So they are really highlighting--everything is encrypted, everything is this 128 bit security, everything has SSL security, all these acronyms and geeked-out terms to make you feel more comfortable.
Server optimization features such as SSL termination and compression technologies use specialized hardware to offload compute-intensive operations from the servers to the application delivery controllers.
Browser-based cryptography also means that anyone who breaks the SSL encryption that protects the data sent by the server could tamper with the code just as easily.
