"WildCard Plus" Certificate

DigiCert's WildCard Plus ssl certificates secure an entire domain -- a certificate for *.example.com will secure www.example.com, mail.example.com, and any other subdomain of example.com you can think of. We even use SANs to let your wildcard ssl certificate secure the base domain: example.com. And every DigiCert WildCard SSL Certificate comes with an Unlimited Server License, so you only pay once, whether you have one server or one hundred.

"SSL Plus" Certificate

Single-name SSL certificates from DigiCert have all the features you would expect (2048-bit strong encryption, browser trust) and a few things you might not get from other companies' basic certificates (30-day satisfaction guarantee, great customer support, unlimited free reissues, professional site seal). One thing that DigiCert was the first company to do -- and as far as we know, we're still the only one who does it -- is using Subject Alternative Names (SANs) to make your single ssl certificate for example.com also secure www.example.com (and vice versa). That's why we call it SSL Plus. Learn more about DigiCert's Single-Name Certificates.

"Unified Communications (SAN)" Certificate

Unified Communications Certificates (sometimes known as UC or SAN Certificates) use Subject Alternative Names to let you secure up to 25 server names with one certificate. These ssl certificates are perfect for Microsoft Exchange Server 2007 and Office Communications Server, and they've also proven useful for users of other platforms who need to secure multiple names across different domains. Plus every DigiCert UC Certificate comes with an Unlimited Server License! Learn more about DigiCert's UC Certificates for total network security.
