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.
For example, if your company runs yoursite.com, a Wildcard certificate could also secure news.yoursite.com, blog,yoursite.com and shop.yoursite.com.
Thawte Wildcard SSL Certificates include full organization validation, the Thawte Trusted Site Seal, free reissues and a 30-day money-back guarantee.
