Ryan McArthur
Defense Leadership
Ryan McArthur, until recently, was the Defense Information Systems Agency’s program manager for the Joint Warfighting Cloud Capability, a $9 billion contract aimed to deliver reliable cloud capabilities across the Department of Defense. In April, he left DISA to join Zscaler as federal CTO after serving more than two years as the leader of the $400 million program management office, which enlists more than 60 professionals responsible for engineering, cybersecurity, acquisition oversight, and managing work under the JWCC contract with its four vendors: Amazon, Google, Microsoft and Oracle. Notably, during that time, McArthur helped to dramatically reduce the standard acquisition timeline under the vehicle and oversaw roughly 50 task orders placed in the past year, with dozens more in the pipeline.
