Abstract
A first example network security platform disclosed herein includes a platform selector to determine a platform selection value based on a first parameter value in a first message from a client and a second parameter value in a second message from a server, the first and second messages associated with establishment of an encrypted network traffic flow between the client and the server. The example first network security platform also includes a key retriever to obtain a cryptographic session key associated with the encrypted network traffic flow from a selected one of a cluster of network security platforms based on the platform selection value, the first network security platform included in the cluster of network security platforms. The example first network security platform further includes a traffic analyzer to analyze network traffic associated with the encrypted network traffic flow based on the cryptographic session key.
