Compare all SSL types

One certificate for every domain you run

A Multi-domain SSL certificate lists each domain you run on one install, so you replace separate certificates, staggered renewals and repeat installs with a single expiry date.

Separate domains on a single certificate
Your domains are listed as SAN entries on one certificate, so mybrand.com, mybrand.de and mybrand.shop are covered by a single install instead of one certificate each.
Fewer renewals, less to manage
One certificate means one renewal date and one install to track, instead of chasing a separate expiry for every domain you own.
Add domains as you grow
Add a domain to your certificate at any point in the term with a free reissue, whether you run a SaaS platform, several storefronts or a group of brands.
Strong encryption on every domain
Every domain on the certificate is protected with up to TLS 256-bit encryption, the same strength across your customer portals, admin panels and public sites.
Pick the trust level you need
Available with Domain Validation for fast issuance or Extended Validation for your verified company name in the certificate, so you match the trust level to what your buyers expect.
Installed and managed for you
We handle validation, installation and every reissue, so the certificate is live on your server without you touching a config file.

What we check before your certificate issues

The domain control and business identity checks that run before a Multi-domain SSL certificate is issued.

Domain Validation (DV) Multi-domain SSL certificates confirm technical control over each domain on the certificate. No business documents or identity checks are required, only proof that you manage the domains being secured.

Control of every domain is confirmed automatically, usually through a DNS record you add or an approved email address. Once that check passes, the certificate is issued within minutes.

We recommend DNS-based validation. It is the most reliable method, and it renews the most easily as certificate lifespans keep shortening.

Issuance timeframe
✔ Typically within minutes of successful validation
✔ No business checks, documents, or identity verification required

Extended Validation (EV) Multi-domain SSL certificates follow the strictest industry standards for identity and business verification. The requirements are strict by design, and our validation team guides you through each step.

This level suits organizations handling sensitive user data, such as payments, financial information, customer accounts or regulated transactions, across several domains.

EV confirms that your organization is legally registered, operational, and authorized to request the certificate, alongside control of every domain on the order. It also includes a verification call to your main listed business number, confirming that the request and the person making it are genuine.

Issuance timeframe
- Domain control verification: same day
- Business and authority verification: 1 to 5 business days
- Issuance follows once all checks are complete

Frequently asked questions

A Multi-domain SSL certificate, also called a SAN or UCC certificate, secures several separate domain names on one certificate. It suits businesses running multiple websites, brands or services that want one certificate to manage instead of one per domain.

A Multi-domain SSL secures separate domain names, such as example.com, example.net and brand.org. A Wildcard SSL secures one domain and its first-level subdomains, such as blog.example.com and shop.example.com.

Choose Multi-domain if you run several separate domains. Choose Wildcard if you run many subdomains under one domain.

Every certificate covers three domains as standard, and you can add more as SAN entries up to 210 in total.

Yes. You add or replace domains at any time by reissuing the certificate, and the reissue is free. Your expiry date stays where it was. This is what makes a Multi-domain SSL a good fit for growing businesses, migrations and changing infrastructure.

Yes. Each domain you list covers both its www and non-www version, set up for you when the certificate is issued.

Yes. Multi-domain SSL certificates are widely used to secure Microsoft Exchange, Office communications, mail servers and collaboration tools, where several hostnames need protecting under one certificate.

Multi-domain SSL is available at two validation levels. Domain Validation (DV) issues fast on a domain control check. Extended Validation (EV) verifies your registered company and shows its name in the certificate. Both use the same strong encryption and differ only in the depth of identity verification.

A DV Multi-domain SSL is typically issued within minutes of the domain check passing. An EV Multi-domain SSL usually issues within 1 to 5 business days, once business verification is complete. We guide you through each step to keep the order moving.

A longer term lowers the price per year and means fewer renewals to handle. Certificates are still reissued each year under industry rules, but you settle the term upfront and take the renewal admin off your plate for the length of the plan.

Yes. Multi-domain SSL certificates use up to TLS 256-bit encryption, the same as single-domain and wildcard certificates, so they are suitable for logins, transactions, customer data, APIs and sensitive communications across several domains.

You add a small record to each domain's DNS, or reply to an approved authorization email. For DNS, Sectigo gives you either a CNAME record pointing to a validation target, or a TXT record at _pki-validation.your-domain.com holding a unique value that stays valid for 30 days. Once the record is detected, control is confirmed automatically. Email validation is also supported, but only to a role address on your domain: admin@, administrator@, webmaster@, hostmaster@ or postmaster@. WHOIS email addresses are no longer accepted.

Three things keep an EV order moving. Your registered legal name, exactly as it appears on the public business register, since the certificate is issued under that name. A physical business address where you operate, not a PO box, virtual office, mail forwarding service or registered agent address. And a main business phone number that is publicly listed and answerable, since the verification call goes there. Sole traders and partnerships are verified against the principal individual, so the legal name is the owner's full name. A certificate cannot be issued under a trade name or DBA alone.

If any part of validation cannot be confirmed at first, we contact you with clear resolution options, so you are never left guessing about where the order stands.

Every domain on one renewal date

One certificate lists every domain you run, on a single renewal date. Installation is included when your sites are hosted with us.
