Evoq is a Content Management System (CMS) with powerful features, including page management, workflow, granular permissions, localization, caching and search.
We have an Open API (Application Programming Interface) that customers have used to extend the functionality of their sites via custom-developed modules. We also manage the DNN Store (http://store.dnnsoftware.com), which provides hundreds of commercially available (and supported) modules from third-party vendors. If you need to a feature on your site, look first to the DNN Store before building it yourself.
