For U.S. manufacturers, getting into Department of Defense (DoD) contracting can open doors to steady, long-term work. But there’s a key requirement you can’t ignore: cybersecurity.
If your company makes parts, assembles components, or works anywhere in the defense supply chain, you’ll likely need to comply with the Cybersecurity Maturity Model Certification (CMMC). At Seashore IT, we help manufacturers prepare for this important step so they can compete for contracts—and win.
In this post, we’ll break down what CMMC is, why it matters for manufacturing, and how to get started without the overwhelm.
Why the DoD Needs Secure Manufacturers
Modern manufacturing relies on digital systems—CAD files, CNC machines, ERP software, IoT devices—all of which can be targets for cyber attacks. The DoD wants to ensure that sensitive design files and production data are protected throughout the entire supply chain.
That’s where CMMC comes in. It’s a cybersecurity framework that all DoD contractors (and their subcontractors) must follow, based on how much sensitive information they handle.
What Is CMMC?
CMMC (Cybersecurity Maturity Model Certification) is a tiered system that ensures companies meet baseline cybersecurity requirements. Here’s a quick breakdown:
Level 1 – Foundational: Basic cyber hygiene (antivirus, password policies, etc.)
Level 2 – Advanced: Protecting Controlled Unclassified Information (CUI), aligning with NIST 800-171
Level 3 – Expert: Reserved for companies working on the most sensitive contracts
If your shop works with technical drawings, design specs, or controlled data, you’ll likely need Level 2 compliance.
What Is Controlled Unclassified Information (CUI)?
CUI includes technical information that, while not classified, still needs protection—things like:
Engineering drawings
Product specifications
Manufacturing process documents
Export-controlled data (e.g., ITAR)
If you receive or generate any of this as part of a contract or subcontract, you’re handling CUI—and CMMC applies to you.
How to Get Started: A Simple Roadmap
1. Assess Your Data
Figure out if your systems store or transmit CUI. If you’re receiving CAD files or technical specs from a prime contractor or the DoD, the answer is probably yes.
2. Conduct a Readiness Review
Get a clear picture of where you stand. Seashore IT can help you perform a CMMC readiness assessment to identify gaps in your cybersecurity setup.
3. Build a System Security Plan (SSP)
Document how you protect your data—everything from firewalls and access controls to how you manage updates and backups.
4. Create a Plan of Action & Milestones (POA&M)
This outlines what you still need to fix and how you’ll get there. It’s a working document that keeps your team (and auditors) on the same page.
5. Implement & Improve
Start closing the gaps—upgrade outdated systems, train employees, and tighten access to sensitive files.
6. Get Certified
Once ready, you’ll undergo a formal CMMC assessment through an authorized third-party assessor (C3PAO).
Why CMMC Isn’t Just Red Tape—It’s a Competitive Edge
Many manufacturers think of CMMC as a burden, but it’s also an opportunity. Being compliant:
Makes your company eligible for more contracts
Builds trust with prime contractors
Helps you protect your intellectual property
Sets you apart from competitors
In the coming years, CMMC will be required for most defense-related manufacturing work, whether you’re a prime or subcontractor. Getting started now puts you ahead of the curve.
