Quantum computing and national security are inseparable. IonQ operates at the intersection of cutting-edge research and the defense industrial base, making rigorous cybersecurity compliance a core business imperative.

Assess CUI environments to meet CMMC boundary requirements, including network segmentation, access control, media protection, and FIPS-validated encryption, and evaluate cloud environments against CMMC scoping guidance. Implement technical controls across NIST 800-171 practice families, including MFA, audit logging, configuration management, incident response, and vulnerability management. Serve as a CMMC subject matter resource, contributing to compliance roadmaps, facilitating readiness workshops, and advising on DFARS flow-down requirements for subcontractors. Collaborate with legal and contracts teams to review FAR/DFARS clauses in new and existing contracts, flagging CUI obligations and CMMC level requirements, and coordinate on ITAR and EAR obligations as they intersect with CUI handling.
