Joomla is a very secure an robust system straight out of the box. It is trusted by hundreds of millions of users and is installed on millions of webservers.
But like any system it has to be properly configured and kept up to date. The server environment it lives on also needs thought and knowledge to make it as strong and secure as possible.
SoftForge can help you strengthen your existing infrastructure. If you have a site that is a Joomla site we can make sure its up to date with its security, add security extensions that we use on all our sites to improve what is already a good system and make sure that your site stays yours and the content stays as you intended.
