Wildcard Domain HTTPS Certificate VS Multi-domain HTTPS Certificate

Wildcard Domain SSL Certificate

A Wildcard Domain SSL Certificate, also known as a Wildcard SSL Certificate, can protect a domain and all its subdomains with a single certificate. This type of SSL certificate is widely used and suitable for corporate websites, e-commerce sites, blogs, etc., with many subdomains under the same domain. During the certificate validity period, you can add subdomain sites for free and unlimited times. In other words, the more subdomain sites you have, the higher the cost-effectiveness.

Multi-Domain SSL Certificate

The Multi-Domain SSL Certificate is the most flexible among all SSL certificates, as it can protect multiple independent domains simultaneously, including multiple main domains or multiple subdomains. If a company needs to protect multiple subdomains at the same time or different domains, using a Multi-Domain SSL Certificate can enhance website security and credibility. By default, the Multi-Domain SSL Certificate protects 3-5 domain records. If this is insufficient, additional protection can be purchased. Although the Wildcard Domain SSL Certificate allows free domain additions, the added domains must be subdomains of the same domain.

Conclusion

By comparing wildcard HTTPS certificate and multi-domain HTTPS certificate, we can see that each type of HTTPS certificate has its own advantages and disadvantages. When choosing the right certificate, it is necessary to consider the actual needs. If your website needs to protect multiple different domain names at the same time, or needs to manage multiple domain names in one certificate, then the multi-domain HTTPS certificate may be more suitable for you; if you only need to protect one domain and all its subdomains, then the wildcard HTTPS certificate may be more suitable for you.
