How a Manufacturer Can Reach CMMC 2.0 Compliance in 90 Days

vCISO services led the CMMC Level 2 readiness sprint end to end: a control-by-control gap assessment against all 110 NIST SP 800-171 Rev. 2 requirements, System Security Plan (SSP) development, and — for anything that couldn’t be fully closed inside the 90-day window — a Plan of Action & Milestones (POA&M) with a committed remediation date. CMMC Level 2 certification sits directly on top of that underlying NIST 800-171 assessment and SSP; a C3PAO assessor doesn’t score controls in isolation, they score whether the SSP accurately describes how each control is actually implemented in that specific environment.

AI-assisted documentation accelerated first-draft SSP language and control-to-evidence mapping — drafting the “how this control is implemented here” narrative for each of the 110 requirements from configuration data, log samples, and existing IT documentation, and producing a first-pass mapping between implemented controls and CMMC assessment objectives. None of that draft language shipped unreviewed: every AI-drafted narrative went through a two-stage human check, first for technical accuracy against the actual environment, then cross-checked against the specific NIST 800-171A assessment procedure a C3PAO assessor would apply. An SSP describing a control that isn’t really implemented, or implemented differently than described, is a direct path to a failed assessment — so the AI compressed drafting time, not evidentiary accuracy, and every finalized narrative carried an explicit reviewer sign-off.

Deployed a Zero Trust architecture scoped to CMMC’s access-control and system-and-communications-protection domains — network segmentation isolating CUI-handling systems from the general corporate network, identity threat detection and response (ITDR) tuned to the credential-based attack patterns the IA and AC control families exist to prevent, and privileged access management (PAM) to close the AC.L2 controls governing administrative and elevated accounts. A SIEM platform was stood up specifically to satisfy the audit (AU) control family: CMMC assessors expect documented evidence that log review, retention, and alerting are actually operating, not just that logging exists, and 24/7 SOC monitoring gave the deployment a live response function rather than an archive nobody watches.

Infrastructure modernization addressed the environment underneath the policy work: network segmentation to define a discrete CUI enclave, migration of CUI-handling workloads to Azure GovCloud, and a backup architecture with air-gapped, offline copies. That backup design maps directly to the contingency-planning (CP) and system-and-information-integrity (SI) control families — a requirement that on-prem backup running on the same network it protects cannot satisfy, since a ransomware event that reaches production also reaches a backup target that’s still network-reachable.
