Section 1511 of the FY2026 NDAA mandates that the Department of Defense procure mobile devices and services with enhanced cybersecurity protections—including end-to-end encryption, identifier mitigation, and continuous threat monitoring—for senior officials in sensitive roles. This requirement addresses the high-risk targeting of leadership devices, with solutions like BlackBerry SecuSUITE and UEM with Zimperium MTD enabling compliance, secure communications, and operational continuity in contested environments.
