cPanel is among the leading web hosting Control Panel instruments and it's used by millions of users globally. Its popularity is due to its user-friendliness and intuitive interface, that will enable you to access plenty of features with just a couple of clicks. You can move, copy and upload files, create new databases and add users with various stages of access, create e-mail addresses, enable spam security and SPF validation, view account usage stats, and a lot more. cPanel is used by many reseller website hosting providers, due to the fact that it contains a reseller-level Control Panel called WebHost Manager (WHM). The latter is a powerful tool which will enable you to create web hosting plans and to select all of their features. You can also set up and adjust client website hosting accounts, access and edit a lot of server-side settings and DNS zone records, install modules and apps, and much more. cPanel and WHM can be used with a lot of billing apps.
