TL;DR: Defense contractors pursuing CMMC Level 2 often spend 8 to 10 weeks assembling enclave architecture, identity configuration, logging, endpoint hardening, and validation before documentation begins, according to Secureframe. The underlying issue is not speed alone but how scope, identity, and evidence collection are governed once CUI is isolated.

By the numbers:
- Defense contractors pursuing CMMC Level 2 face a common challenge, and building a compliant enclave traditionally means 8 to 10 weeks of architecture planning, identity configuration, logging setup, endpoint hardening, and validation.
Questions worth separating out
Q: How should teams define the scope of a CUI enclave?
A: Teams should define the enclave by tracing where CUI is stored, processed, accessed, and logged, then excluding everything else from that boundary.
Q: Why do identity controls matter so much in a CUI environment?
A: Identity controls determine who can enter the enclave, what they can do there, and whether access can be proven during assessment.
Q: What do organisations get wrong about assessment-ready enclaves?
A: Many teams focus on infrastructure first and evidence later, which creates gaps between how the enclave was built and how it is inspected.
Practitioner guidance
- Define the CUI boundary before provisioning anything List every system, identity store, collaboration tool, and vendor that can touch CUI, then decide what stays inside the enclave and what stays outside.
- Separate enclave identities from corporate identities Create distinct admin and user accounts for enclave work, enforce MFA for all enclave access, and avoid shared roles that span both business and CUI environments.
- Use role-based access for enclave operations Limit who can upload, review, approve, and administer enclave content by role, then document those roles so assessment evidence matches actual privilege boundaries.

Assessment scope is the real control surface in CUI programmes. The article is really about collapsing a broad, messy environment into a defensible boundary that assessors can verify. That makes scoping decisions as important as encryption or logging, because every identity, device, and service that touches CUI can drag additional systems into review. Practitioners should treat scope definition as a governance control, not just an architecture task.
A question worth separating out:
Q: Who is accountable for keeping a CUI enclave compliant over time?
A: Accountability sits with the team that owns the enclave boundary, the identity model inside it, and the evidence that proves controls remained active. In practice that usually means security, IAM, and compliance leaders sharing ownership of scoping, access governance, and continuous monitoring.
