The Defense Department's testing and evaluation body has serious cybersecurity concerns when it comes to using commercial cloud offerings. The Office of the Director, Operational Test and Evaluation (DOT&E) wrote in its annual report for fiscal 2020 that it was "concerned with the cyber survivability" of the Defense Department's digital modernization strategy initiatives, such as the Defense Enterprise Office Solution (DEOS), a $4.4 billion contract for Microsoft Office 365 services with GDIT. "DOT&E is concerned with the cyber survivability of DMS initiatives and less so with their operational effectiveness and suitability," the report states, adding that DOD would need to do comprehensive cyber testing for commercial cloud platforms.
