Large enterprises with multiple domains must consider multiple sub-domains for the parent website. It improves search engine rankings and allows you to target specific market segments for increased visibility. However, the security of your subdomains is just as critical for businesses. Installing a Secure Sockets Layer (SSL) certificate becomes vital at this point. It is a feature that ensures your data is encrypted and supplied via an HTTPS connection. But choosing the right SSL certificate is not an easy decision, especially since so many options are available. But if you have multiple subdomains, installing the best Wildcard SSL Certificate is the wisest option to choose as it secures all your subdomains with a single certificate rather than installing a separate certificate for every individual domain.
In this post, we will learn what Wildcard SSL certificate is, why Wildcard SSL Certificate is necessary and how to install it. Let’s Begin!
What is a Wildcard SSL Certificate?
A Wildcard SSL certificate allows the security of multiple subdomains with a single certificate making it a cost-effective proposition for businesses. It works for all subdomains that have the base domain name. For example, if your domain name is “ourwebsite.com,” the Wildcard SSL certificate will also protect subdomains like “newourwebsite.com” or “freshourwebsite.com” etc.
All Wildcard SSL certificates come with an asterisk (*) sign before the domain name interprets all the strings of characters. It can be used for all the variations of ‘www’ and non-‘www’ domain names. All Wildcard SSL certificates encrypt data through a specific set of keys (public and private key) in a single name certificate. While the public key is usually stored in the digital format of the certificate, the private key is stored on your server. The private key in a wildcard certificate can be copied and uploaded to as many servers as you want.
When to use a Wildcard SSL Certificate
A single-name SSL certificate works well if you want to add just one subdomain. But one wildcard SSL certificate can secure multiple subdomains; therefore, a Wildcard SSL Certificate is essential for businesses with numerous web pages. Since all subdomains are kept secure under one wildcard SSL certificate, it saves time and money purchasing and installing single-name certificates on different subdomains.
Web developers who frequently utilise subdomains for testing or organisations who use subdomains for various web pages such as blogs, ecommerce, and so on can benefit from wildcard SSL certificates. Investing in a wildcard SSL certificate for future use is also an excellent idea. A wildcard SSL certificate will come in handy if your company grows and you need to expand your online presence by adding different subdomains.
