MULTI-DOMAIN SSL

Multi-domain SSL certificates allow a single certificate to secure multiple domains, including subdomains of a single main domain name or entirely different domain names. This type of digital certificate is also commonly referred to as a UCC SSL (Unified Communications Certificate) or a SAN SSL (Subject Alternative Names).

They work well for businesses with multiple websites and/or servers to secure. They’re often used for Microsoft Exchange servers and Office communications servers and will operate as multi-domain SSL certificates if the number of servers is more than three. Nisse-SSL® offers Domain Validation, Organization Validation, and Extended Validation options.

Validation

Requirements

The time required to validate and issue a Multi-Domain SSL depends on the validation option you choose. Multi-domain DV certificates are typically issued within minutes, while OV SSL and EV SSL certificates can take 1-5 days. Nisse aims to make the process as easy and hassle-free as possible—these steps and tips will help guide you through the process.

Domain Validated SSL certificates are the most basic and easiest to validate using a single step to verify the person or organization who owns the registered domain(s).

To complete the validation, the domain owner must prove that they own the fully qualified domain name or names that were submitted with the order.

The easiest and preferred method is completing the verification with email-based authentication. Using this preferred method, we will send an email to the WHOIS registrar email address asking you to verify that you purchased a DV certificate. Once you positively respond to our email, the requirement is considered satisfied and the certificate can be issued within minutes of a completed order.

As an alternative to the WHOIS registered email, we can send the authentication email to one of five pre-approved email addresses associated with the website domains. The five pre-approved addresses are:

If the email Domain Validation does not work for your particular situation, there are alternative methods.

  • File-Based Authentication – we will provide you with a text file that you will need to upload to the root directory of your website. We will then verify your websites via HTTP or HTTPS.
  • CNAME-Based Authentication – we will provide you with two unique hash values (these are MD5 and SHA1). You, in turn, must enter them in your CNAME DNS record.

Organization-validated SSL certificates for multiple domains require more validation than Domain-validated ones and provide more trust. With an OV certificate, we confirm the business associated with the domain names is registered and legitimate by checking details such as the company name, location, address, and incorporation or registration information. This makes the certificate a more suitable option for public-facing websites that represent companies or organizations. OV’s are usually used by corporations, governments and other entities that want to provide an extra layer of confidence to their website visitors. Organization Validation requirements for an organization include:

  • Domain Ownership/Authentication
  • Organization Authentication
  • Locality Presence
  • Telephone Verification (Organization phone number found on an online database
  • Final Verification phone call

For legitimate organizations, this process goes smoothly and quickly. Remember, an OV certificate differentiates legitimate businesses from the pretenders—including scammers and hackers.

  • An OV SSL certificate for an individual requires the identity and address to be validated on the certificate. Individual identity is verified by the applicant providing one of the following documents:

    • Legible copy of a government-issued photo ID such as a valid driver’s license, passport, military ID, or National ID
    • Copy of a recent major utility bill (i.e. power bill, water bill, etc.)
    • Copy of a bank or credit card statement
  • The Extended Validation certificate has very strict industry guidelines that our validation specialists make as simple as possible with minimal action required from you. This level of security is recommended for sites that obtain personal information from users, such as eCommerce websites.

    The validation of your organization can be completed using 1 of 3 methods:

    • DCV email
    • CNAME
    • HTTP(S) challenge

    Anticipate a telephone call to the main business phone number listed on the subscriber agreement to verify the signature, authority to sign and signer’s title. If any additional actions are required a validation specialist will reach out to you via email. The telephone call to verify the authenticity of the order and signer listed on subscriber agreement can not be made to a direct phone number or cell phone unless the number can be validated.

    Tips When Validating

    • Sole proprietorship / sole trader and some partnerships require a principal individual in the organization to be verified.
    • All EV certificates must have the legal name. If a tradename/DBA is verified, the certificate will be listed with the tradename and legal name.
    • In the case of a sole trader the legal name is the owner/principal name.
    • No certificate can be issued to the tradename/DBA name only.
    • Use the address where the organization conducts business. Do not use PO Box, Care of, mail stop/forwarding, virtual office or a registered agent address.
    • If the Validation Specialist is not able to verify your organization, you will be contacted with options on how to resolve any outstanding issues.

Yes. Unlike a Single SSL certificate, a Multi-domain Certificate, also called a UCC or SAN certificate, can secure hundreds of websites and servers. This makes keeping up with the certificate lifecycle status for each domain name especially easy.

A multi-domain certificate can secure multiple primary domains while a wildcard certificate secures one primary domain and related subdomains off of that top-level domain.

Nisse-SSL offers multiple plan options, depending on your needs, starting at $249 for a Multi-domain DV SSL, $449 for an OV, and $599 for EV.

Multi-year plans provide instant savings and consistent coverage in a simplified, long-term solution. While you will have to reissue your certificate each year per industry standards, you’re guaranteed the lowest price today, and locked in with coverage for multiple years.

Alex Byrne

I validated and installed the SSL/TLS cert in about 5 minutes. Overall I give them a thumbs up

Jordan

The SSL certificate worked good as I expected but the service I was given was outstanding. TomZ one of the nisse-ssl.com representatives guided me for about an hour or more and led me to having a fully secured site.

Javier

It took us about 30 minutes to get SSL and now we are good for 5 years
