Green address field – EV SSL
A green address line, as shown above, provides immediate visual feedback that the web address is secure and more so than other SSL certificates. This requires additional validation that you are who you claim to be on-line before a certificate is issued. No certificate provides more security than the EV SSL certificate.
Visitors to sites that have EV (Extended Validation) receive a green address line in their browser, which shows who are covered by the SSL certificate and who issued this. Older browsers do not support the green colour feature.
EV SSL certificates are unique in providing a green address field in the browser, which is a visual sign that the web site is secure. The EV SSL certificate is the culmination of work undertaken by the CA/Browser forum. CA/B Forum include leading CAs and browser providers, in addition to representatives from various juridical and security organisations, who have co-operated on defining guidelines and user instructions for the Extended Validation (EV) standard. The EV standard improves on-line transaction security and provides a more intuitive method to identify secure web sites for web users. Before each Certification Authority (CA) can issue an EV SSL certificate, it must comply with the guidelines issued by the CA/B Forum. While these guidelines are international, they are also specific to individual countries. CA determines the guidelines for other types of certificates themselves. When using an EV SSL certificate users will be confident that they know who receives the information they transmit.
