Rising Stars are recognized for providing high-quality answers to other users. Rising Stars receive a certificate of achievement and are on the path to becoming Community Champions.
Atlassian does not own or provide that kind of product. It appears from reviewing their site over in http://docs.vnnox.com/display/VNNOXEN/3.4.1+Getting+Started that they are just using our product Confluence to provide their own documentation.
If their documentation is insufficient to answer your question, I'd suggest you reach out to them in their contact link of http://vnnox.com/contact
