A GeoTrust wildcard DV (Domain Validated) certificate is a type of SSL/TLS certificate offered by GeoTrust, a leading Certificate Authority. This certificate allows you to secure your main domain and unlimited subdomains using a single certificate.
The "wildcard" aspect of the certificate means that it can secure any subdomain under your primary domain, making it highly flexible for websites with numerous subdomains. The "DV" designation indicates that the certificate undergoes domain validation. In this straightforward process, the certificate authority verifies that the applicant owns or controls the domain for which the certificate is issued.
