CMMC and NIST SP 800-171 readiness for small and mid-sized defense suppliers.
Why readiness budgets get spent twice
The result is paying two times, first to learn what is deficient and then to have it corrected, while your prime keeps asking where things stand.
A list of gaps does not make you ready. A shelf of unimplemented policies does not either. You are ready when the safeguards run on your actual systems, the written record describes them accurately, and a responsible party keeps the two in step. Droptine performs that hands-on work.

Common Questions
Official answer: Controlled Unclassified Information (CUI) is a U.S. government categorization for unclassified information that requires safeguarding or dissemination controls. It replaces older, fragmented labels like "For Official Use Only" (FOUO).
The requirement: Contractor systems that store, process, or transmit CUI fall under DFARS 252.204-7012 (safeguarding) and 252.204-7021 (CMMC). Your contract also carries a clause covering NIST SP 800-171 assessments: older awards use 252.204-7019 and 252.204-7020, and newer awards use 252.240-7997. Taken together, these require the 110 controls of NIST SP 800-171 Rev. 2 and whichever CMMC assessment your contract names.
Examples of CUI could be: Technical drawings, engineering schematics, blueprint files, software code, procurement documents, specifications for military components, etc.
Short answer: It’s time for remediation (closing the gaps) and building operational proof.
Review the POA&M: Look at your Plan of Action and Milestones (POA&M) to prioritize missing controls based on security risk and technical complexity.
Implement Missing Controls: This usually involves updating policies, configuring technical safeguards (like Multi-Factor Authentication, encryption, log monitoring), and training staff.
Gather Evidence: Compliance isn't just turning on software; it’s proving it works. You’ll need to generate evidence (logs, policies, training records, screenshots) for every single NIST 800-171 requirement before calling in an assessor.
That varies with your starting point.
Moving CUI into a ready-made enclave, hosted on a platform with FedRAMP Moderate authorization or its equivalent, can make a company assessment-ready within a few weeks.
Bringing an entire company network into compliance usually runs 6 to 12 months for a small or mid-sized supplier:
Months 0 to 3: gap analysis, boundary definition, platform selection, and first drafts of policies.
Months 3 to 6: technical build-out, including MFA, logging, access control, and system configuration.
Months 6 to 12: running the safeguards long enough to produce evidence, followed by an internal mock assessment.
Droptine supports both routes.
You complete the assessment your contract calls for and then keep the program running.
Level 1 (FCI only): a self-assessment, recorded in the Supplier Performance Risk System (SPRS) and affirmed each year by a senior company official. Level 1 is met or not met and carries no score.
Level 2 (CUI): a self-assessment score posted in SPRS with an annual affirmation. Third-party assessments by a C3PAO are suspended for now under class deviation 2026-O0025, so confirm the current requirement in your contract and with your prime.
After that: safeguards, documentation, and vulnerability scanning continue year-round. The SPRS affirmation is a signed statement to the government, so the score behind it must be accurate.
No. Droptine prepares contractors and is not a C3PAO, so we never perform certification assessments.
Cyber AB conflict-of-interest rules bar a single organization from both preparing a contractor's environment and certifying it.
Certification assessments at Level 2 are performed by an independent C3PAO listed on the Cyber AB Marketplace. Droptine's role is consulting, implementation, and managed services that prepare you, including support for your own self-assessment.
