A Wildcard certificate, or subdomain SSL saves time and cost as there is no need to manage separate SSL certificates for each subdomain. With a single certificate, it secures the primary domain and its unlimited subdomains. For example, *.domain.com can secure subdomains like shop.domain.com and blog.domain.com.
With the main domain and all first-level subdomains covered under one installation, Wildcard SSLs are a cost-effective solution for businesses managing multiple subdomains and services. Buy Wildcard SSL certificates at SSL2BUY starting from $35.00/year, offering one of the most competitive Wildcard certificate prices available.

A Wildcard SSL certificate is a type of SSL/TLS certificate used to secure a domain along with its associated subdomains under a single configuration. It is commonly used in environments where multiple services or applications run on different subdomains of the same domain.
During an HTTPS request, the server presents its SSL/TLS certificate as part of the TLS handshake. The certificate contains a wildcard character (*) in the Common Name field, which allows it to match multiple first-level subdomains of the same domain during the validation process.
Because of this matching behavior, the same certificate can be used across different subdomains without issuing separate certificates. For example, connections to store.ssl2buy.com, secure.ssl2buy.com, and checkout.ssl2buy.com can all be secured and validated using a single Wildcard certificate.
Domain-validated wildcard SSLs require only domain ownership verification and are typically issued within minutes.
They are ideal for businesses and individuals who want basic SSL security for securing domains and subdomains with HTTPS, helping prevent “Not Secure” warnings.
OV Wildcards require domain and organization verification and are issued within 2 to 3 business days. The business identity is verified through official records before the certificate is issued.
Available in two types, single domain and multi-domain, it’s a recommended option for businesses that have websites with sub-domains or multiple websites or sub-domains and deal with sensitive user or organizational data.
Available in two validation levels, Domain Validation and Organization Validation, Multi-Domain Wildcard Certificates are a multipurpose SSL solution for multiple domains and sub-domains listed as SANs (Subject Alternative Names).
It’s a recommended SSL certificate for organizations managing multiple websites and subdomain structures within a single deployment.
A Wildcard SSL certificate appears similar to other SSL/TLS certificates in a web browser with a secure SSL connection and a padlock icon within the address bar & “HTTPS” at the start of the URL. However, the difference is seen within the certificate details, where an asterisk (*) is visible before the domain name. It indicates that it can secure sub-domains under the primary domain.
In most cases, the website visitor will not be able to see major differences unless they specifically check the installed SSL/TLS certificate details. To locate the Wildcard within the browser, follow the below steps:
If a website uses a Wildcard SSL certificate, the certificate details will display an asterisk (*) before the primary domain, such as *.ssl2buy.com.
Validation Timing: 10 Minutes
Domain Validation (DV) for Wildcard SSL is completed by verifying control over the domain. Firstly, CA (Certificate Authority) sends a verification request to the admin’s email address, which is available in the domain’s WHOIS record or via DNS record configuration. Once the CA confirms the domain ownership, the DV Wildcard SSL certificate is issued instantly.
Validation Timing: 1 to 3 Days
Organization validation requires businesses to submit their official documents to prove the legitimacy and operational existence to get an OV Wildcard SSL issued.
The Certificate Authority validates all the provided details against trusted third-party databases and may also get in touch with the company to get further details. The Wildcard SSL certificate is issued in the name of the organization once the verification process is completed.
A wildcard SSL certificate simplifies security by allowing a single certificate to protect a primary domain and all its subdomains, reducing cost and management effort.
