The invention provides a method for managing access to a network resource on a network from a mobile device, the method including the steps of intercepting a data stream from the mobile device attempting to access the network resource, extracting information from the intercepted data stream relating to at least one of the mobile device or a user of the mobile device, accessing at least one of enterprise service based information and third party information regarding at least one of the mobile device or the user of the mobile device, determining whether the mobile device is authorized to access the network resource, preparing an access decision that specifies whether the mobile device is authorized to access the network resource, and storing the access decision in a database on the network. The method may also include the step of enforcing the access decision by granting access to the mobile device to the network resource if the mobile device is determined to be authorized and denying access to the mobile device to the network resource if the mobile device is determined not to be authorized.
