Prism Open Source works with a number of partners, who are very important to us. We want to give you the chance to review them, to see on which parties we rely for services.


Squirrelmail was the first Open Source application in our portfolio. Prism Open Source is proud to be one of their first Commercial Service Providers. Squirrelmail is a very popular and widely used application. They continue to be a very active part of the Open Source Community and we continue to be a part of the development process of Squirrelmail.
