DigiCert EV Multi-Domain SSL Certificates

Unified Communications/SAN Certificates with the Green Address Bar

EV Multi-Domain Certificates

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

Extended Validation (EV) multi-domain SSL certificates combine Unified Communications (UC) Certificates/Subject
Alternative Name (SAN) Certificate with the ‘green bar of assurance’ & ‘green padlock’ to boost user confidence and enhance security. EV SSL multi-domain certificates use Subject Alternative Names to secure up to 25 domains, sites and subdomains with one certificate. In the basic plan for EV multi-domain SSL Certifications, three
domains are included and additional domains can be purchased separately.

For example, with an EV multi-domain certificate you can secure

  • www.example.com

  • www.example2.com

  • www.example3.com

  • mail.example.net

  • dev.example2.com

EV Multi-Domain certificates are perfect for Exchange and OCS environments where there is a need to secure multiple names across various domains while certificates with extended validation use the highest level of authentication designed specifically with the intention to boost customer confidence in e-commerce sites. Every certificate application goes through a stringent process of evaluation supported by documentation checks to confirm the ownership and legitimacy of websites.

Green Means Trust 

ssl multi domain

DigiCert adheres to a set of criteria strictly defined by the CA/Browser Forum when validating a website for an EV certificate. In fact, DigiCert is a founding member of the CA/Browser Forum and has contributed to the development of the extended validation certificate 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?





Upon purchase of an EV certificate, DigiCert’s validation specialists would contact the requesting organization to confirm their request of the certificate and that the person applying is authorized to receive the certificate on behalf of the organization. This is part of the validation process involving the human touch to prevent fraudulent or phishing activities (SSL phishing).

  • Green in the address bar (green bar or issuance name, see below)
  • 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

3 SAN names are automatically provided in each EV multi-domain certificate. A maximum of 25 names can be used on every certificate and these additional names are purchased separately. Having multiple names can build different configurations according to the needs and environment. With an EV multi-domain certificate, you can secure your domain, a subdomain and even a completely different domain.


Cutting-Edge Data Encryption


Using DigiCert’s 2048-bit root certificates with 256-bit symmetric and asymmetric encryption is one of the best ways to protect your website from unwanted intrusion. DigiCert certificates adopt a hybrid cryptosystem supporting both SHA-1 and SHA-2 algorithms to provide the most secure encryption available.
