I'd like to secure Plesk with SSL

The e-mail and HTTPS-ports of our Plesk VPS'es are automatically secured using SSL (TLS v1.2). The certificate used for this is self-signed and containts information (countr, city, etc.) which does not match your own information.

As such we highly recommend using a certificate of your own, or Let's Encrypt (or to at least generate a new certificate). Plesk offers various options, which are explained in this article:

The certificate used to secure Plesk and your mail ports (except for Let's Encrypt) can also be used to secure your website. The steps for securing your website are explained at the end of this article.
