Drupal is Open Source
Drupal is open source software maintained and developed by a community of hundreds of thousands of users and developers. It's distributed under the terms of the GNU General Public License (or "GPL"), which means anyone is free to download it, share it with others, and contribute back to the project. This open development model means that people are constantly working to make sure Drupal is a cutting-edge platform that supports the latest technologies that the Web has to offer.
The passionate Drupal community is on hand to give support via various vibrant IRC channels, in the forums, and face to face at Drupal events. The community has also created Documentation for Drupal, which covers installation, site building, module building, theming, and many other topics. The worldwide community drives the innovation that makes Drupal the preferred choice for web developers and site owners. Drupal is open source, meaning everybody can get involved and make a difference.
We take security seriously and have a dedicated team that has a proven track record in dealing with your security issues professionally and efficiently, meaning you can spend more time creating your site.
As well as the community, there are many dedicated companies in the Marketplace on hand to help with your Drupal project. Providing expertise and a deeper understanding, they can help with hosting, spam blocking, training, and more.
