As a Department of Defense (DoD) contractor or subcontractor, you’ve likely come across terms like FCI and CUI—but what do they really mean for your business? Understanding what is FCI, what is FCI data, and how CUI CMMC regulations apply is crucial to maintaining your eligibility for defense contracts.
At CMMC IT Support, a San Diego-based consultancy specializing in helping small and mid-sized defense contractors achieve and maintain CMMC Level 2 compliance, we’re here to make sense of these complex requirements.
If you’re unsure where your organization stands, you can schedule a free CMMC compliance consultation or call us today at 858-483-8770 for expert help.
What Is FCI?
So, what is FCI? FCI stands for Federal Contract Information, which the U.S. government defines as “information, not intended for public release, that is provided or generated for the Government under a contract to deliver a product or service.”
In plain terms, FCI data includes any non-public information shared between your company and the DoD in connection with a contract. It’s not classified—but it’s sensitive enough that unauthorized disclosure could pose risks to national security or give competitors an unfair advantage.
Common Examples of FCI Data
- Contract proposals and bids
- Performance reports
- Project timelines and deliverables
- Pricing or payment details
- Organizational or procedural documentation
Even if you’re not handling classified materials, if your company works with the DoD, you almost certainly handle FCI—and that means specific cybersecurity standards apply to you.
FCI Meaning and CMMC Requirements
The FCI meaning goes beyond just definitions—it determines your level of cybersecurity compliance under the Cybersecurity Maturity Model Certification (CMMC).
Under CMMC 2.0, organizations that handle only FCI (not CUI) are required to meet Level 1 compliance. This includes 17 basic cybersecurity controls derived from FAR 52.204-21, also known as the “Basic Safeguarding of Covered Contractor Information Systems.”
These controls include measures such as:
- Limiting system access to authorized users
- Protecting systems with updated antivirus and firewalls
- Using encryption for sensitive data
- Requiring strong password policies
While Level 1 is the entry tier of CMMC FCI compliance, it’s also the foundation for every contractor who wishes to continue doing business with the DoD.

What Is CUI and How Does It Differ from FCI?
Controlled Unclassified Information (CUI) is more sensitive than FCI. The government defines CUI as “information the Government creates or possesses, or that an entity creates or possesses for or on behalf of the Government, that requires safeguarding or dissemination controls.”
In simple terms, CUI is non-classified information that still requires a high level of protection because it could cause damage to national interests if exposed.
Examples of CUI
- Research and engineering data
- Technical drawings or schematics
- Personally Identifiable Information (PII)
- Export-controlled information
- System security or vulnerability data
CUI and CMMC: Level 2 Requirements
For contractors handling CUI, compliance moves to CMMC Level 2, which aligns with the NIST SP 800-171 standard. This includes 110 cybersecurity controls that focus on both technical and organizational safeguards.
Technical Controls Include
- Multi-factor authentication (MFA)
- Network monitoring and logging
- Encryption at rest and in transit
- Access control mechanisms
Organizational Controls Include
- Documented security policies
- Regular employee training
- Incident response planning
- Risk assessments and internal audits
If your organization handles CUI, you must perform a self-assessment against NIST 800-171, submit your score to the Supplier Performance Risk System (SPRS), and maintain a Plan of Action and Milestones (POA&M) for ongoing compliance.
Failing to comply can lead to serious consequences—loss of contract, financial penalties, and even violations under the Department of Justice’s Civil Cyber-Fraud Initiative.
Why CMMC FCI and CUI Compliance Matter in 2025
The DoD is ramping up enforcement of CMMC across all contracts in 2025. That means contractors who handle FCI or CUI must be prepared to demonstrate compliance—or risk losing eligibility to bid.
For many small and mid-sized defense contractors, this is where CMMC IT Support comes in. We specialize in helping organizations identify the type of data they handle and implement a custom roadmap for achieving compliance.
Whether you’re just beginning to explore what is FCI data or managing complex CUI CMMC requirements, we simplify the process with expert guidance and proven tools.
How to Tell If You Handle FCI or CUI
If you’re unsure which type of data you handle, here’s a quick guide:
| Type of Data | Definition | Key Regulation | CMMC Level | Example |
| FCI | Federal Contract Information – Non-public info created or shared under a government contract | FAR 52.204-21 | Level 1 | Contract proposals, invoices |
| CUI | Controlled Unclassified Information – Sensitive unclassified data requiring protection | DFARS 252.204-7012 / NIST SP 800-171 | Level 2 | Technical drawings, research data |
When in doubt, treat all contract-related information as FCI or CUI and protect it accordingly.
If your DoD contract includes FAR 52.204-21, you handle FCI. If it includes DFARS 252.204-7012, you handle CUI.
Consequences of Noncompliance
Failing to comply with FCI or CUI handling requirements can result in:
- Loss of contracts and future eligibility
- Financial penalties or legal action
- Reputational damage with DoD and primes
- Potential cybersecurity breaches and data loss
Even one overlooked control can cost your organization millions in lost opportunities.
