1. A method, implemented by a computing system programmed to perform the following, comprising: invoking, by the computing system, a proxy agent in a virtual environment hosted by the computing system to obtain configuration change data for a virtualized application from an agent residing in a physical environment hosted by the computing system; changing, by the proxy agent hosted by the computing system, a configuration of the virtualized application based on the configuration change data to cause the virtualized application to load a plug-in in the virtual environment; and launching, by the computing system, the virtualized application in the virtual environment, wherein the virtualized application loads the plug-in in the virtual environment to utilize a function of the plug-in in the virtual environment, the plug-in being a data loss protection plug-in to prevent loss of protected data.
