Secure Hundreds of Domains and Subdomains With a Single Certificate

Multi-Domain SSL Certificates

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

Validation Requirements

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

DV Multi-Domain Validation

Domain Validated SSL certificates provide a straightforward validation process, requiring only a single step to confirm the ownership of the registered domain(s) by the individual or organization.

To complete the validation, the domain owner must prove to the certificate authority (CA) that they own the fully qualified domain name or names that were submitted with the order.

Preferred Validation Method

The preferred and most efficient verification method is email-based authentication. Using this 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.

Alternatively, we can send the authentication email to one of five pre-approved addresses associated with the website domain, instead of the WHOIS registered email. These approved addresses are:

Alternative Methods of Validation

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

File-Based Authentication – Sectigo 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 – Sectigo will provide you with two unique hash values (these are MD5 and SHA1). You, in turn, must enter them in your CNAME DNS record.

OV Multi-Domain Validation for an Organization

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.

OV Multi-Domain Validation for an Individual

An OV SSL certificate for an individual requires the identity and address to be validated on the certificate. Individual identity is verified by 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
Copy of a bank or credit card statement

EV Multi-Domain Validation

The Extended Validation SSL certificate adheres to strict industry guidelines, but our validation specialists simplify the process to require minimal action on your part. 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 a 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.

Sectigo offers multiple plan options, depending on your needs, starting at $279 for a 1-year Multi-domain DV SSL, $499 for an OV, and $649 for EV. The prices decrease with multi-year subscription options.

What are the Benefits of Purchasing a Multi-Year Certificate?
