System administrators use WHM to perform server administration functions:

  • Create, manage, and monitor cPanel accounts.
  • Configure networking information.
  • Manage SSL certificates.
  • Monitor and restart services.

Get started with cPanel

Website owners use cPanel to perform website management functions:

  • Manage individual domains.
