Which certificate type can be used to secure multiple subdomains under the same domain?

A wildcard certificate is specifically designed to secure multiple subdomains within the same domain. For example, if you have a wildcard certificate for "*.example.com," it can secure "www.example.com," "mail.example.com," "store.example.com," and any other subdomain that fits the pattern. This capability to cover numerous subdomains with a single certificate simplifies management and reduces costs compared to acquiring individual certificates for each subdomain.

In the context of security solutions, using a wildcard certificate is an efficient way to streamline the process of securing subdomains without compromising on flexibility. Organizations that operate multiple subdomains can greatly benefit from this type of certificate by minimizing administrative overhead and ensuring a consistent level of security across their online presence.
