An intrusion prevention system includes a processor, processing engines, buffers that are associated with a different range of reputation scores, and a storage device having a database and an application. The processor executes the application to determine that a firewall has admitted a packet, determine a reputation score for the packet from the database, provide the packet to a buffer that has a reputation score range that includes the reputation score of the packet, provide the packet from the buffer to a processing engine, process the packet by in the processing engine to determine if the packet includes an exploit, and forward the packet to the protected network if the first packet does not include the exploit.
