For Managed Service Providers (MSPs), supporting defense contractors on their CMMC journey is both a responsibility and an opportunity. The challenge lies in helping clients identify, protect, and govern their Controlled Unclassified Information (CUI) while meeting strict regulatory requirements like DFARS 252.204-7012 and NIST SP 800-171.
One of the most effective ways MSPs can add value is by gathering the right information upfront to configure Zero Trust data protection policies with solutions like XQ.
Why Intake Matters for CMMC and Zero Trust
CMMC isn’t just about passing an assessment—it’s about embedding security into daily operations. XQ’s policy-driven approach allows MSPs to align client practices with CMMC domains by controlling:
- Who can access CUI
- Which domains and vendors are trusted
- How attachments are handled
- What file naming and labeling policies must be enforced
- How projects and programs are segmented
But without a structured intake, MSPs risk missing critical details that drive these policies.
The MSP’s CMMC Client Discovery Framework
To make this process repeatable, MSPs should ask every client a consistent set of questions across these domains:
1. Client and Vendor Ecosystem
- Who are your primary defense clients and subcontractors?
- Which vendors or partners are authorized to receive CUI?
- Should access be restricted by domain (e.g., .mil, .gov)?
2. Domains and Communication Boundaries
- What are your official internal domains?
- Do you use separate domains for sensitive programs?
- Which external domains should be blocked from receiving CUI?
3. Attachments and File Sharing Policies
- What file types typically contain CUI?
- Should attachments be encrypted and revocable by default?
- Do you allow CUI in email bodies, or must it remain in attachments?
4. Groups and Access Control
- Which groups are authorized to access CUI (engineering, contracts, program management)?
- Should access differ for employees vs. vendors?
- Do some groups require read-only access?
5. Projects, Programs, and Segmentation
- What projects/programs involve CUI?
- Should CUI be segregated by program or contract number?
- Do ITAR/EAR restrictions apply (US Persons only)?
6. CUI Terms and File Naming Policies
- Do you require “CUI” or “FCI” in filenames?
- Do you enforce file naming standards (e.g., Project_CUI_Date_Version)?
- Should XQ block or relabel outbound files if the naming is incorrect?
7. Governance and Retention
- How do you classify data (FCI, CUI, Non-CUI)?
- Should CUI be geofenced (e.g., US soil only)?
- What’s your retention/deletion policy for expired contracts?
8. Oversight and Incident Response
- Do you need audit trails for CUI access?
- Should alerts trigger when CUI leaves approved domains or naming standards aren’t met?
- Who approves exceptions?
Standardizing the Intake with Templates
To make client onboarding efficient, MSPs can use a structured Excel or Word intake form. This ensures no compliance-critical question is missed and provides a clear mapping from business policies to XQ Zero Trust enforcement rules.
By systematizing discovery, MSPs:
- Reduce errors in policy creation
- Prove due diligence during audits
- Build stronger trust with clients
- Shorten time-to-compliance for CMMC
The Bottom Line
MSPs are uniquely positioned to guide contractors through CMMC by bridging compliance requirements with technical enforcement. Using an intake process designed for XQ policy creation, MSPs can transform complex regulatory needs into practical, automated data protection policies.
🔐 With the right questions asked, CUI stays secure, compliance stays intact, and clients stay mission-ready.
Frequently asked questions
How can a managed service provider help a defense contractor with CMMC?
A managed service provider (MSP) can help a defense contractor with Cybersecurity Maturity Model Certification (CMMC) by gathering the right information upfront and translating it into Zero Trust data protection policies with XQ. This bridges requirements such as DFARS 252.204-7012 and NIST SP 800-171 with technical enforcement, controlling who can access Controlled Unclassified Information (CUI), which domains are trusted, how attachments are handled and how programs are segmented.
What questions should an MSP ask a client before configuring CUI protection policies?
An MSP should ask consistent questions across eight areas: the client and vendor ecosystem, domains and communication boundaries, attachments and file sharing, groups and access control, projects and program segmentation, CUI terms and file naming, governance and retention, and oversight and incident response. Examples include which vendors may receive CUI, whether attachments should be encrypted and revocable by default, and whether ITAR or EAR restrictions apply.
Can XQ enforce CUI file naming and labeling rules?
Yes, XQ policies can enforce file naming and labeling requirements for Controlled Unclassified Information. During intake, an MSP determines whether a client requires CUI or FCI in filenames, which naming standard applies, such as Project_CUI_Date_Version, and whether XQ should block or relabel outbound files with incorrect names. Alerts can also be triggered when CUI leaves approved domains or naming standards are not met.
Why should MSPs use a standardized CMMC intake template?
A standardized intake form in Excel or Word ensures no compliance-critical question is missed and provides a clear mapping from business policies to XQ Zero Trust enforcement rules. By systematizing discovery, MSPs reduce errors in policy creation, prove due diligence during audits, build stronger trust with clients and shorten time-to-compliance for CMMC, turning complex regulatory needs into practical, automated data protection policies.
