A system and method for updating, monitoring, and controlling applications on a workstation. The workstation includes a workstation management module configured to detect the launch or request to access a network by an application. A workstation application server receives data associated with the application from the workstation. The application server module can determine one or more policies or categories to associate with the application by referencing an application inventory database. Once the application server module has the category or policy, it forwards a hash/policy table to the workstation management module. Upon receipt of the hash/policy table, the workstation management module applies the policy that is associated with the application to control network access by the application.
