Wildcard SSL

Simplify SSL/TLS server configuration to a single IP address

Ours is the only Wildcard certificate that can also support up to 250 Subject Alternative Names (SANs) allowing you to add other domain names and even unrelated Wildcard domains to one certificate.

Wildcard SSL

The Wildcard SSL Difference

The difference between a Wildcard SSL certificate and other SSL/TLS certificates is that other certificates, which are issued to a single Fully Qualified Domain Name (FQDN), (e.g., www example.com), can only be used to secure the exact domain to which it has been issued. A Wildcard SSL certificate is issued to a “Common Name” -- *.example.com, and a Subject Alternative Name (SAN) -- *.example.com allowing the certificate to be used for an unlimited number of subdomains across an unlimited number of servers. A single Wildcard SSL certificate secures one domain -- *.example.com, and unlimited subdomains -- www.example.com, buy.example.com, dev.example.com, mail.example.com, etc.

Entrust Wildcard SSL Certificates can also secure multiple Wildcard SANs. The SAN ensures that the Wildcard certificate works with or without a subdomain: *.example.com *.example.net *.sample.com .examplesample.com

The combination of flexibility and value gives system administrators the ability to easily add subdomains without the costs or tasks involved with deploying new certificates. Plus all Entrust Wildcard SSL certificates come with a website security bundle to find malware on your website and protect it from being blacklisted.

Why use the Entrust TRUSTWORTHY SITE SEAL?

Entrust Site Seal

Let your visitors know they are on a secure Web site, with the Entrust Site Seal. It’s been proven that customers have increased confidence and lower “abandonment” when you use a site seal. The Entrust Site Seal establishes your business as a safe place to do online business, giving users a higher level of trust.

In today’s business environment, it is imperative that organizations establish trust with their customers online. The best way? Let your visitors know you have taken steps to ensure the security of their information by clearly displaying the Entrust Site Seal.*

  • Posting the Entrust Site Seal on your Web site let’s your visitors know that you are committed to online security.
  • Unless you deploy Extended Validation Certificates, the only indication of a secure connection customers receive is a small lock on the bottom of Web browsers. Customers may not know to look for this lock, but will be assured by a security seal.
  • Reduces shopping cart abandonment and increases order completions.
  • Just by clicking the Entrust Site Seal, visitors can verify your site’s authenticity and certificate status.

Entrust is recognized as a trusted security brand for more than a dozen years, providing layered security solutions that help instill confidence for consumers, enterprise and governments. Now you can leverage that brand to help secure the identities of your own customers.

Your website’s security is our number-one priority. That’s why Entrust OV SSL Certificates feature ECC public key encryption in our root certificates. With support for SHA-2 algorithms, Entrust SSL Certificates protect your data by offering stronger security and increased performance.


Security providers work continuously to innovate technology to upend hackers who are diligent in their efforts to craft clever new ways to steal data. Advanced ECC, while not new, uses a different approach than standard RSA. RSA draws its strength by using increasingly larger logarithms, which take more time to process. ECC, on the other hand, relies on discovering a distinct logarithm within a random elliptic curve. The larger the elliptic curve, the greater the security. Using a random formula improves the encryption strength while a smaller logarithm increases the performance of digital certificates.


Stronger Keys

ECC uses a smaller algorithm to generate keys that are exponentially stronger than RSA keys.

Increased Performance

The smaller algorithm means less data is being verified between the server and the client, which translates to increased network performance. This is especially important for websites that experience a high level of traffic.


Entrust SSL Certificates using ECC technology are ideal for scenarios where server-load performance is critical, and site visitors and the Web/app server are known to be compatible with ECC keys.

The practice of using a single certificate, such as a Wildcard Certificate, to protect multiple servers has become more common because they’re more cost effective and provide an easier way to manage certificates. The flexibility of managing an unlimited number of subdomains to a single certificate is a nice advantage for system administrators who want to simplify SSL/TLS certificate management. However, there is a substantial risk to using Wildcard certificates without employing best practices that mitigate common vulnerabilities.


The fact that a single Wildcard certificate and its corresponding private key could be used on multiple servers, and can also be used with the appearance of legitimacy with either a fictitious or a fraudulent subdomain name leaves them open to vulnerabilities. Using a single Wildcard certificate to protect multiple servers requires exporting the key-pair from one machine and importing it into one or more other machines. This creates a security vulnerability because the private key now exists in multiple locations. Now the value of that one private key is much greater because it protects more resources.

This practice ultimately bypasses controls for those subscribers who rely on the certificate approval procedure to monitor the authorization of new servers and new domains.


There are two main attacks facilitated by multi-server certificates:

  • Eavesdrop: is where an attacker finds their way inside the network and gains the ability to intercept user traffic.
  • Impersonation: happens when an attacker impersonates a genuine resource within the domain. A victim is lured to a fraudulent resource in the certified domain through a phishing attack.

Properly managed Wildcard SSL certificates can provide increased flexibility for system administrators, but they do come with increased risk. Entrust recommends using proper safeguards when deploying Wildcard Certificates. Download the white paper for a more detailed analysis.
