What is an SSL certificate?

An SSL (Secure Sockets Layer) certificate is what secures data as it is transferred to and from your website in an encrypted format. Encryption is the process of scrambling data into an undecipherable format that can only be returned to a readable format with the proper decryption key.


Essentially, an SSL certificate serves as an electronic “passport” that establishes an online entity’s credentials when transmitting data. When one of your site visitors sends confidential information through your website, the visitor’s browser accesses the server’s digital certificate and establishes a secure connection.
