Most Certificate Authorities allow the businesses to include a seal on their website, stating that the site is protected adequately by a Multi-Domain Wildcard SSL Certificate. These site seals are static or dynamic, allowing the businesses to insert it anywhere on their website. The site seal assures visitors that the communication with the website is secure and free from unauthorized access by others.

Benefits of the SAN Wildcard SSL Certificate

Better management

The Multi-Domain Wildcard SSL Certificate allows you to manage the certificate better as it will enable the webmaster to have a single relationship with the selected CA. There is no need to set up multiple alerts for upcoming renewals with multiple vendors. Moreover, they need to get involved in post-sales support with only one CA.

Saves cost

A Multi-Domain Wildcard SSL Certificate also helps to cut down on the cost of procuring multiple SSL certificates for each of the domains and underlying sub-domains that the business must secure. The webmaster can secure multiple such domains and sub-domains altogether and entrust with a single CA. It saves the effort to research about multiple certificates and procure multiple such certificates.

Time of issuance

The time of issuance of the certificate depends on the type of certificate that is requested. They can usually be issued within a few minutes. However, if you choose an organization validation certificate, it can take you up to three days. The business also needs to submit various legal documentation in their support.

Multiple browser compatibility

The selected SSL certificate needs to be compatible with the browser that the visitor is using. Else there could be an error. You may rest assured as most CAs offer a Multi-Domain Wildcard SSL Certificate that is compatible with multiple browsers.

Warranty level

Most CAs also provide a pre-defined amount as the warranty if the CA by mistake issues wrong certificates. This is another proof of the robust security standards deployed by the CAs. The warranty amount is different across several CAs. You need to do some research to find out the warranty amount for the CAs.

Points to note before choosing one

non-www domains

Few CAs may not automatically secure the non-www domain names. Do check this before procuring.

Common Name Domain

Always ensure that the Certificate Signing Request has a non-wildcard name as the common name. The wildcard name must be included as a SAN.

Conclusion

As the risk of data breaches continues to increase, webmasters must start processes to keep the websites free from cyber attacks. It is ideal to procure a Multi-Domain SAN SSL to secure all domains and underlying sub-domains. It will help you breathe easily and help streamline your security processes and be within your budget.
