Where the U.S. Department of Defense accepts this

The DoD lists this certification as an approved foundational qualification option for 7 cyber work roles, per the DoD 8140 qualification matrix (V2.1, effective 2025-09-19; checked 2026-08-07). These are work-role classifications, not job openings, not hiring eligibility, and not evidence that these roles are available to you.

Mapped at advanced proficiency

  • Network Operations Specialist 441
  • Cyber Defense Analyst 511
  • Cyber Defense Infrastructure Support Specialist 521
  • Cyber Defense Incident Responder 531
  • Enterprise Architect 651
  • Security Architect 652
  • Information Systems Security Manager 722

This covers the foundational step only. DoD 8140 qualification has more than one part: a foundational qualification, then a resident on-the-job qualification within the role, then continuing professional development. A certification can satisfy the foundational part. It does not by itself qualify anyone for the work role.

It is also one route, not the required one. The DoD lists a qualifying degree, approved training, or a certification as alternatives to the same foundational baseline. And a certification approved at a higher proficiency level also applies at lower proficiency levels for that same work role, so the level shown above is where the matrix maps it, not a ceiling.

The matrix sets the department-wide baseline. A component, command, or contract may set stricter foundational requirements for a particular position, and environment-specific resident requirements are left to component discretion — so this cannot tell you what one specific job will ask for. Sources: the DoD 8140 qualification matrix V2.1 (XLSX) for the mappings, and DoDM 8140.03 (PDF) for the qualification lifecycle. IAT, IAM and IASAE levels belong to DoD 8570.01-M, which DoDM 8140.03 cancelled, and are not part of 8140.
