An SGC SuperCert is a chained SSL certificate and your web server must support certificate chaining.
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.
Thawte® SSL123 Certificates have the fastest issuance time to quickly enable encrypted connections to your web server. This domain-only validation SSL Certificate provides up to 256-bit encryption for web-based applications that are not at risk for phishing or fraud. SSL123 Certificates include domain authentication, the Thawte® Trusted Site Seal.
Web Server Certificate
Thawte® SSL Web Server Certificates secure confidential information exchanged online and confirm your site’s identity to employees, business partners, and other users. When users click the Thawte® Trusted Site Seal or view certificate details, your organization name appears and shows that Thawte, a trusted certificate authority, has verified the site’s identity. SSL Web Server Certificates include full organization authentication, the Thawte Trusted Site Seal.
WildCard Server Certficate
Thawte® Wildcard SSL Certificates secure multiple subdomains with a single SSL Certificate, reducing management time and cost. Using the wildcard notation (an asterisk and period before your domain name) allows you to extend security to different subdomains based on your top-level domain name. Wildcard SSL Certificates include full organization validation, the Thawte® Trusted Site Seal.
