1. A system for providing security to user-entered inputs, the system comprising:
a security device that is communicatively coupled between an input device and a processor of a user device, the security device being configured to:
receive a string of characters from the input device that correspond to inputs made by a user into a web browser or application on the user device that is in communication with an application server,
add at least one security character to the string of characters to generate a watermark string, and
transmit the watermark string to the user device, causing the user device to transmit the watermark string to a security server that is communicatively coupled between the user device and the application server,

wherein the security device is configured to format the at least one security character such that only the string of characters are displayed in the web browser or the application at the user device, and
wherein the transmission of the watermark string to the security server causes the security server to:
use at least one rule to identify the at least one security character within the watermark string,
compare the at least one security character to one or more security rules,
remove the at least one security character from the watermark string, and
