Explanation

You would need three wildcard certificates: *. east.company.com *. central.company.com *. west.company.com The common domain in each of the domains is company.com. However, a wildcard covers only one level of subdomain. For example: *. company.com will cover "<anything>.company.com" but it won't cover "<anything>.<anything>.company.com". You can only have one wildcard in a domain. For example: .company.com. You cannot have ..company.com. Only the leftmost wildcard () is counted.
