To bolster consumer trust in the foundation of ecommerce before it was irreparably damaged, several CAs and browser vendors came together to establish a higher security approach based on common standards: Extended Validation SSL certificates.
EV SSL is universally supported by all desktop browsers and provides an EV trust indication. All mobile browsers support EV SSL and some provide an EV indication.
Extended Validation SSL certificates have the highest impact on consumers, reassuring them that the site they are visiting is legitimate through visual cues in un-modifiable parts of the browser interface “chrome.”
For example, the latest versions of Microsoft Internet Explorer, Google Chrome, Mozilla Firefox, Opera and Apple Safari display the corporate name with a green background for sites protected by an Extended Validation SSL certificate.
