umbraco is a free, stable and standard-supporting cms that is easy to use. You get the best from both worlds by having an open source cms that has a fully open api, full source code included, a helping and growing community and still you have that great .NET platform backed up by Microsoft. You can get professional assistance from consultants in many countries and through umbraco professional services, you can always get help directly from the people who knows the software by heart.
umbraco is fast to learn for both developers and content contributors. It's based on the Microsoft .NET platform and is using w3c standard technologies like XML and XSLT for template building while still being fully open for integration using any .NET language like c#, VB.NET or Delphi. The editor interface is using well known metaphors making it a breeze to use for content contributors.
umbraco is already used and praised by large organisations and companies delivering hundreds of thousands of page views every single day.
We really believe that umbraco beats any cms on the Microsoft platform, and we've written why! If your boss are doubting umbraco, please ask him why. Send his worries to us and will give you and your boss an answer fast.
This is what umbraco is all about; you can't get any closer to the source, neither the code nor the people behind.
