Advantages Offered By Wildcard Certificate

A wildcard SSL certificate, also referred to as a certificate is specifically designed to provide encryption, for multiple subdomains within a single domain. With one certificate you can conveniently protect an unlimited number of subdomains reducing the time and effort required for certificate management.

To better understand the advantages offered by a certificate lets delve into the structure of SSL certificates. Normally if you have subdomains that require security measures you would have to obtain and install SSL certificates for each individual subdomain. This process can be tedious, costly and complex—particularly when dealing with a number of subdomains.

Fortunately with a certificate at your disposal you can secure all your subdomains with one certificate. The asterisk (*) in the certificate acts as a placeholder for any subdomain. For instance, if you have a certificate, for “* ” it will effectively secure “ ” “,” “,” and so on. Wildcard certificates are an option, for businesses or organizations that have a variety of subdomains due to their versatility.

  • Simplicity

One of the benefits of certificates is their simplicity in certificate management. Of dealing with certificates you only need to handle one certificate reducing the chances of overlooking or forgetting to renew any individual certificate. This not saves time. Also guarantees uninterrupted security for your entire domain and all its subdomains.

  • Cost savings

Cost savings are another advantage provided by certificates. Since you only need to purchase and maintain one certificate it is more cost effective compared to buying certificates for each subdomain. Additionally, many certificate authorities offer bulk pricing options for certificates, which further lowers costs for businesses with subdomains.

  • Encryption and security

Furthermore, wildcard certificates offer the level of encryption and security, as SSL certificates. They employ the strong encryption algorithms to safeguard data transmitted between the server and the client ensuring that sensitive information remains confidential.
This means that all the different sections of your website including any subdomains will have the level of security. This is news because it gives your visitors a sense of assurance when they interact with your website.

What are some of the limitations? 

However, it’s important to understand that wildcard certificate do have some limitations. They can only secure subdomains at one level. For instance, if you have a certificate, for “* ” it will secure “” and “,” but not “” So if you need to secure subdomains at levels you would need to consider purchasing a multi-level or SAN (Subject Alternative Name) certificate.

Also there is a drawback with certificates. If a wildcard certificate gets compromised or misused all the subdomains covered by that certificate could be affected. That’s why it’s crucial to choose a certificate authority and regularly monitor the security of your certificate to minimize any risks.


In conclusion using a certificate is a solution, for businesses and organizations that manage multiple subdomains. It simplifies the management of certificates reduces costs and provides a level of security as SSL certificates.
However it’s crucial to grasp the constraints and potential hazards linked with certificates in order to guarantee an protected deployment.
