Geotrust® Geotrust DV Wildcard SSL
GeoTrust DV Wildcard Certificate: A low-budget encryption solution for your domain and unlimited subdomains.
GeoTrust DV Wildcard Certificate is also known as GeoTrust QuickSSL Premium Wildcard TLS/SSL Certificate.
If you thought: a more advanced DV wildcard SSL/TLS certificate with the GeoTrust name (you know, it covers your main domain and an unlimited number of subdomains) would be a bit costly, you'd be wrong. GeoTrust DV Wildcard certificates are a fast and inexpensive solution to secure an unlimited number of subdomains for a single domain from Geotrust (a sub-brand of Digicert). It has 99.99% browsers and mobile compability with strong SHA2 or ECC signature algorithms supported. Best of all, it only takes minutes for a certificate issued. It comes with a $500,000 warranty for peace of mind.
This is the perfect choice for those on a budget who want to quickly secure their main and subdomains. Just use * in a common name field like *.example.com and this will cover your subdomains, files.yourdomain.com, login.yourdomain.com, account.example.com etc, as long as they are part of the exact same base domain.
