Recently we changed the web hosting control panel we use from ISPConfig to Sentora on several of our servers at PinkTie Technology Group. Sentora is based on the old zPanel control panel which was purchased by Hostwinds and development came to a halt. Sentora is developed and maintained by the original members of the zPanel team.
Sentora brings a much more user-friendly interface for our clients along with some additional features. The user community is involved in the growth of Sentora and many great modules have been developed in addition to some previously created modules from zPanel are compatible.
The documentation as with many similar projects could use some help, however anyone with experience with hosting control panels can quickly adapt. The configurations and source code are easy to navigate if you need to make any customization to your install.
Be sure to follow my tips, hints and guides for Sentora.
