A common Microsoft 365 cleanup pattern before CMMC review

Engineering and technical-services firms often grow Microsoft 365 one project at a time. A few users get elevated admin roles, guest access is opened for outside partners, Teams sharing settings drift, and project files move between SharePoint, OneDrive, email, and local devices. Nothing looks unusual until a CMMC, NIST 800-171, prime-contractor, or cyber insurance review asks for evidence.

Quick answer

An engineering firm preparing for CMMC or NIST 800-171 should review Microsoft 365 admin roles, MFA, conditional access, guest users, file sharing, device access, email security, backup coverage, and evidence ownership before the deadline. BCT can help turn those findings into practical remediation tasks and supporting evidence.

FAQ

Is this a substitute for an assessor or compliance advisor?

No. This is an IT-readiness and evidence organization guide. Formal interpretation and assessment decisions should be handled with the appropriate advisor or assessor.

What should the owner review first?

Start with scope, systems, users, administrators, backups, endpoints, and the evidence that proves controls are operating. A tool list without owners and records is not enough.
