Multiple Subdomains Security with Unlimited Server License and Multiple Servers Installation at Lowest Cost

Encrypting your website and the sub-domains using individual SSL certificates will prove costly and time-consuming. But to avoid such scenarios, there's a Wildcard SSL certificate. A Wildcard certificate is a single SSL certificate that encrypts and provides SSL security for one main domain and unlimited first-level sub-domains. As a result, it lightens your load significantly while helping you cut down on costs involved with buying individual SSL certificates.

For those with a website with multiple sub-domains, instead of using individual SSL certificates, it's recommended to buy Wildcard SSL certificates as it helps reduce repetitive tasks like CSR generation and validation process; additionally, at CerteraSSL, you will get cheapest wildcard SSL Certificates compare to any other SSL provider.

Wildcard SSL Certificate

What is a Wildcard SSL Certificate?

An SSL/TLS Wildcard certificate is just a single certificate containing the wildcard symbol (*) in the domain name field. This enables the certificate to protect several subdomain names (hosts) linked to the same base domain.

For instance, a wildcard certificate for *.(domain).com might be used for www. (domain), mail. (domain), store. (domain), in addition to any other subdomain name in the (domain).com.

Additionally, using a wildcard SSL is cheaper than getting individual certificates for every subdomain.

Wildcard Certificate

How Does Wildcard Certificate Work?

All subdomain names are covered with a wildcard SSL certificate, minimizing the need for several certificates to secure your organization's internet traffic. For instance, the "*.google.com" wildcard certificate can be used to protect "www.google.com," "mail.google.com," and "calendar.google.com."

Wildcard certificates can be divided into two different categories:

Domain Validation (DV) SSL Certificates can be issued quickly, but you must verify your domain ownership.

Organization Validation (OV) SSL Certificates include the organization's information and are only used by registered businesses. To get permission, though, you must go through a review procedure.

All subdomains use a private key stored in a wildcard SSL certificate. A private key is generated when a certificate signing request (CSR) is sent during the certificate creation process. When installing the certificate, you must copy the private key to each server if many servers are being used.

What are the Benefits and Risks of Wildcard?

Benefits Includes:

For organizations seeking flexibility and security for many subdomains, SSL wildcard certificates can be beneficial. Wildcard certificates' primary benefits are:

Secure multiple subdomains:

Without installing a different certificate for every subdomain, a single wildcard SSL certificate can secure as many subdomains as you want.

Simple certificate management:

It is strenuous to deploy and manage individual SSL certificates to secure a growing number of public-facing domains, cloud workloads, and devices. The maintenance of certificates becomes simple using wildcard certificates.

Requires minimal cost:

A wildcard certificate is more expensive to issue than a standard SSL certificate, but it is still a more affordable alternative when compared to the overall cost of getting individual certificates for each of your subdomains.

Adaptable and quick implementations:

Wildcard certificates are the best option for building new sites on new subdomains that your current certificate can secure. You can save time and accelerate speed to market by not having to wait for the issuance of a new SSL certificate.

Risks Includes:

Acquiring Private Keys:

A wildcard certificate's private key can be exploited by a hacker, allowing them to pretend to be any domain.

Fake Certificates:

Attackers have a way of tricking a certificate authority (CA) into issuing a wildcard certificate for a fake organization. The attacker can create subdomains and phishing websites once they get the wildcard certificates for the bogus company.

Certificate Management:

A new certificate is needed for each sub-domain if the wildcard certificate is revoked.

Wildcard SSL Certificate Benefits

Encrypts Communication Encrypts Communication

Wildcard SSL certificate is a digital security certificate that helps encrypt communication between web browsers, domains, and sub-domains using robust encryption strength. It assures that information sent between client and server will remain secure using the latest encryption strength approved by the CA/B forum.

Site SealSite Seal

The certificate authority issues a wildcard SSL certificate with a dynamic site seal. It works as a trust badge that once anyone clicks the site seal, the visitor will get the company information along with the current date and time, which helps build the user's trust and confidence.

Unlimited Domain SecurityUnlimited Domain Security

Wildcard SSL certificates are designed specifically for securing websites that have multiple sub-domains. In addition, there's no limit to how many sub-domains you can secure. Hence, as mentioned above, you get the benefit of reducing the cost significantly while securing an unlimited number of sub-domains.

For example:

  • www.domain.com
  • mail.domain.com
  • user.domain.com
  • anything.domain.com

Easy Management Easy Management

One of the most significant issues faced with multiple SSL certificates is remembering renewal dates. And often, site owners miss the renewal date and get to know once the website starts showing the "Not Secure" warning.

