Protect CUI the Way CMMC Requires

If you’re a small or mid-sized business working with the DoD, CMMC compliance is no longer optional. Starting November 10, 2025, new and renewed contracts may require you to prove you can protect Controlled Unclassified Information (CUI).

The challenge? Most SMBs don’t have the staff, budget, or time to manage compliance alone. That’s where Exostar comes in.

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.
