Email security allows users to connect securely via a web browser. This is done through the support of the HTTPs protocol. In the process, a certificate is sent from the server (Email Security) to the client (the user’s browser). The user utilizes the certificate to encrypt and secure its communication to Email Security.
Email security includes a self-signed certificate. This is very handy because it allows encrypted communication without the requirement to install a certificate. However, a public certificate issued by a Certificate Authority (CA) is a better option because users accessing Email Security with a browser will not get an invalid certificate authority warning from the browser. This in turn helps prevent man-in-the-middle attacks.
The rest of this document describes the process to obtain and validate the certificate.
