Embodiments described include systems and methods for encoding and decoding data for a network application. A client application may include an embedded browser. The embedded browser may establish a session with a network application. The client application may identify a policy specifying a type of data to encode upon input. The embedded browser may detect the type of data of an input field of the network application being displayed in the embedded browser. The embedded browser may, responsive to the detection and the policy, encode the data inputted into the input field or decode encoded data displayed in the input field.
