An SSL Certificate (Secure Sockets Layer), also called a Digital Certificate, creates a secure link between a website and a visitor's browser.
Why is an SSL Important?
By ensuring that all data passed between the two remains private and secure, SSL encryption prevents hackers from stealing private information such as credit card numbers, names and addresses.
An organisation needs to install the SSL Certificate onto its web server to initiate a secure session with browsers. Once a secure connection is established, all web traffic between the web server and the web browser will be encrypted.

How Do I Know if My Storefront is Secure?
When a certificate is successfully installed on your server, the application protocol (also known as HTTP) will change to HTTPS, where the ‘S’ stands for ‘secure’. Depending on the type of certificate you purchase and what browser you are surfing the internet on, a browser will show a padlock or green bar in the browser when you visit a website that has an SSL Certificate installed.

Additional Information about SSLs
We would always recommend installing an SSL certificate on your site for your customers' piece of mind, but, also, Google now ranks websites based on their security ratings (Sites which are served through a standard http connection as opposed to https are instantly ranked lower in Google's new algorithm).
