cPanel provides a Free SSL Certificate called AutoSSL Certificate. AutoSSL provides SSL Certificate for your Domains hosted in WHM/cPanel free of cost. Once you enable the AutoSSL for any of the Domains, it will create the automatic request to auto-install and renew the SSL Certificate.

There are 2 types of SSL Certificate providers.

1. cPanel (powered by Sectigo)
   
   
2. Let’s Encrypt
