# Defense Contractors Implement CMMC Level 2

Contractors working through CMMC Level 2 implementation describe a documentation- and compliance-intensive effort whose duration and workload vary with each organization’s environment, staffing, management support, and scope. Some commenters reported multi-month work and substantial overtime; one solo implementer said they completed the effort in two months using PreVeil VDI, with interviews trending MET across all 110 requirements. That individual experience is not a dependable schedule benchmark for other contractors.

- Contractors should plan staffing, management decisions, and documentation work around their own systems and scope rather than relying on a single reported implementation timeline.
- PreVeil VDI is cited as part of one implementer’s approach, but the signal does not establish that the tool or timeline will produce similar results elsewhere.
- Procurement and program teams can use these experiences to account for implementation effort when planning contractor readiness, schedules, and support needs.
