250 SANs

Sectigo Multi-Domain SSL certificates can handle up to 250 different domains, sub-domains and IPs on a single certificate. This makes managing certificates a breeze. Here’s how it works: when you fill out your Certificate Signing Request, you are asked to insert the domain you’re encrypting in the FQDN field. With a Multi-Domain certificate you also have the option to list additional websites in the SAN or Subject Alternative Name fields.

How do I get SANs?

Most Sectigo SSL certificates come standard with 2-4 SANs, after that you have to buy them individually. This is still more practical than springing for individual certificates, both from a cost perspective and from a certificate management one.

Whatever you need it to. Sectigo Multi-Domain SSL certificates are incredibly versatile. Here are some examples of sites you could secure with a Multi-Domain certificates.

  • mail.domain-one.com
  • domain-two.com
  • ftp.domain-two.com
  • website-one.net

Run Multiple Services

  • Outlook Anywhere
  • SMTP
  • AutoDiscovery
  • Active Sync

Multi-Domain EV SSL

One of the biggest advantages of the Multi-Domain certificate is that it’s available at the Extended Validation level. Browsers would never trust an EV Wildcard, owing to the danger of sub-domains. But with Multi-Domain, since each item listed is a known quantity (as opposed to blindly encrypting at the first sub-domain level of the URL) EV is possible.

Assert Identity

Make sure that no matter which one of your websites your customers are using—they know who’s running it. Assert your identity across every domain and sub-domain.

Align your Brand

When people see an EV Name Badge, they make certain assumptions about the company that’s behind it. You’ll be keeping good company when your visitors see your name badge and associate you with some of the world’s top companies.

Multi-Domain SSL FAQ

Q. Why choose Multi-Domain SSL?

A. Multi-Domain SSL certificates gives you the flexibility to secure up to 250 different domains, sub-domains and IPs, while also reducing the burdens of managing individual certificates for each.

Q. Multi-Domain vs. Wildcard SSL: what’s the difference?

A. A Wildcard certificate only secures one domain and an unlimited number of accompanying sub-domains. A multi-domain SSL certificate secures up to 250 different domains, sub-domains and IPs with a single certificate. So both the maximum (unlimited vs. 250) and the functionality are different.

Q. What is a Multi-Domain Wildcard SSL certificate?

A. A Multi-Domain Wildcard can function as both a Wildcard and a Multi-Domain certificate. You can place an asterisk at the sub-domain level you’re trying to encrypt in the SAN fields of the CSR. This lets it encrypt up to 250 domains and all of their accompanying sub-domains.

Q. What's the Difference between UCC and Multi-Domain certs?

A. Originally UCCs were designed to work specifically with MS Exchange and Office Communications servers. Nowadays you can use other certificates on those servers, too.
