Thanks for choosing our VPS Hosting! Sentora and zPanel are just two control panels our VPS Hosting supports. Once you've placed your VPS order with us and chosen either "CentOS 6.7 with Sentora" or "CentOS 6.5 with ZPanel" from the drop down and your order has completed, you will receive a "VPS Hosting Created" email with all of the info you need to get started. Your zPanel or Sentora log in page can be found by visiting your VPS IP address. Your VPS IP address, along with your zPanel and Sentora log in details, can be found in the "VPS Hosting Created" email.
