Let’s assume you own the domain domain-for-ssl.com and an online store available at shop.domain-for-ssl.com.
In this case, both addresses can be secured with a single SSL certificate — as long as it is a Wildcard certificate. In our offer, you can find such a solution, for example RapidSSL Wildcard, which is designed specifically to protect multiple subdomains under one main domain.
It is important to understand how this type of certificate works. A Wildcard SSL protects first-level subdomains, meaning those directly connected to the main domain. This means it will secure both:
- https://domain-for-ssl.com
- https://shop.domain-for-ssl.com
However, it will not cover more complex addresses such as:
- https://www.shop.domain-for-ssl.com
This is because this is already a second-level subdomain — in simple terms, a deeper level of subdomain structure (an address containing more than one dot before the main domain name).
In summary, a Wildcard SSL is a very convenient and cost-effective solution if you want to secure multiple first-level subdomains under a single domain without purchasing separate certificates.
