1. A method performed by at least one hardware processor for dynamic threat protection comprising: dynamically receiving real-time contextual data from at least one data source associated with a client and a subscriber list, the real-time contextual data including subscriber-specific information; analyzing the real-time contextual data to determine a security threat score associated with the client, the analyzing including evaluating whether the subscriber-specific information received from the subscriber list is valid; assigning the security threat score to the client using the analysis; automatically applying a security policy to the client using the security threat score, the applying including: providing a higher quality of service to the client when the subscriber-specific information is valid; and providing a lower quality of service to the client when the subscriber-specific information is not valid; determining whether the security threat score assigned to the client is above a predetermined threshold threat score; and based on the determining, selectively analyzing, contents of data packets associated with the client for adherence to a predetermined standard, the data packets being carried between the client and a server by a data network.
