SGC SuperCerts

Strong SSL Encryption for the Most Site Users

Thawte® SGC SuperCerts help keep online transactions secure by enabling every web site visitor to experience the strongest SSL encryption available to them. Most SSL certificates are capable of strong encryption (128-bit or higher), however, certain older browsers and operating systems cannot step-up to 128-bit encryption unless an SSL certificate with SGC technology is used. SGC SuperCerts include SGC, full organization authentication, the Thawte® Trusted Site Seal, free reissues, and a 30-day money back guarantee.

Note: An SGC SuperCert is a chained SSL certificate and your web server must support certificate chaining.
