Everything You Expect from an SSL Certificate, Plus...

Learn more about DigiCert's SSL Plus Certificates

Single-name SSL Certificates provide encryption and authentication for one domain. DigiCert SSL Certificates have all the features you expect from an SSL Certificate (like strong encryption and browser trust) as well as a few things you won’t get anywhere else—like unlimited reissues, unlimited duplicate certificates, and an unlimited server license. And because of DigiCert’s innovative use of Subject Alternative Names, a certificate for www.yoursite.com will also work with yoursite.com. That’s why we call it SSL Plus.
