Your purchasing decision

We would suggest that if you are operating a web hosting business, or if you run any kind of multi-tenant cPanel server, then the Let’s Encrypt™ for cPanel plugin will deliver a superior experience to (and reduce your administractive burden relative to) cPanel’s AutoSSL.

If, on the other hand, you manage all of the accounts on your cPanel server yourself via root, cPanel’s AutoSSL feature may be a good fit for you.

As always, we offer a 72-hour trial (with extended trials available if required) so that you may evaluate both solutions.

Interoperability

There are no known incompatibilities between AutoSSL and Let’s Encrypt™ for cPanel. That said, it would not make a lot of sense to run both simultaneously.
