DigiCert Wildcard SSL Certificates (Entire Domain)

What is a Wildcard Certificate?

SSL Certificates for Unlimited Servers and Subdomains

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.

Strongest Encryption Available

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 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.

Increased Conversions

Studies show that 63% of online shoppers will not purchase from a site that is lacking a visible trust seal. All DigiCert certificates come with a free site seal.

Around-the-Clock Certificate Issuance

DigiCert has a dedicated validation team that works around the clock to process your certificate request as quickly as possible, usually in less than an hour.

Useful Tools

Gain access to SSL Installation Diagnostics Tool, SSL Utility for Windows, and other tools that will help you manage your SSL Certificates.

Unlimited Duplicates

DigiCert's unique duplicate feature allows you to issue copies of your certificate to all of your servers, each of which is assigned its own private key.

Streamlined Maintenance

By using a Wildcard Certificate, you don't have to manage multiple certificates and expiration dates. Save time and money with a DigiCert Wildcard certificate.

Have you looked into DigiCert's Enterprise Managed PKI?

If you have a complex enterprise environment, with a variety of certificate to issue and manage, you should investigate whether Managed Public Key Infrastructure (MPKI) provides the ideal solution. DigiCert's MPKI allows you to oversee the certificates across your network and manage key lifecycle tasks from a central console. Combining PKI and Certificate Authority functions can reduce costs and admin time, increase oversight, improve security, and lessen the chance of costly mistakes.
