The Biggest CMMC Mistakes Subcontractors Are Making Right Now
If you’re a subcontractor working with the DoD, you’ve probably heard about CMMC. But knowing about it and being ready for it are two very different things. Here are the most common mistakes we’re seeing and why they matter.
Mistake #1: Assuming Your MSP Has It Covered
Many businesses rely on their MSP for IT and security. That’s a good thing, but it doesn’t mean you’re CMMC ready.
CMMC requires:
- Specific documentation
- Defined processes
- Evidence of controls
Most MSPs don’t handle the full compliance picture.
Mistake #2: Thinking a Self-Assessment Is Enough
Self-assessments can be helpful but they’re NOT the finish line. Depending on your required level, you may need:
- Formal documentation
- Independent assessment
- Ongoing compliance practices
Checking boxes isn’t the same as being prepared.
Mistake #3: Underestimating Documentation
One of the biggest surprises for subcontractors is how much documentation is required. This includes:
- System Security Plans (SSPs)
- Policies and procedures
- Plans of Action & Milestones (POA&Ms)
Without these, even strong technical environments can fall short.
Mistake #4: Waiting Until It’s Urgent
This is the most common and the most risky. By the time a prime contractor asks for proof, you may not have enough time to prepare properly.
That leads to:
- Rushed fixes
- Higher costs
- Increased stress
What Subcontractors Should Do Instead
The goal isn’t to do everything at once. It’s to start with clarity:
- Where are you today?
- What’s missing?
- What needs to happen next?
Once you know that, everything else becomes manageable.
