CMMC Evidence Ownership

The readiness project ended, but the evidence work did not

Who should own CMMC evidence after readiness: the contractor, program owner, process owners, MSP, RPO, vCISO, or a managed evidence-operations provider.

Contractor responsibility cannot be outsourced away

Evidence production belongs with the process operator

Coordination is a distinct recurring job

Judgment and signature remain separate from coordination

Separate ownership into operating roles

“The CISO owns CMMC” is too broad to run the work. The security lead may own the program, but HR produces training records, facilities produces physical-access records, the MSP produces technical exports, procurement produces supplier records, and leadership approves policies and affirmation.

Program owner: maintains governance and resources.
Process owner: operates the activity that must be proven.
Evidence producer: creates or exports the evidence.
Evidence coordinator: requests, tracks, reviews form, files, and reports.
Qualified reviewer: decides scope and sufficiency.
Affirming official: makes the annual representation.

Why the work becomes nobody’s job

Readiness consultants are typically engaged to reach a milestone. MSPs are paid to operate technology. Functional owners are paid to run HR, facilities, procurement, or delivery. Unless evidence coordination is explicitly assigned, each party assumes another party is maintaining the whole record.

Make ownership observable

Every recurring evidence set should have a producer, coordinator, reviewer, backup, cadence, approved source, and escalation owner. That operating detail is what turns responsibility language into a maintainable program.

Facts, not verdicts

Assigning an evidence coordinator does not transfer the contractor’s responsibility to implement requirements or the affirming official’s responsibility for the annual statement.

Questions buyers ask

Frequently asked questions

Should our MSP own all CMMC evidence?

The MSP should produce evidence for the services it operates. Organization-owned evidence and overall responsibility remain with the contractor.

Can Gridex be the evidence coordinator?

Yes, for an agreed scope and operating model. Gridex still does not become the assessor, implementer, or affirming official.
