In your GreggHost panel, you can add two types of certificates:
Sectigo certificate Paid ‘Let’s Encrypt’ certificate
The distinctions between these are discussed further down.
Free Let’s Encrypt SSL certificates
Let’s Encrypt is a Certificate Authority (CA) that provides free SSL certificates that are just as secure as existing paid certificates. However, for eCommerce sites, a purchased certificate is still suggested because ‘Let’s Encrypt’ certificates do not have ‘Organizational Validation.’ This project was started with the goal of making encrypted connections the standard on the Internet.

Paid Professionally-signed certificate ($15/year)
A self-signed certificate, as previously stated, causes a browser warning while visiting the site. A premium Sectigo certificate is highly recommended if you have a customer-facing site, or, more critically, a site that handles sensitive information like passwords and credit card data.
Paid certificates have no browser warnings and include additional information to confirm the certificate’s legitimacy. These certificates, for example, feature Organizational Validation (OV), which provides your users with additional assurance that the certificate was issued to a reputable business.

How can I get an SSL certificate that is signed by a professional?
The usage of an SSL certificate does not need the use of a unique IP address. However, if you want to use an eCommerce application, adding a Unique IP address is highly recommended to ensure optimal compatibility with outdated Internet browsers.
