If you are a system admin, cPanel allows you to manage your servers in a few clicks. cPanel® and WHM® offers a robust API, several tools and scripts that automates and eases otherwise tedious system administration tasks like maintaining the server, account provisioning, managing server resources and license management.
cPanel and WHM provides complete automation of thousands of tasks with its most popular tools that aid in its installation and configuration, its integration with user's application using install File Generator option, monitoring account usage through CloudLinux technology, securing a server from within the security center, configuring security policies on a server-wide level, a reliable backup system that creates everything from full server to individual account backups, service and data restoration with just few clicks and tweak settings for controlling and configuring cPanel software settings without reading through cryptic config files.
Moreover, there's a lot of room to expand upon cPanel & WHM through the APIs. Because of this, many 3rd party developers have created plugins and add-ons like billing add-ons, firewall software and email tools which are provided in a single easy-to-use cPanel Application Catalog.
