The SGC SuperCert is thawte's strongest encryption certificate. It automatically steps up protection to a minimum of 128-bit encryption even if your customers use older browsers which have limited 40-bit or 56-bit encryption capabilities. 256-bit encryption can be enabled if your client's browser capability and the cipher suite installed on your web server are both 256-bit compatible.

thawte's SGC SuperCert delivers the best security for both the vendor and the user. Recent studies conducted by the Yankee Group showed that SGC-enabled certificates do deliver as described, thereby providing increased security for tens of millions of PC users if all e-commerce vendors were to use SGC-enabled certificates..
