If you have a website that includes subdomain, Wildcard SSL is essential. Instead of purchasing certificates for every domain, you might as well purchase a Wildcard SSL for all subdomains, which can not only save your money but also facilitate management.
Wildcard SSL is a type of SSL certificate aiming at protecting every subdomain under your website, as long as these subdomains have same primary domain and are under one same server. Because the quantity of protected subdomains is not limited, unlimited subdomains can be protected.
Like other SSL certificates, Wildcard SSL provides standard 128-bit or 256-bit encryption, which can ensure the security of user's private information. SSl certificate can protect the security of data transmission, which means when users are going through online payment, logging in account or ordering E-mail, their information are definitely secure.
Wildcard SSL is suitable for the people who have website with subdomains, besides, because you can add any new subdomains, this certificate is very helpful for business expansion. Wildcard SSL has a lot of advantages. First, it is with high price performance and it can forever protect your primary domain and all subdomains with convenient management. Moreover, encrypted sign HTTPS will be displayed in browser if a website is using a primary domain or subdomain, proving that your whole website is protected.
Wildcard SSL can be installed in the server that authorizes your website. The widely accepted mainstream Web servers are Apache, Nginx, Microsoft IIS, NGINX and Tomcat. Actually there is no difference between installing a Wildcard SSL and a regular certificate, so there is no additional or rather difficult steps for installation, besides, CA will provide you with the installation instructions that are suit for you.
If you have more than one SSL certificate, updating overdue certificates may trouble you a lot. Sometimes, you don't even notice your overdue certificates, which is not good for managing certificates. But using a Wildcard SSL can avoid such a problem. You just need to take care of one certificate!
