Extended Validation triggers the display of the green address bar in the latest high-security browsers, and True 128-bit SSL Certificates enable every site visitor to experience the strongest SSL encryption available to them.
Certain older browsers and operating systems will not connect at the strongest encryption level available to them unless there is a Server Gated Cryptography (SGC)-enabled certificate on the server. VeriSign is the leading SSL provider of SGC-enabled SSL Certificates, enabling 128- or 256-bit encryption for over 99.9% of Internet users.
