Basics

What is a Wildcard SSL certificate?

A Wildcard SSL certificate secures all first-level subdomains of a domain with one certificate. The certificate is issued in the form *.example.com, so subdomains such as www, mail, panel, api and shop all use the same certificate.

When you create a new subdomain, you do not need to buy another certificate or reissue the existing one. Wildcard is offered with domain validation (DV) and organization validation (OV); EV certificates are not available as Wildcard.

  • Coverage*.example.com — unlimited first-level subdomains
  • Not coveredSecond-level subdomains (a.b.example.com) and other domains
  • Validation typesDV and OV (no EV)
  • Validation methodEmail or DNS record
Pricing

Wildcard SSL certificate prices

DATASSL offers 18 Wildcard SSL products; annual prices start at $40.00. Below are the best-priced DV and OV Wildcard options of each brand (per year, excl. VAT).

Setup

How to get and install a Wildcard SSL certificate

A Wildcard certificate is ordered like a regular SSL certificate; the difference is that the CSR is generated with the asterisk domain and validation is carried out on the main domain.

1

Generate the CSR with *.example.com

When generating the CSR, enter *.example.com in the common name (CN) field. Your private key stays on your server.

2

Validate the domain

Wildcard certificates are validated by email approval or DNS record; the file upload method cannot be used.

3

Organization validation for OV

For OV Wildcard, the certificate authority also verifies your organization using official records; this step usually takes 1–3 business days.

4

Install on your servers

You install the same certificate and private key on the servers that host your subdomains.

Copying the same private key to multiple servers means that if one server is compromised, all subdomains are affected. Consider securing critical systems with a separate certificate.

Use cases

Who should use Wildcard SSL?

Sites with many subdomains

You manage subdomains such as www, mail, panel and api with one certificate.

SaaS and customer subdomains

In applications that give each customer an address like customer.example.com, new addresses are covered automatically.

Hosting providers and agencies

On infrastructure where new subdomains are created frequently, it removes the burden of buying and renewing certificates one by one.

Test and staging environments

Environments such as test, staging and dev are all encrypted with the same certificate.

FAQ

Frequently asked questions about Wildcard SSL

How much does a Wildcard SSL certificate cost?

At DATASSL, Wildcard SSL certificates start at $40.00 per year (excl. VAT). The lowest-priced DV Wildcard product is Certum Commercial Wildcard SSL ($40.00). OV Wildcard options start at $90.00.

How many subdomains does a Wildcard SSL certificate cover?

There is no limit on the number of first-level subdomains: a *.example.com certificate covers addresses such as www.example.com, mail.example.com and api.example.com.

Does Wildcard SSL also cover the main domain (example.com)?

With most products, example.com is added to the certificate together with *.example.com. Coverage can vary from product to product, so check the details on the product page.

Does Wildcard SSL cover second-level subdomains?

No. A *.example.com certificate does not cover second-level addresses such as a.b.example.com. That requires a separate Wildcard certificate for *.b.example.com or a multi-domain certificate.

How is a Wildcard SSL certificate validated?

The domain is validated through an approval link sent to an administrative email address or through a record added to DNS. Under CA/Browser Forum rules, the file upload (HTTP) method cannot be used for Wildcard certificates.

Is there an OV Wildcard SSL certificate?

Yes. With an OV Wildcard certificate, your organization is validated as well as the subdomains, and the organization name appears in the certificate. The lowest-priced option is Certum Trusted Wildcard SSL at $90.00 per year (excl. VAT).

Is there an EV Wildcard SSL certificate?

No. CA/Browser Forum rules do not allow Wildcard in EV certificates. To secure multiple addresses with EV, a multi-domain (SAN) EV certificate is used.

Can a Wildcard SSL certificate be installed on multiple servers?

Yes, the same certificate can be installed on the different servers that host your subdomains. Server license terms can vary from product to product, so check the product page.
