The case is simple:
If there are multiple sub-domains to secure, then a BlackCert *Wildcard SSL Certificate purchase will save you hundreds or thousands compared to the cost of buying individual SSL certificates. And you'll only have one certificate to manage.
Rest assured you are using the best technology the industry has to offer. BlackCert *Wildcard SSL Certificates have all the security features, compatibility and warranty of our single domain certificates.
Pricing structure from other providers can spike the price of your certificate usage for each and every license. We will not double, triple, or raise that price by one cent. Every certificate comes with unlimited server licensing included in the price - which means you are free to install it on as many physical servers as you need to.
