Extended Validation (EV) Multi-Domain Certificates are SSL (Secure Socket Layer) certificates that offer the highest degree of authentication and protection using one certificate for many domains and subdomains.

To ensure this, they require more evaluation and documentation checks for applicant websites than other certificate types.

Trustify EV SSL certificates include a manual validation step to confirm:

• The legal, physical, and operational existence of the entity
• That the entity has properly authorized the issuance of the certificate
• That the entity has exclusive right to use the domain specified
• The identity of the entity matches official records
