Abstract
Described embodiments provide systems and methods for selectively encrypting and decrypting portions of a network flow by intermediary devices. A first device may identify a protocol used by a network flow traversing the first device via one or more packets of the protocol. The first device may determine that a level of encryption for the network flow meets a predetermined threshold. The first device may receive networks packets to be communicated between a sender and a receiver. The packets may include a first portion that is encrypted and a second portion that has clear text information. The first device may encrypt the second portion of the one or more packets. The first device may forward the network packets with the first portion and the encrypted second portion via a tunnel to a second device for decryption of the encrypted second portion for forwarding to the receiver.
