I am using hostingraja VPS server for my website. I used to share my admin details to developers, colleagues etc and my admin details will be controlled by everyone. But after moving to hostingraja their team members explained me about administrative privilleges which mean my admin details will only be controlled by me. They explained me about the importance of server administrative privileges. Which my old hosting provider failed to explain. And also i came to know about the firewall settings which are necessary for securing the website. Thanks to hostingraja support team for giving informative ideas and i hope the same service will be offered in the future
