SSL (Secure Socket Layer) is a protocol for encrypting data that is transmitted over the Internet. It is commonly used on websites where users are required to provide sensitive information, such as passwords or credit card details. When a browser is pointed to a website that has an SSL certificate installed on it, the browser performs an SSL handshake with the server to verify that the website is legitimate. Once verified, a secure session begins and the data transmitted between the browser and server is encrypted and secure.
What is a shared SSL certificate?
A shared SSL certificate is shared among many users, rather than being specifically used for one domain name.
This essentially provides the same level of security and encryption as purchasing a dedicated SSL certificate. However, because it's shared by many users, the URL does not look as professional or unique.
What is a dedicated SSL certificate?
A dedicated SSL certificate is purchased for a specific domain name and will only work with that one domain name. It is installed onto the server where the domains website resides and allows visitors to access the website securely via: https://your-domain-name.tld.
Most businesses prefer using a dedicated SSL certificate, as it appears more professional to visitors.
