Understanding how Controlled Unclassified Information flows through your CRM is essential for CMMC compliance. This technical analysis maps the complete data lifecycle—from ingestion to archival—and identifies the control points where compliance measures must be applied.
This article provides technical depth for concepts introduced in our CUI-Safe CRM guide.
CUI Ingress Vectors
CUI enters CRM systems through multiple pathways. Each requires distinct controls.
1. Email Synchronization
Email sync is the highest-volume CUI ingress vector. When your CRM captures correspondence with government contacts, it ingests:
- Email body content (often containing contract details, technical requirements, pricing discussions)
- Attachments (statements of work, specifications, RFP documents)
- Metadata (sender/recipient information, timestamps, thread context)
The technical challenge: email sync typically operates with broad permissions and no content classification. See our analysis of email ingestion compliance risks for detailed mitigation strategies.
2. Manual Data Entry
Users enter CUI through:
- Contact records (government personnel with clearance information)
- Opportunity records (contract values, technical requirements, source selection data)
- Notes and activities (meeting summaries, call notes with technical discussions)
- File uploads (proposals, technical documents, past performance records)
3. System Integrations
CUI flows into CRMs through:
- ERP integrations (contract data, project information)
- Pipeline databases (opportunity data from SAM.gov, GovWin)
- Document management systems (proposal libraries, past performance databases)
- Calendar integrations (meeting metadata with government contacts)
CUI Propagation Within the CRM
Once CUI enters the system, it propagates through multiple mechanisms:
Record Relationships
CRM data models create relationship chains:
Contact (CUI: clearance level) → Account (CUI: contract ceiling) → Opportunity (CUI: technical requirements) → Activity (CUI: meeting notes) → Email (CUI: attachments)
Is your CRM leaking CUI?
Most defense contractors use commercial CRMs never built for controlled data. See how a CUI-safe CRM changes the equation.
