At Unlimited Web hosting we take the security of both you and your users seriously. Which is why we provide LetsEncrypt functionality across all of our cPanel hosting and Plesk hosting accounts including reseller hosting. This includes wildcard certificates.


From September 30 2021, LetsEncrypts’ cross-sign DST Root CA X3 expired. So devices and operating systems that don’t trust the ISRG Root x1 certificate will no longer trust certificates and show “Not secure” warnings. This excludes some android devices were it will remain valid for longer.

Openssl 1.0.2 users must update to at least version 1.1.0 to avoid any issues. For more information about this update and its impacts please visit LetsEncrypts website.
