Thank you very much for your interest in our CMS!
Rebranding the CMS in the backend is possible only after express permission from our side. We are ready to provide you with this permission in the License Agreement if you could give us with some more details about your project and use of Sitefinity.
You can either open a new support thread for that, or contact our Sales department.
