A free open source script, SeedDMS is based on PHP and MySQL, and many years of development have made it an easy to use but powerful Open Source Document Management System, but also mature and an enterprise ready platform for sharing and storing files.
You can easily update your application from inside the cPanel.
We use mod_security to add an extra layer of security on top of your web application.
With TrueHoster, you get the same application and configuration regardless of the hosting you are deploying SeedDMS to. This makes it easy to migrate between different servers using cPanel.
