Yes, NetResults Tracker is a standard web application and as such it is visible to any browser that can access the web server. It is recommended that if you do expose NetResults Tracker to the Internet, that you apply a level of security on the NetResults Tracker pages using your web server. Since NetResults Tracker is simply a set of web pages that sits behind the web server, you can apply any security to NetResults Tracker that you apply to your web server (domain filtering, port number, authentication, etc.). Filtering by IP Address can be configured within Tracker itself. Information on setting up security on your web server using authentication can be found in the following section of our help file Adding a Workgroup.
