A wildcard certificate is one type of secure certificate that you can use on your website. But do you what it is all about and some of the benefits it offers? Here, we want to reveal something so stay in touch
What is a wildcard certificate?
A wildcard certificate is a kind of SSL/TLS certificate that allows you to secure subdomains under a single certificate. Of obtaining and managing certificates, for each subdomain you can use a wildcard certificate to cover all the subdomains together.
In a certificate the asterisk (*) symbol acts as a character representing any number of characters in the domain name. For instance, if you have a certificate for *.example.com it will secure any subdomain you create under example.com, like blog.example.com or store.example.com.
What are the advantages of Comodo certificates?
Using a certificate offers advantages.
- Simplicity
Firstly, it simplifies the management of SSL/TLS certificates for your website. Of dealing with certificates and their individual renewals you only need to handle one wildcard certificate. This saves both time and effort particularly if you have subdomains to secure.
- Cost saving
Another benefit is that using certificates can lead to cost savings.
While wildcard certificates may be a bit pricier, than SSL/TLS certificates the overall cost is usually favorable considering the number of subdomains you can protect with one wildcard certificate. If you have subdomains using a certificate can be a more cost effective solution.
- Scalability
Wildcard certificates also offer scalability for needs. If you plan on adding subdomains to your website on there’s no need to buy additional certificates. You can simply utilize your existing certificate to secure the subdomains. This flexibility is especially beneficial for websites that frequently change or expand.
It’s worth noting that while wildcard certificates cover a number of subdomains they don’t extend to levels of subdomains. For instance if you have a certificate, for *.example.com it will secure blog.example.com but not www.blog.example.com.
If you need to secure levels of subdomains you have two options;. Obtain a separate wildcard certificate or choose a different type of SSL/TLS certificate, like a Unified Communications Certificate (UCC) or a Multi Domain Certificate.
When using a wildcard certificate it’s crucial to install and configure it correctly to maximize security. Wildcard certificates encrypt the data transmitted between user’s browsers and your website safeguarding information such as login credentials, credit card details and personal data. Additionally these certificates authenticate your website giving visitors reassurance that they are visiting an secure site.
However it’s important to bear in mind that a wildcard certificate applies to all subdomains under the domain. This means that if one subdomain is compromised or hacked it has the potential to affect all subdomains covered by the certificate. Therefore implementing security measures like updates and patches strong passwords and firewall protection is essential to ensure the overall security of your website.
Conclusion
In conclusion using a certificate is a cost effective solution, for securing multiple subdomains within a domain. Simplifying the management of SSL/TLS certificates ensuring scalability, for expansions and saving time and cost are factors to consider. However, it is crucial to keep in mind the limitations and take security measures to safeguard your website and its users. By utilizing certificates, you can enhance the browsing experience, with enhanced security and establish trust with your visitors.
