Systems and methodologies that proactively push down and enforce policies of a server(s) on mobile devices, when such devices connect to the server(s) for data synchronization. The subject invention employs a policy delivery and enforcement logic that is integrated as part of a communication channel (e.g. a single communication channel) with the mobile device(s). A hand shake can take place between the mobile devices and the server every time that a new policy occurs. Accordingly, non-compliant devices are denied service from the server.
