We built content management systems from scratch in the 90’s. It’s in our core, and we know that using one will make life MUCH easier for you. We’ve worked with all the big ones and some small ones too. Our favorite is WordPress, but we can use any CMS, even with your current design.
WordPress is used by 54.7% of all the websites whose content management system we know. This is 17.4% of all websites. – http://w3techs.com/technologies/details/cm-wordpress/all/all
There’s safety in numbers. Wordpress is constantly being developed and secured. Because of the large community of developers and trusted plugins, you can keep WordPress incredibly secure. It’s incredibly easy to use and extend. It’s the reason we stopped building our own CMS.
