What is the Difference Between Positive SSL and Wildcard SSL?
Positive SSL, Mutli-Domain SSL and Wildcard SSL certificates can be differentiated in terms of protection they offer to the domains and sub domains.
Positive SSL Certificate: Standard SSL certificate commonly called as positive SSL can secure only one main domain. It cannot be used to protect sub-domain(s) added under the main domain.
Wildcard SSL Certificate: Single certificate that secures a domain and multiple sub domains under it. However, it cannot protect more than one main domain.
Multi-Domain SSL Certificate: Renders protection to multiple main domains, up to 3 domains. But it cannot protect sub domains added under those main domains.
