If companies require multiple web addresses, two types of certificates frequently are mentioned: SAN certificates and wildcard certificates. Both provide coverage beyond a single domain, but they are quite different in their approach and are appropriate to different situations. Mixing the two up can cause businesses to buy the right solution for the wrong price, or they might end up not having coverage for domains that do not align with the certificate’s structure. The fundamental difference between SAN ssl and wildcard certificates can guide businesses to select the right certificate for their domain structure and growth plans.
- Each certificate type covers specific types of work
A wildcard certificate protects the main domain name and all first-level subdomains of that domain, like blog.example.com or shop.example.com. A SAN certificate, however, can be used to obtain several completely different domain names, like example.com and anotherbrand.com.
- Ideal Use Cases
Wildcard certificates are ideal for companies that are adding more subdomains to an existing domain for various purposes, such as blogs or portals. For organisations with multiple different brands, acquired companies or regional domains with different root domain structures, SAN certificates are suitable.
- Flexibility in Domain Structure.
Unlike wildcard certificates, SAN certificates are more flexible, as they can include unrelated domains in the same certificate. However, wildcard certificates automatically cover all subdomains without the need to add each new subdomain as would be necessary with SAN certificates for each domain name.
- The differences between the management and renewal.
Businesses that often add new subdomains will find that wildcard certificates make it easy to manage. Unlike other certificates, SAN certificates need to be added to the certificate when it is issued or renewed, and will not be automatically added to the certificate.
- Cost Considerations
The price of both types of certificate may differ depending on the provider, but the SAN certificate may increase in price depending on the number of domains it covers, while the wildcard certificate may be priced at a flat-rate regardless of the number of subdomains that are added to the primary domain.
- Compliance with relevant international standards.
Businesses need to take into account their online presence growth when deciding which certificate to go for, SAN or Wildcard. Wildcard certificates offer seamless scalability if future expansion is primarily going to be through new subdomains under a single main domain. But if the organization plans to add new domains to its website with different root names, a SAN certificate will be more flexible as it will enable them to manage several domains with a single certificate.
8.The security and administrative efficiency of the system.
While both SAN and Wildcard certificates offer the same amount of SSL/TLS encryption, they are different in the way they ease certificate administration. A Wildcard certificate can save a lot of administration time because it automatically enrolls eligible subdomains, whereas a SAN certificate can save certificates for organizations with multiple different domain names. Selecting the right certificate can decrease management complexity, decrease operational costs and enhance overall security administration.
Conclusion
The decision of SAN vs. wildcard certificates depends on your domain structure and future growth plans. Organizations that are expanding a single domain with multiple subdomains will probably prefer wildcard certificates, whereas those with multiple different domain names will enjoy the flexibility offered by SAN certificates. It’s important to plan your domain requirements in the present and the future to ensure you get the right certificate for your business.
