor or the government to tell you to comply is a risky move that could cost you future contracts.

2. Waiting Until the Last Minute

CMMC compliance is not an overnight process. It requires a full review of your current cybersecurity posture, implementation of required controls, and—depending on your certification level—a third-party assessment. Waiting until you’re in contract talks with the DoD or a prime contractor puts your business at a disadvantage. Planning early allows time to address gaps without rushing or overspending.

3. Treating CMMC as Just an IT Problem

Yes, cybersecurity is technical—but CMMC impacts your entire organization. From HR and procurement to operations and the shop floor, everyone needs to follow processes that support compliance. Successful manufacturers treat CMMC as a company-wide initiative and engage employees with regular training and clear security protocols.

4. Ignoring Physical and Access Controls

CMMC isn’t just about firewalls and antivirus software. It also requires physical safeguards—like restricting access to sensitive areas and ensuring visitor logs are maintained. Manufacturers often overlook physical controls in busy shop environments, which can lead to non-compliance during an audit. A comprehensive plan addresses both digital and physical risks.

5. Going It Alone

Navigating the CMMC framework can be overwhelming, especially for teams already focused on production schedules and customer demands. Partnering with a compliance-focused IT provider like MVP Network Consulting ensures you have experts guiding the process from start to finish. From risk assessments and remediation plans to ongoing monitoring, we help you stay compliant—and competitive.
