A multi-domain SAN SSL certificate is designed to protect multiple specified hostnames under one certificate. SAN stands for Subject Alternative Name, which is the certificate field used to list additional names the certificate should cover.
What can a SAN certificate protect?
Depending on the product, a SAN certificate can cover multiple domains or hostnames that are explicitly listed in the certificate. Review the current product limits before purchasing.
SAN SSL vs wildcard SSL
Wildcard SSL is most useful for many eligible subdomains under one base domain. SAN SSL is useful when you need to protect several different specified hostnames. The two products solve different coverage problems.
When does multi-domain SSL make sense?
- You operate multiple brands or websites.
- You want to manage several eligible hostnames with one certificate.
- A wildcard certificate cannot cover the unrelated domains you need.
What should you verify before buying?
- How many hostnames are supported.
- Which validation level applies.
- Whether installation/management is included.
- Billing and renewal terms.
