As we are aware organizations deploy Secure Sockets Layer (SSL) certificate for their domains to ensure data protection and to restore faith in consumers’ minds. SSL is a standard security technology that enables organizations to establish an encrypted link between a web server and a client.
This makes it impossible for attackers to intercept the data flow (between a web server and a client) and use the information. SSL is an absolute necessity for e-commerce or for organizations that collect sensitive data.
The benefits of an SSL Certificate are limitless however this can be a daunting task for a new company that decides to have multiple subdomains of a single domain. Here’s where a Wildcard SSL Certificate is proving to be a boon for such websites saving them time and costs.
Wildcard SSL Certificate is a private key certificate that can secure all related (unlimited number of) first-level subdomains of the principal domain, thus eliminating the need of buying an SSL certification for each of them. It lets you specify additional hostnames such as email addresses, IP addresses, URLs, DNS names, etc. to be protected by a single certificate. In a nutshell, using a Wildcard SSL Certificate you can secure unlimited sub-domains on a single domain name.
For Example:
A single wildcard certificate for https://*.https.in will secure all these subdomains on the https://*.https.in domain:

Further, you will have to repeat the exercise at every renewal, thus blocking a lot of your resources.
Customers can get a Wildcard SSL certificate within two days, as the certificate doesn’t follow long verification processes like extended validation (EV) certificate. It takes a few minutes for issuance if CA follows the domain verification method to verify the business.
Wildcard SSL Certificate provides your website with a Trust indicator known as “Padlock”. This padlock indicates that the website is secure because of SSL encryption. Customers will put trust on your website as the site is secure with a high-grade SSL Certificate – “Wildcard SSL Certificate”.

Finally, Wildcard SSL Certificates is the best Certificate to choose as it not only saves costs while securing unlimited sub-domains, it also makes things easier to manage.
Yes, Wildcard Certificate will help you in securing n number of sub-domains of a domain at a reasonable cost.
According to the OpenSRS blog, a wildcard certificate allows for unlimited subdomains to be protected with a single certificate.
For example, a Wildcard certificate for opensrs.com will secure all these sub-domains: mail.opensrs.com, ftp.opensrs.com, and many more sub-domains.
A SAN certificate allows for multiple domain names to be protected with a single certificate.
For example, you could get a certificate for opensrs.com. Simultaneously you can add more SAN values to have the same certificate protect opensrs.org, opensrs.net, and even tucows.com.
