We recommend PositiveSSL Wildcard Certificate

You probably know that each SSL certificate is issued to a fully qualified domain name. This usual method becomes tedious when you need to secure a number of subdomains on the same domain name.

Wildcard SSL certificates are a convenient and cost-effective option that allows you to secure a main domain (also known as a Fully Qualified Domain Name or FQDN) and an unlimited number of sub-domains. So say your website is cleverly named, www.mywebsite.com.

A wildcard certificate would allow you to protect that domain, plus all accompanying sub-domains. For example, mail.mywebsite.com, ftp.mywebsite.com and login.mywebsite.com by simply using *.mywebsite.com in your CSR This easily makes wildcard certificates one of the best values available if you’re looking to secure multiple sub-domains without having to purchase an individual certificate for each one. Some people buy wildcard SSLs even if they only have one domain to secure at the moment, because you never know what the future holds. It is a marginal cost to future-proof your website, not to mention, it also simplifies the management of your SSL certificates.

With PositiveSSL Wildcard, you can easily secure an unlimited number of subdomains of the same domain. This certificate can be issued in 15 minutes or less.

* SSL certificates must be installed on your web server. Therefore, an end-to-end SSL installation support should be performed by your hosting provider. Please contact their support for assistance with CSR generation and SSL installation.

** Selected orders can be flagged for an additional “Brand Validation” procedure by Certificate Authority. This is a necessary security measure. If the order is flagged for “Brand Validation”, SSL issuance can be delayed for a time period deemed necessary by the Certificate Authority.

*** To make the certificate issuance process faster, you need to ensure that you have correct contact information on WHOIS for your domain. You also need to have a dedicated IP address (can be ordered at your web host), and a CSR generated on your web server for your domain name.
