Scope before architecture decisions
Minimize unnecessary CUI scope before deciding that the whole company needs a government-oriented environment.
CMMC Level 2 scoping includes CUI Assets and relevant Security Protection Assets and has defined treatment for Contractor Risk Managed Assets, Specialized Assets, external service providers and Out-of-Scope Assets. The boundary requires analysis; it is neither automatically the entire company nor only the systems that directly store CUI.
Where business workflows permit, a secure CUI enclave can confine protected email and file sharing to a smaller set of users and systems. That can reduce unnecessary implementation and operating cost because fewer assets may require CMMC-specific treatment.
PreVeil is one enclave option. PreVeil publishes FedRAMP Moderate Equivalency and FIPS 140-3-validated AES-256-GCM cryptography information and is designed to run alongside Microsoft 365 or Google Workspace. Cyberneza is a PreVeil referral partner and can scope, deploy and document the enclave.
No enclave product makes an organization CMMC compliant by itself. The actual scope still has to satisfy 32 CFR 170.19, and the remaining NIST SP 800-171 requirements still have to be implemented and evidenced.
