Comparison with cPanel's AutoSSL

cPanel version 58 shipped with a feature called AutoSSL in August 2016. You can read about it here. For reference, our plugin was released at the start of December 2015, shortly after Let’s Encrypt went live.

FleetSSL cPanel does not integrate with the WHM AutoSSL framework, and works as a standalone plugin.

There is a cPanel-provided Let’s Encrypt AutoSSL Provider available if you wish to use AutoSSL with Let’s Encrypt.

Primary differences between AutoSSL and Let’s Encrypt™ for cPanel

The main difference between using an AutoSSL Provider and FleetSSL cPanel is that AutoSSL is designed to be fully automated in the background but less flexible, whereas FleetSSL cPanel is designed to give the user more control.

Feature	Let’s Encrypt™ for cPanel	cPanel AutoSSL
cPanel end-users can issue certificates via user interface	✔	✔ (users can request AutoSSL to run on their account)
DNS and HTTP (webroot) validation methods	✔	✔, since cPanel 74
Wildcard certificates	✔ (via DNS validation)	✔ (since cPanel 86, for wildcard virtualhosts only, via DNS validation)
Separate certificates for each virtualhost	✔	✘ (single certificate)
Automatic SSL for new domains in background	✔ (every 12 hours, disabled by default)	✔ (usually fast, delays vary)
Service certificates with custom domains	✔	✘
CLI and HTTP API interfaces	✔	✔

Your purchasing decision

cPanel’s AutoSSL is consistently improving its functionality and reliability and is probably a good choice for most users. We encourage users to consider whether cPanel AutoSSL can fully meet their needs.

We would suggest that FleetSSL cPanel provides a some functionality, flexibility and control that is not possible with cPanel AutoSSL.

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