Assurance & Authentication

The InstantSSL Premium Wildcard is the most assurance you can provide with a Wildcard SSL certificate—there is no Wildcard EV option. For all intents and purposes, this should be sufficient for most needs. Customers and visitors can still see verified business information by clicking on the certificate details. If you need the highest level of validation on your subdomains, we recommend an EV Multi-Domain certificate.
