SSL Plus™

Single-name SSL Certificates are the most basic type of SSL Certificate. They provide encryption and validation and cover one domain. DigiCert single-name 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 a certificate for www.yoursite.com will also work with yoursite.com. That’s why we call it SSL Plus. Learn more about single-name certificates »

Extended Validation SSL Plus™

The highest level of authentication makes Extended Validation SSL Certificates the ultimate in building trust through your website. DigiCert's EV Plus certificates use Subject Alternative Names to secure both www.example.com and example.com in one ssl certificate. That means your customers ge t the green bar in EV-enabled browsers with or without the "www." Learn more about extended validation »

Unified Communications (SAN)

Unified Communications (UC) certificates (also called SAN certificates) use Subject Alternative Names to secure up to 25 domains, sites, and subdomains with one certificate. For example, with a SAN certificate you can secure www.example.com, www.example2.com, www.example3.net, mail.example.net, dev.example2.com, etc. This makes UC certificates perfect for Exchange environments or any environment where you need to secure multiple names across different domains.

Extended Validation (EV) Multi-Domain

Extended Validation (EV) certificates use the highest level of authentication and were specifically created to boost customer confidence through EV certificate-only browser cues like the green address bar. For businesses with a high-profile brand, EV certificates are the most effective defense against phishing scams. With an EV certificate visitors can be sure you are who you say you are and complete s ecure transactions with confidence, decreasing cart abandonment rates. And EV certificates put your organization in a leadership position—a competitive advantage in the world of ecommerce. Learn more about EV multi-domain certificates »

Wildcard Plus™

Wildcard certificates secure a domain and all of its first-level subdomains. For example, a certificate for *.example.com secures www.example.com, mail.example.com, etc. A standard SSL Certificate would only secure www.example.com, requiring you to purchase an additional certificate for mail.example.com. And every DigiCert wildcard certificate comes with an unlimited server license, so you only pay once—whether you have one server or one hundred. Learn more about wildcard SSL Certificates »
