System architecture and methods for controlling improper network activity in a wide area network, where the system includes multiple service provider devices configured to provide communications service to attack vector devices. Each service provider device or plurality of devices is provided with at least one policy agent. The policy agent of each of the service provider devices is placed in communication with a security service system. The method includes detecting an improper network event using one of the policy agents and providing the security service device associated with that policy agent/service provider device with vector data characterizing the improper network event. The method further includes forwarding the vector data relating to the improper network event from the security service system to other of the security service systems, and from those to the policy agents in the other service provider devices. The method then inhibits the transfer of messages, data, or other forms of traffic corresponding to the vector data.
