  • jSecure hides your Joomla administrator URL with a special key so that only you can access. The problem with Joomla is that anyone can tell if your site is Joomla by simply typing in the default URL to the administration area (i.e. www.yoursite.com/administrator). jSecure helps you hide the fact that your website is built with Joomla from prying eyes.
