Not Sure if CMMC Applies to You?
If you handle defense-related drawings, specs, schedules, or contract data—then it likely does.
Take the QuizDefense runs on CUI
Keep your work moving. Protect it—and prove it.
You need customer drawings to prepare a quote. Your team needs technical details to complete the work. That information may contain Controlled Unclassified Information (CUI), information that is not classified but still needs specific protection.
Give your team a secure place to use that information and exchange it with authorized people. Get help building the evidence that supports your CMMC compliance.
You may already work with CUI—even if you don’t call it that.
Some of the information behind your everyday defense work may need specific protection. Recognizing it helps you understand how to handle it. Not every customer document contains CUI. Check your contract requirements and ask your customer when instructions are unclear.
What your customer sends you
A drawing or technical specification may contain CUI. Before using it, check for markings and handling instructions.
What you create from it
If you copy CUI into a new document or summary, that information still needs protection—even though you created the file.
What you share to get answers
A message or attachment may include CUI from the work you’re discussing. Use an approved way to share it with people who are allowed to receive it.
What changes when your work involves CUI?
Your team needs to know where it can use that information and how to share it safely. You also need records that show how you protect it. Start by understanding the requirements that apply to your work. Then identify where your team needs clearer instructions or additional support.

Everything You Need to Know About CMMC Compliance
Who Is CMMC For?
CMMC applies to organizations in the Defense Industrial Base that store, process, or transmit Controlled Unclassified Information. This isn’t limited to large prime contractors; every tier of the supply chain is included, regardless of size or function.
If you support federal or regulated programs using technical data, drawings, specifications, schedules, bills of material, test results, or contract-related performance information, you are very likely within CMMC Level 2 scope, even if that information is only exchanged occasionally or stored in email, shared drives, or production systems.
- Small businesses are not exempt. Even niche suppliers with only a handful of employees must comply if they handle CUI.
- Indirect exposure counts. You don’t need to be the original creator or owner of CUI. Receiving, storing, or transmitting CUI is enough to bring you into scope.
- Cloud services do not remove the requirement. Your environment must meet the appropriate CMMC requirements.
What Is CMMC?
Think of CMMC as your passport to DoD business. The Cybersecurity Maturity Model Certification (CMMC) is the DoD’s standard for protecting sensitive unclassified data. CMMC Level 2 is built on the 110 requirements in NIST SP 800-171 and for many organizations, will require third-party certification. Without it, you likely cannot win or keep DoD contracts. CMMC compliance software helps businesses achieve CMMC readiness faster.
What CMMC Level Am I?
When Do You Need to Be Certified?
As of November 10, 2025, CMMC requirements became enforceable through DFARS 252.204-7021. There isn’t one single deadline for everyone, but contracts will begin requiring CMMC Level 2 at different times. Waiting too long can mean crowded auditor schedules and missed opportunities to become CMMC compliant. Getting ahead now gives you a clear advantage, reduces operational disruption, and helps ensure your DoD business continues without interruption.

Where Does CMMC Apply?
CMMC applies to your entire environment—both in digital and physical environments, where CUI is stored, processed, or transmitted. This includes where you store files, how you collaborate, what devices you use, and how you control access. Exostar CMMC compliance solutions simplify this by moving CUI into a secure, cloud-based enclave designed to limit your assessment boundary. By reducing the scope, you can streamline preparation, minimize disruption, and accelerate readiness for assessment.

Why Does CMMC Matter?
It’s about more than compliance—it’s about national security and your bottom line.
Foreign adversaries have targeted U.S. defense technology for years, putting national security and allied partners at risk. The US Federal government created CMMC to reduce the loss of sensitive information and strengthen the entire supply chain. Non-compliance may mean losing your defense contracts and potentially millions in revenue. Meeting CMMC standards helps protect your company and contributes to national security.

CMMC Terminology & Definitions
CMMC (Cybersecurity Maturity Model Certification)
The US Federal government program to make sure all defense contractors meet specific cybersecurity standards. Think of it as the DoD’s “cybersecurity report card,” you must pass to keep or win contracts.
CUI (Controlled Unclassified Information)
Sensitive government information that isn’t classified but still must be protected.
Examples: technical drawings, purchase orders, or supplier data related to defense projects.
If leaked, it could still harm national security or military readiness.
NIST SP 800-171
A set of 110 security requirements published by the National Institute of Standards and Technology (NIST).
These are the “rules of the road” for protecting CUI, and CMMC is built on them.
DFARS Clauses (Defense Federal Acquisition Regulation Supplement)
Contract rules that require defense contractors to follow specific cybersecurity standards:
- 252.204-7012 → Protects CUI + requires reporting cyber incidents
- 252.204-7019 → Requires a self-assessment of NIST 800-171
- 252.204-7020 → Requires you to post your score in the government’s SPRS system
- 252.204-7021 → Requires CMMC certification at the time of award
Together, these clauses make cybersecurity and CMMC a mandatory condition for doing business with the DoD.
Keep your defense work moving—with protection you can explain.
Your team needs to use sensitive information to deliver for your customers. Make sure they have a secure way to do it and records that show how it’s protected.
Let’s discuss where your work gets difficult and what support would help you move forward.
