A web page running on a client computing device accesses a web application hosted by a remote server. The local application receives data from the web application. The client computing device uses a data loss prevention (DLP) policy to determine whether the web application is a sensitive web application. In response to determining that the web application is a sensitive web application, the client computing device restricts a capability of at least one of the local application or the client computing device to perform one or more operations associated with the data received from the web application.
