Open Source and Drupal

The Leading Open Source Content Management Platform

Since Drupal 5 in 2007, we have been working with this open-source content management framework to offer a superior, cost-effective platform for sites with significant user, community and content management requirements. Drupal provides an enormous amount of functionality at the inception of a project, and can be tailored to the precise requirements of each client and user base.

The continuous development by the larger Drupal community of new modules and functionality also allows sites to continue to benefit from the platform's larger eco-system. ISL has contributed a number of Drupal modules, including ones for sales tax calculations, a module to restrict who can buy from an Ubercart store, and one to allow people to have public names that differ from their user names on a Drupal site.

This combination of factors has led us to specialize in Drupal development. ISL has built nearly 70 Drupal websites and is playing an important role in the spread of this platform.
