While final assignments must ensure critical program requirements are met, we strive to manage scheduling with a balanced approach that respects our team members' personal needs alongside mission readiness.
  • Clearance: Active DoD Secret clearance, with the ability to obtain and maintain a TS/SCI.
  • Baseline Certification: Current DoD 8570 IAT Level II (or higher) certification, such as CompTIA Security+ CE, ISC2 SSCP, or SANS GSEC (or equivalent 8140 requirements).
