1. At least one non-transitory computer readable medium comprising computer readable instructions which, when executed, cause at least one processor of a first network security platform to at least:
buffer a query from a second network security platform for a cryptographic session key until at least receipt of the cryptographic session key from a server, the cryptographic session key associated with an encrypted network traffic flow between the server and a client, the server and the client to be different from the first network security platform and the second network security platform, the first network security platform to be identifiable as a recipient of the cryptographic session key from the server based on a platform selection value, the platform selection value based on a first parameter value associated with a first message from the client and a second parameter value associated with a second message from the server;
store the cryptographic session key from the server; and
after the receipt of the cryptographic session key from the server, generate a response including the cryptographic session key to send to the second network security platform.
