11. Citrix Citrix Systems in January 2015 restructured its U.S. sales organization and introduced specialties to its Solution Advisor program. The software vendor is transitioning from having four regional vice presidents in the U.S. to having three vice presidents. One of the vice presidents under the new structure will be in charge of all the geographic regions, the second will oversee enterprise accounts and the third will supervise networking accounts. Bringing Citrix's field sales managers under a single organizational structure will facilitate more engagement, company executives said, as well as cede more control to partners when appropriate. Citrix has also launched specialties in Virtualization, Networking Data Center, Mobility Management and Networking Apps and Mobile Security.
