Multi-Domain OV


Product description

A Multi-Domain OV (Organization Validated) SSL certificate, also known as a SAN (Subject Alternative Name) certificate, allows you to secure multiple domain names (and sometimes subdomains) with a single certificate while providing a higher level of validation compared to Domain Validated (DV) certificates.

Here’s how Multi-Domain OV certificates work:

  1. Organization Validation (OV): Before issuing the certificate, the Certificate Authority (CA) conducts validation to verify the ownership of each domain listed in the certificate, as well as basic checks on the organization that owns the domains. This typically involves confirming the organization’s legal existence, physical address, and operational status for each domain included.
  2. Multiple Domain Support: Multi-Domain OV certificates have the capability to secure several domain names (and sometimes subdomains) under a single certificate. For example, you could secure “,” “,” and “” with a single Multi-Domain OV certificate.

Multi-Domain OV certificates are ideal for organizations that manage multiple domain names and want to ensure the security of all their online properties while providing a higher level of trust and credibility to their website visitors. They offer the flexibility to secure several domains under a single certificate, making them a cost-effective solution for organizations with diverse online infrastructures.

Unlike DV certificates, Multi-Domain OV certificates typically provide additional information about the organization behind the website, such as the organization’s name, in the certificate details. However, they may not display the organization’s name prominently in the browser’s address bar. Instead, they show a padlock icon to indicate a secure connection.
