A method and system for securing data transmitted between a client device and a server by obtaining input text at an intermediate module, processing the input text to obtain processed text, and transmitting the processed text to the server. In particular, the server may be configured to provide at least one function on input data provided by the client device, and the intermediate module may be configured to receive input data from the client device, to transform the input data into processed data, and to transmit the processed data to the server. Embodiments of the invention may include systems and methods for intercepting the input data at the intermediate module without transmission of the input data to the server; providing the at least one function by the intermediate module on the input data; and generating by the intermediate module at least one message to the client device based on a result of the at least one function.
