SSL Wildcard Certificates

Published on May 25th, 2023

Are you seeking for a safe and effective solution to handle the SSL certificates on your website? SSL wildcard certificates are the answer!

These sophisticated features are intended to make securing many subdomains under one certificate as simple as possible, allowing you to safeguard your site without having to worry about individual certificates for each domain.

In this post, we’ll look at the best practices for deploying and managing SSL wildcard certificates, so you can keep your site secure while keeping things simple. So let’s get started!

Why Use SSL Wildcard Certificates?

SSL Wildcard Certificates are a form of SSL certificate that allows you to secure numerous subdomains with a single certificate. As a result, they are a practical and cost-effective solution for enterprises that want the security of multiple subdomains under the same domain name.

SSL Wildcard Certificates give security to your website by encrypting all communication between the server and the client. This implies that any sensitive information supplied through your website, such as login passwords or payment information, is safeguarded against prospective hackers or cyber criminals.

Furthermore, having an SSL Certificate on your website might improve your search engine optimization (SEO) rating.

Google considers HTTPS encryption to be a ranking signal and rewards sites that use it with higher SEO rankings.

You may assure optimum protection for visitors to those pages and their data while keeping strong SEO signals by using an SSL Wildcard Certificate across all subdomains.

How To Implement SSL Wildcard Certificate

Once you have secured an SSL wildcard certificate, you can easily implement it. Requesting the certificate from your provider is the first step in adopting it. Installing the certificate on your server should be simple after you obtain it.

Ensure that all subdomains are correctly set up and configured with their respective servers prior to installation. Then, for each domain name linked with the wildcard certificate, create a Certificate Signing Request (CSR).

Once you’ve created a CSR for each subdomain, send it to your vendor along with the SSL wildcard certificate order form. After finishing this process, you will receive an encrypted file containing your SSL wildcard’s private and public keys.

Simply install or import the SSL Wildcard Certificate into each individual web server inside each subdomain’s environment, where HTTPS traffic has to be safeguarded by HTTPS encryption to finish the SSL Wildcard Certificate deployment on your server.

After successfully implementing an SSL Wildcard Certification across all domains and servers associated, ensure that browsers can verify its authenticity as trusted by keeping accurate records and updates on expiration dates so they don’t expire prematurely, causing users to experience warning messages instead of secure connections when visiting sites hosted under this certification authority.

Managing And Monitoring SSL Wildcard Certificates

Monitoring SSL Wildcard Certificates

Managing and monitoring SSL wildcard certificates is a key activity for ensuring your website’s security. Maintaining track of each certificate’s expiration date, renewing it on time, and constantly assessing its functioning is critical.

One best practice for managing SSL wildcard certificates is to keep an inventory of all active certificates and their expiration dates. This will allow you to remain on top of when they need to be renewed and avoid service delays caused by expired certificates.

Furthermore, keeping an eye on your SSL wildcard certificates for any potential vulnerabilities or flaws is critical.

Regularly scanning your website with vulnerability scanners can assist in uncovering and addressing security vulnerabilities before they become a problem.

Another critical part of SSL wildcard certificate management is ensuring suitable access control measures are in place. Only authorized individuals should have access to the private keys used for these certificates since they include sensitive information that, if leaked, could jeopardize the security of your site.

You may maintain a high degree of security for your website while avoiding costly downtime or data breaches caused by certificate issues by successfully maintaining and monitoring SSL wildcard certificates.


In conclusion, SSL Wildcard certificates provide a cost-effective and efficient way to secure many subdomains inside a domain. However, it is critical to carefully deploy these certificates to provide optimum security and avoid any potential complications.

When establishing an SSL Wildcard certificate, remember to use a trustworthy CA and adhere to best practices such as producing unique private keys and keeping them secure. In addition, keep an eye on your certificates for expiration dates and any other problems that may emerge.

By adhering to these instructions and being conscientious about managing your SSL Wildcard certificates, you can help secure your website from potential security concerns while assuring your online presence’s smooth operation.
