The Comodo Positive Multi-Domain SSL certificate is the cheapest one of multi-domain certificates.The certificate includes by default 3 domains – 1 primary and 2 additional. The protection of the Positive Multi-Domain Wildcard does not automatically extend to the root domain domain.com and its subdomains (* .domain.com). To support both the primary domain and its subdomains, Wildcard support must be supplemented with additional domains (* .domain.com). For an additional fee, you can add up to 100 primary domains. It is an ideal solution for small commercial companies that need to secure several sites at once.
