What is an SSL Certificate?
SSL stands for Secure Sockets Layer, the protocol that creates a secure, encrypted connection between a browser and a server. To use it, you must first obtain a certificate and install it on your web server. Certificates are typically installed on pages that require end-users to submit sensitive information over the internet like credit card details or passwords. Example pages include payment pages, online forms and login pages.
Trusted SSL Certificates are issued by Certificate Authorities (CAs) and are available in three basic types – Domain Validated, Organization Validated and Extended Validation. Domain validated certificates are generally the least expensive and are issued after the CA has verified that the applicant has control of the domain named in the certificate. Organization Validated certificates are issued after the CA has verified domain control and conducted background checks into the company that owns the website. Extended validation certificates offer the highest level of trust to the end-user and turn the address bar green during secure sessions. EV certificates are issued according the guidelines set out by the CA/Browser forum.
