Cyber AB CCACertified CMMC Assessor
Cyber AB CCA (Certified CMMC Assessor) is the credential required to lead CMMC Level 2 assessments of US Department of Defense contractors under CMMC 2.0, which entered DoD's contract clause rulemaking in 2024. Assessors evaluate defense industrial base (DIB) companies against the NIST SP 800-171 control set before those companies can win or retain DoD contracts involving Controlled Unclassified Information (CUI). CCP is a hard prerequisite, as is eligibility for a DoD background investigation. CCA holders work for C3PAOs (CMMC Third-Party Assessment Organizations) accredited by Cyber AB to perform certified assessments.

Who it’s for
Built for the people taking this exam.
Senior GRC and audit professionals working at C3PAOs, defense-contractor security leads, and consultants preparing to lead CMMC Level 2 assessments of DoD contractors. Requires CCP certification, DoD background investigation eligibility, and Cyber AB-approved training first.
Why it matters in 2026
The career signal.
CCA is the only credential that authorizes someone to conduct certified CMMC Level 2 assessments. Once DoD's CMMC contract clauses are fully phased in, every DIB contractor handling CUI must be assessed by a CCA-led team, creating durable assessor demand. C3PAO assessor day rates are well above standard audit consulting rates because the supply of CCAs is gated by the C3PAO accreditation pipeline.
Sample question
What a Cyber AB CCA question looks like.
A government contractor permits employees to use mobile devices—such as tablets and smartphones—to handle CUI-related design files. Your review of AC.L2-3.1.18 confirms the contractor keeps a thorough log of all mobile devices connecting to its systems. AC.L2-3.1.19 mandates encryption of CUI on mobile platforms; the contractor currently applies full-device encryption. Which of the following best explains why you might recommend container-based encryption instead of full-device encryption?
Why: Containerization restricts encryption to specific apps and their associated data rather than the entire device. This targeted approach enables fine-grained control over which data is protected and who may access it—for example, a work email app can be secured without touching personal photos or banking apps. Full-device encryption can degrade performance during boot and decryption cycles. Encrypting only the container minimizes that impact. In BYOD environments, containerization lets organizations protect work data without requiring access to employees' personal information, creating a clear boundary between professional and personal content.
