Increase Conversion Rates and Strengthen Online Trust with Green-Bar Assurance

Protect your most valuable assets, your customers, and your brand by guarding against phishing scams and online fraud

Extended Validation (EV) Multi-Domain Certificates give you the flexibility of a Unified Communications (UC) Certificate with the green-bar assurance of Extended Validation. EV Multi-Domain Certificates use Subject Alternative Names to secure multiple sites (e.g. fully qualified domain names) with one certificate. Three SANs are included in the base price of the EV Multi-Domain Certificate. However, you can buy additional names at any time as long as the certificate is valid.

With an EV Multi-Domain Certificate, you can secure:


This makes EV Multi-Domain Certificates perfect for Exchange/OCS environments or any environment where you need to secure multiple names across different domains. Certificates with Extended Validation also use the highest level of authentication and were specifically created to boost customer confidence.

Green Means TRUST

When validating a website for an EV Multi-Domain Certificate, DigiCert complies with a process that is strictly defined by the CA/Browser Forum. In fact, DigiCert is a founding member of the CA/Browser Forum and assisted in developing the extended validation certificate and validation process. This process includes:

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

What does EV look like in Internet Explorer, Firefox, Chrome, Opera, and Safari?

As part of this process, one of our validation specialists contacts the requesting organization to confirm that they requested the certificate and that the applicant is authorized to receive the certificate on behalf of the organization. By maintaining this human element in the validation process, it is very likely that fraudulent or phishing-related activity will be detected.

To let users know that a website has an EV Certificate, browsers show more visual cues for sites secured with EV Certificates. EV Certificates include the following visual benefits:

  • Green in the address bar (green bar or issuance name, see above)
  • Website owner's company name in the address bar
  • https:// at the beginning of the domain name
  • Padlock in the address bar
  • Organization information in the certificate details

EV Multi-Domain Certificate Configurations

Each EV Multi-Domain Certificate includes 3 SAN name spots automatically. You can purchase additional names at any time during the lifetime of the certificate. With these names, you can have many different configurations depending on your environment and your needs.
