Have you ever heard of a san certificate? By the way how many certificates that you know? Which ones can still meet your demands at lower budget? There are so many certificates right?
Many businesses end up having multiple domains, subdomains or applications that require SSL protection as websites become more complex. With the complexity of websites, businesses often have multiple domains, subdomains or applications that require SSL protection. It can be a cumbersome process to buy and renew certificates one by one, particularly for IT teams with limited resources. This is where a SAN certificate (Subject Alternative Name certificate) comes in handy. A SAN certificate can be used to protect more than one domain name, which cuts down on the cost and complexity of managing certificates. Knowing the difference between SAN certificates and regular single domain certificates, as well as knowing when they are most appropriate can help businesses to make their entire SSL strategy much simpler.
What is special about SAN certificates?
A SAN certificate contains several domain names in a single certificate file, as opposed to a regular SSL certificate that only secures one domain. This allows you to get one certificate for your primary domain as well as several other unrelated domains, all of which are validated and encrypted by a single issuance. SAN certificates are flexible, unlike wildcard or standard certificates, because they can be used to add several names.
Setting them on a single domain.
SAN certificates are typically used by businesses with multiple branded sites, regional domains or microsites to manage multiple certificates instead of dozens. A single SAN certificate bundles all the above into one easy-to-manage package, which saves time for both IT and security staff.
Assisting with multiple Domain Structures
The certificates are also useful when a company wants to register a domain that isn’t a subdomain of another domain, which is not possible with wildcard certificates because they are only valid for subdomains of a single base domain. This flexibility makes SAN certificates an ideal option for organizations that have acquired brands or domain names that are not related, but under the same security umbrella.
The efficiency of cost and renewal.
A SAN certificate will have a single certificate renewal date and a single cost model, instead of having to pay for and renew multiple certificates at different times. This helps to minimize the chance of a certificate expiring on one domain when managing multiple domains, which is a typical and expensive certificate management error.
When You May Not Need One
A wildcard certificate might be a better and less expensive solution than a SAN if a business has just one domain and a limited number of subdomains. SAN certificates are particularly useful for multiple different domain names, rather than just subdomains, to be covered by a single certificate.
Conclusion
For enterprises with several domains that are not structured in a similar way, SAN certificates provide a convenient way to manage security policies in one place, instead of managing them on each domain. They offer lower administration costs, ease renewal, and offer coverage options that are not available with other certificate types. If an organization has multiple domain names, it’s a good idea to consider if a SAN certificate is appropriate for their infrastructure.
