The system and method for predictive modeling in a network security service described herein may provide a scalable architecture that can model information relating to any specific threat or potential threat in a network and manage routing requests relating to the threat information among various entities participating in the security service. In particular, the scalable architecture may include various distributed databases that store serialized information describing threat instances, wherein a detection service may maintain information identifying entities associated with the databases storing the serialized information. Further, the security service may include a hierarchical subscriber name service that participating entities can traverse to locate the serialized threat information in the various databases and evaluate how the threat instances may have evolved or progressed through the network.
