Websites & Email · Multi-domain (SAN) · several separate domains
Put a list of unrelated domains on one certificate
One certificate carrying a list of names — up to 250 of them, on completely unrelated domains. It is what a wildcard cannot do, it is what Exchange and unified communications need, and it replaces a spreadsheet of renewal dates with one.
- Up to 250 hostnames
- Unrelated domains welcome
- The Exchange and UCC answer
- One renewal date
- 33 certificates, from $114
What one missing hostname does
One name left off the list. On Exchange this is the certificate prompt every member of staff dismisses every morning, until somebody works out which hostname is missing.
On the certificate alongside mail., smtp., imap., webmail. and your web names — one file, one install, one renewal date.
- The authority issues it, not usComodo, Sectigo, GeoTrust, Thawte, Certum and RapidSSL sign your certificate. Identical file, identical trust, lower price.
- 10 days to change your mindA full refund or a swap to a different certificate. SSL certificates only. Read the policy.
- Wrong one? We will say so firstSend us the hostnames before you buy and we will name the cheapest certificate that covers them — including when that is not the one you were about to order.
- Lowest price guaranteeFind the same certificate cheaper anywhere and we match it.
- Free unlimited reissuesChange a hostname or move host mid-term at no cost.
- Unlimited serversOne file on the load balancer, the app servers and staging.
- Free installation supportcPanel, IIS, Nginx, load balancers and appliances.
A list of names, not a pattern
Each hostname is written into the certificate explicitly, which is why a multi-domain certificate can span domains a wildcard cannot touch. The flip side is that a name nobody listed is not covered — though adding one is a free reissue rather than a new purchase.

Is this the right one for you?
The most expensive mistake on this site is buying the wrong shape and finding out at install time. Two lists, and the second one is a route out rather than a dead end.
Buy this if
- You run two or more registered domains — a .com and a .co.uk, or several brands
- You are securing Exchange or Microsoft 365 hybrid and need mail., autodiscover., webmail. on one file
- A firewall, load balancer or appliance answers on a handful of unrelated names
- You want one purchase order and one renewal date instead of five
- The hostname list is known and reasonably stable
Look at this instead if
- Every name sits under one domainWildcard SSL
- You need every subdomain of several domainsMulti-domain wildcard
- There is only one site and one nameSingle-domain SSL
- You want the company name inside as wellOrganisation validated
Where this shape earns its price
Buying one of these is almost always a decision about administration rather than about encryption. That is a good reason, and it is worth being explicit about it.
- Mail servers answer on more names than anyone expectsmail., smtp., imap., webmail. and, on Exchange, autodiscover. Miss one and Outlook prompts every user every morning until somebody works out why. This is the single most common reason people end up here.
- A wildcard cannot cross a registered domainIf your estate is acme.com and acme.co.uk, no wildcard will cover both. Each name goes on the list explicitly, which is exactly what this shape is for.
- Consolidation is the real savingFive certificates means five renewals, five installs and five chances to miss one. One file on one date, deployed once, is worth more than the difference in sticker price to anybody who has been on the wrong end of a lapse.
- Extra names are a free reissue, not a new purchaseEvery certificate here reissues free for the whole term. Adding a hostname you forgot costs you a redeploy and nothing else, provided you bought enough slots.

Prices are for one year. Most of these can be bought for two, which is the longest term the industry rules allow to be sold — the saving is shown on the product page.
How to choose between them
Once you are on the right page the remaining decision is small, and it comes down to three things in this order.
How many names you actually need
Count them before you buy, including the ones you forget: the bare domain, the www, every mail hostname, autodiscover, and anything a load balancer answers on. Certificates here include between three and five and sell more in blocks.
Whether the company name has to be in it
The domain validated ones issue in minutes with no documents. The organisation validated ones take one to three working days, involve a phone call, and put your registered company name inside where an auditor can read it.
What one extra name costs
The per-name price varies more than the headline does, and on an estate that grows it matters more. Ask us for the marginal figure on any certificate here before you commit — it is often the deciding number.
Questions we get asked before people order
What is a SAN, and is a UCC certificate the same thing?
SAN stands for Subject Alternative Name — the field in the certificate that holds the extra hostnames. UCC, or Unified Communications Certificate, is Microsoft’s name for the same technology sold with Exchange and Skype for Business in mind. Technically they are the same certificate; the UCC products simply bundle more names by default.
Can I add a hostname after it is issued?
Yes, as long as you have a free slot. Reissues are free and unlimited for the whole term on every certificate here, so you regenerate the certificate with the new name on it and redeploy. If you are out of slots, extra names can be bought and added at any time.
Do the domains have to be related, or owned by the same company?
They do not have to be related, but you do have to prove control of every one of them — and on organisation validated certificates, that the vetted company is entitled to use them. Practically that means an email or DNS record per domain at the domain validated level.
Does it cover subdomains of the names on it?
No. Each entry is a literal hostname, so listing acme.com does not cover shop.acme.com. You either list the subdomain as another name, or you look at a multi-domain wildcard, which lets you put *.acme.com on the list instead.
How many names can one certificate hold?
Up to 250 on most of the certificates here, and the listing shows both the number included and the maximum for each. In practice very few estates exceed twenty, and the ones that do are usually better served by a multi-domain wildcard.
Will one certificate work across several servers?
Yes. Everything on this page is licensed for unlimited servers, which is exactly what you want when the same hostname list is served by a load balancer and two application servers.
The other ways to cover a website
Two of these answer what the certificate has to cover and three answer how much you have to prove about who you are. Every one of them is a full price list like this page.
- Single-domain SSL One name, plus its www — issued in minutes
- Wildcard SSL *.yourdomain.com — unlimited subdomains
- Multi-domain (SAN) SSL Up to 250 unrelated domains on one certificate
- Multi-domain wildcard Several domains, each with all its subdomains
- Organisation validated (OV) Your registered company name inside the certificate
- Extended validation (EV) Legal, physical and operational checks
Send us the hostname list and we will price it
A line about what the site does and which names it answers on is enough. We come back with the cheapest certificate that genuinely covers it — including when that is one certificate instead of the four you were about to buy. No obligation and no sales call.
