Nowadays, Websites have become complex. With numerous pages, sites also have multiple sub-domains for various purposes (blog, login, products). Buying multiple SSL certificates for every single subdomain is costly and time-consuming. This is where Wildcard SSL certificates come in handy.
Wildcard SSL Certificate Definition
A Wildcard SSL certificate secures one main domain and all its first-level subdomains with just one certificate. For example, a certificate issued for *.yourdomain.com will secure www.yourdomain.com, blog.yourdomain.com, mail.yourdomain.com, and so on.
