CMMCCMMC certification is now a requirement for defense contractors handling Federal Contract Information or Controlled Unclassified Information. Without certification, you cannot bid on or maintain DoD contracts — the clock is ticking to get compliant.
Defining the CUI boundary across networks, systems, and facilities — especially when defense and commercial work share infrastructure.
Implementing all 110 NIST SP 800-171 controls for Level 2, many of which require significant technical and process changes.
Limited availability of accredited C3PAO assessors means wait times of 6-12+ months for formal assessments.
Comprehensive System Security Plans, POA&Ms, and control evidence that assessors expect to review.
Lack of MFA implementation across all CUI-touching systems, especially for privileged access and remote connections.
Using commercial encryption rather than FIPS 140-2 validated encryption modules for CUI at rest and in transit.
Insufficient centralized logging, log protection, and log review processes across the CUI environment.
Missing or untested incident response plans that specifically address CUI compromise and DoD notification requirements.
Including preparation, tooling, and assessment fees
Depending on current maturity and scope
Defense contractor CMMC costs vary based on current security maturity and environment complexity. Companies starting with low SPRS scores face higher remediation costs. Cloud enclaves (GCC High) can simplify compliance but add ongoing cloud costs. The C3PAO assessment alone typically costs $50K-$150K.
