You have several domains: main business site, landing pages, old versions, language variants. Buying SSL for each is expensive and hard to manage. SAN certificates let you combine up to 100 domains in one certificate. Ideal for corporate and large projects.
What SAN is and how it works
SAN is a field inside the certificate that lists multiple domain names. Traditional certificates are issued for one domain (Common Name), but with SAN one certificate covers 5, 10, 50 or 100 domains. Browsers check the list inside the certificate when visiting a site and show the lock if the current domain is listed.
SAN vs Wildcard
Wildcard works as *.sayt.uz — covers any subdomain automatically. But it doesn't work on another domain like domen.uz. SAN is the opposite — covers different domains but each must be listed. Strongest option is Wildcard SAN: different domains plus their subdomains together.
When SAN is needed
A company has 5-10 sites: corporate, blog, store, sub-brands, locale variants. Individual SSL costs 100 dollars or more, SAN runs 50-150 dollars. Management is easier: one certificate, one expiry. SaaS platforms and corporate portals can't function without SAN.
Adding and removing domains
Initial domain list is specified when ordering SAN. Later additions go through reissue — usually free but takes time. Validation re-runs for all new domains. Some providers cap the maximum: 5, 25, 100 depending on the plan.
Validation types
SAN comes in DV, OV and EV flavors. DV (Domain Validation) is simplest, 15-30 minutes. OV (Organization Validation) checks company documents, 1-3 days. EV (Extended Validation) is deep verification, 5-10 days, company name in browser bar. DV is enough for most.
Sayt.uz practice
Sayt.uz offers SAN SSL ordering. Packages for 3-5 domains from 450,000 UZS, corporate plans for 10-25 domains from 1,200,000 UZS. Auto-install, yearly reminders, renewal docs ready. For multi-site clients this is 3-5 times cheaper than separate certificates.
