The company has multiple domain names, does each domain install an SSL certificate?
Having multiple domain names can mean increased management complexity and maintenance costs. If your company has many domain names, it is not necessary to install SSL certificates for each of them. Instead of purchasing SSL certificates for each domain name, consider purchasing a multi-domain SSL certificate or a wildcard SSL certificate.
How Do I Decide to Choose a Multi-Domain SSL Certificate or a Wildcard SSL Certificate?
1.Coverage:
A multi-domain SSL certificate can protect multiple different domain names, including primary and subdomains. This means that you can use a single SSL certificate to protect your multiple domain names, without having to purchase separate certificates for each one. This type of certificate is typically suitable for businesses that have multiple domain names but need to manage them centrally.
If you have a large number of domain names and need to cover a large number of subdomains, wildcard certificates are more advantageous. A wildcard SSL certificate protects a primary domain name and all subdomains at its next level. If you have a lot of sibling subdomains, a wildcard certificate may be a more economical option because it allows all subdomains to be secured under one certificate without having to purchase separate certificates for each subdomain.
2.Budget:
Multi-domain SSL certificates are usually more expensive than wildcard SSL certificates because multi-domain certificates protect more domain names. So, if you're on a budget but have a large number of domain names that need to be protected, a wildcard certificate may be a more economical option.
3.Future Management and Deployment:
If you plan to add more subdomains or unique domains in the future, you may want to consider choosing a multi-domain SSL certificate so that you can easily add new domains to the certificate in the future.
It is important to note that:
When purchasing an SSL certificate, make sure to purchase it from a trusted certificate authority (CA) to ensure the validity and security of the certificate.
Consider future expansions and changes to your domain name, and choose a certificate type that has the flexibility to adapt to your needs.
Evaluate your budget and long-term costs to choose the certificate that best fits your financial situation.
To sum up, if your company has multiple domain names, you can consider purchasing a multi-domain SSL certificate or a wildcard SSL certificate instead of purchasing an SSL certificate separately for each domain name. The decision between a multi-domain SSL certificate and a wildcard SSL certificate should be based on your specific needs, budget, and domain name structure. Make sure you choose a certificate that meets your current needs and considers future scalability and flexibility.
