Security Wall improves the global Concrete5 security. Where does this improved security come from? The image on the left shows why Security Wall can improve the security of Concrete5. By boxing C5 inside a powerful security framework, C5 can block most of web-based attack. This is absolutely a great feature when a new C5 version come out and some exploit are released to public. Until you upgrade the C5 core it's very easy for people to attack your site (this happens for every CMS, not only C5). Security Wall is actually based on PHPIDS, a simple to use, well structured, fast and state-of-the-art security layer for your PHP based web application.