However, if you purchase wildcard SSL certificate, you won't face such issues, and you'll only require managing one Wildcard SSL certificate. In addition, it secures your main domain and all the sub-domains, making it easier to remember only one renewal date, CSR generation, or the validation process.

WarrantyWarranty

Certificate Authorities know the importance of SSL security and believe in taking responsibility for the same. Henceforth, as an assurance, it provides you with a warranty amount to ensure you won't face any SSL-related issue that costs you any money or damages your reputation.

RefundRefund

Certificate Authorities offers its wildcard SSL certificate with 100% refund surety. So, if you want to cancel your Wildcard SSL certificate, you can do so. And, if you cancel your SSL certificate within 30 days of purchase, you'll get a 100% guaranteed refund.

Frequently Asked Questions

Have Questions? We're here to help.

What is a Wildcard SSL Certificate?

Wildcard SSL certificate is the digital security certificate offered by certificate authorities that provides HTTPS security for your main website and an unlimited number of first-level sub-domains.

In other words, a Wildcard SSL certificate is a single SSL certificate with a wildcard character (*) within the domain field that allows your SSL certificate to secure multiple sub-domain names (hosts) that are associated with one base domain.

How to Generate CSR for Wildcard SSL Certificate?

Purchasing and installing a Wildcard SSL certificate isn't different from a standard single-domain SSL certificate. The main difference is that once you begin creating CSR (Certificate Signing Request), you'll have to put an asterisk at the sub-domain level. For example:

*.examplewebsite.com

It'll signify that you're looking to encrypt sub-domains, and it's within the first level of your URL. Similarly, you can generate CSR using the free to use CSR generator tool, or else you can even use the OpenSSL command.

Where to Buy a Wildcard SSL Certificate?

CA/B forum member Certificate Authorities are allowed to issue the Wildcard SSL certificate to public domains; Comodo, Sectigo and Certera are one of these CA offering Wildcard SSL. You can buy the SSL directly through their official website or else visit SSL providers like Certera.com to get the pricing benefits.

How does a wildcard SSL certificate work?

While generating the CSR for Wildcard SSL Certificate make sure to use the wildcard character (*) in the domain name for which SSL is issued. This will allow the certificate to be used for any subdomain that is created under the main domain.

How long does it take to issue a wildcard SSL certificate?

The process of issuing a wildcard SSL certificate typically takes from minutes to 3 days depending on the certificate authority (CA) and the type of validation type.

  • If you have purchased a DV Wildcard SSL, it takes few minutes to get issued.
  • If you have purchased a OV Wildcard SSL, it takes up to 3 days as the CA needs to verify both domain and organization.
What is a Wildcard SSL Certificate Used for?

A wildcard SSL certificate secures a domain and its unlimited subdomains with a single certificate. It ensures the security and integrity of any organization by safeguarding the customers' sensitive information and building long-lasting trust.

What is the Difference between SSL Certificate and Wildcard SSL Certificate?

The main difference between an SSL certificate and a wildcard SSL certificate is that the former secures only a single domain. In contrast, the latter can secure multiple subdomains of a domain.

Is Wildcard SSL Free?

Wildcard SSL certificates are not typically accessible. They usually involve a cost, as they provide enhanced functionality compared to regular SSL certificates. But at Certera.com, you can get best wildcard SSL certs at cheapest rate stars at $10.99/Year.

What are the Risks of Wildcard SSL?

The risks of wildcard SSL certificates include potential security vulnerabilities if the private key is compromised, as it can be used to secure multiple subdomains. Additionally, if one subdomain is compromised, all other subdomains may be at risk.

How do I know if my SSL is Wildcard?

Follow the steps mentioned below to confirm whether your SSL is a Wildcard or not:

  • Click on the Padlock icon.
  • From the list, expand the Connection is secure option by clicking on it.
  • From the list, click the Certificate is valid option.
  • The SSL certificate will appear.
  • In the General tab, under the Issued to section, verify whether the Common Name (CN) contains a wildcard character (* ) in front of your domain name or not. If it's there, then it is a Wildcard SSL certificate.
Can a Wildcard Certificate Protects Multiple Domains?

No! Wildcard SSL certificates can't secure multiple domains. These SSL certs can only secure a single domain and unlimited subdomains pertaining to the same base domain. For example, if you request your certificate for *ssl.com, you can secure best.ssl.com, cheap.ssl.com, etc.

Can I use a Wildcard SSL Certificate on Multiple Servers?

Yes! You can use a Wildcard SSL certificate on multiple servers. To install a wildcard certificate on additional servers, copy the private key from the original server and paste it to each additional server. Keep the private key secure by encrypting it and password-protecting the file, as if it gets compromised, the SSL certificate will become worthless.
