Let’s Encrypt

Let’s Encrypt is a certificate authority (CA) that issues free SSL/TLS certificates you can use to secure your websites.

In Plesk, you can get a free Let’s Encrypt certificate with just a couple of clicks and do much more:

• Issue certificates out of the box (no setup or command line operations required).
• Secure domains, subdomains, domain aliases, and webmail with certificates.
• Renew installed certificates automatically.
• Receive email notifications about the certificate status (issued, renewed, about to expire).
• Secure Plesk itself.

Two Plesk extensions provide these features: Let’s Encrypt and SSL It! They are installed in Plesk by default and work in tandem: the Let’s Encrypt extension is integrated into the SSL It! extension as a CA plugin.
