I noticed in the Triton console that I had an alarming number of users running Firefox 12. (Web Security -> Main -> Reporting -> Applications.) After some research, I discovered that IE11 mis-reports its user agent as part of Compatibility View (see http://blogs.msdn.com/b/ieinternals/archive/2013/09/21/internet-explorer-11-user-agent-string-ua-string-sniffing-compatibility-with-gecko-webkit.aspx). Perhaps Websense could periodically download the iecompatlistview.xml file to update its signatures, or use some other heuristic to determine browser version? Thanks.
