SSL Certificates for Unlimited Servers and Subdomains

Learn more about DigiCert's Wildcard SSL Certificates

Wildcard certificates use Subject Alternative Names (SANs) to 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.

State-of-the-Art Data Encryption

One of the best ways to protect your website from brute force attacks is to use 256-bit encryption along with 2048-bit root certificates. This hybrid cryptosystem benefits from the best features of both symmetric and asymmetric encryption. DigiCert certificates use the most secure encryption available and support for both SHA-1 and SHA-2 algorithms.

Unlimited Server License

Most other Certificate Authorities’ SSL Certificates (including wildcard certificates) are only licensed for one physical server. But with DigiCert's unlimited server license, you can use your certificate on as many servers as you want. You can even generate separate certificates with unique key pairs for each server. That's the ultimate in flexibility.

Unlimited Duplicates

Using the same SSL Certificate across a number of servers introduces problems if one of your servers is somehow compromised, exposing a private key being used by all of the servers. DigiCert's unique "Duplicate" feature allows you to issue unique copies of your certificate to all of your servers, each of which is assigned its own private key.

24/7 Certificate Issuance

When you need a new certificate you can’t afford to wait around days or weeks for the typical Certificate Authority to get around to issuing it. In a worst case you’re left with a site that is lacking any protection for far too long—or best case—you need to spend time worrying about your order and babysitting the validation process. That’s why DigiCert employs a dedicated validation team that works around the clock to process your request as quickly as possible, often in less than an hour.

99.9% Wildcard Compatibility

DigiCert Wildcard Certificates are trusted by all common browsers, email clients, operating systems, and devices. Rest assured that not only are you using the most secure encryption available, but your customers are all able to access your site without issues.

Increased Website Conversions

A large percentage of the time and effort spent on your websites is being wasted if you aren’t prominently displaying an icon that demonstrates online trust. Studies show that 63% of online shoppers will not purchase from a site that is lacking a visible trust seal.* If you can’t establish confidence in your customers they are going to flee to your competitors who can ensure a safe online environment. To aid in your conversion rates, all DigiCert certificates come with a free site seal.

Complimentary 5-Star Customer Service

A lot of Certificate Authorities tout their “award-winning” customer service, but then you look at their customer reviews on SSLshopper.com and wonder how they can consistently be receiving only 2-star reviews. All you need to do is sit on hold for twenty minutes before finally talking to a hard-to-understand support rep who eventually needs to transfer you to a different department, and the ratings all start to make sense. In contrast, DigiCert’s award-winning customer support team is available 24/7 to answer your questions. No phone queues; no getting passed around like a hot potato. Call our support number and it will be promptly answered by a knowledgeable tech support rep who is going to stay on the phone with you as long as it takes to resolve your issue.
