HTML Guardain is the world's first and most popular solution for total website protection. It will encrypt your Html and script code and make impossible stealing and reusing them. It will protect your links from stealing and leeching, your images, applets, etc.
HTML Guardian will also keep all web content filters away from your site, which can increase visits to it several times.
Also, many additional protection options are available - you can disable right click, page printing, text selection/copying and offline usage of encrypted files. You can also add password protection and referrer check to them.
