CMMC Level 2 “Self-Assessment” (OSA)

Utilizing a Certified CMMC Lead Assessor (LCCA) to assist companies in performing their  CMMC Level 2 Self-Assessment offers a structured and expert-guided approach to compliance preparation. An LCCA, with their deep knowledge of the Cybersecurity Maturity Model Certification (CMMC) framework, providing objective insights into the 110 security practices and 320 Assessment objectives across 14 domains required for a CMMC Level 2 Assessment. By collaborating closely with the organization’s team, the LCCA helps identify gaps in documentation, processes, and controls early in the self-assessment phase, ensuring that the internal evaluation aligns with official assessment standards. This partnership not only accelerates the self-assessment timeline but also builds internal capacity, empowering companies to produce a more accurate and defensible affirmation statement without relying solely on internal resources that may lack certification expertise.

One of the primary benefits of engaging an LCCA is the opportunity to conduct a “dress rehearsal” that simulates a real CMMC Level 2 assessment. During this mock evaluation, the LCCA applies the same rigorous methodologies, interview techniques, and evidence review processes used in formal third-party assessments, allowing the organization to experience the full scope and intensity of the process. This rehearsal uncovers hidden weaknesses—such as incomplete POA&Ms (Plans of Action and Milestones) or inconsistent control implementations—that might otherwise go unnoticed in a standalone self-assessment. By mimicking the actual event, companies gain hands-on familiarity with assessor expectations, reducing surprises and enhancing readiness for eventual certification.

Ultimately, the “dress rehearsal” with an LCCA delivers significant value by providing the authentic look and feel of a CMMC assessment without incurring the full financial cost of a formal certification audit or the severe consequences of deficiencies. Organizations avoid the high stakes of failing a domain, which could delay market access, jeopardize contracts with DoD prime contractors, or result in costly remediation under scrutiny. Instead, this low-risk simulation enables targeted improvements in a controlled environment, often at a fraction of the certification expense, while boosting team confidence and compliance maturity. The result is a smoother path to successful self-attestation and future third-party validation, safeguarding business opportunities in the defense supply chain.
