Benefits of Wildcard SSL Certificate

As we all know, corporations use Secure Sockets Layer (SSL) certificates for their domains in order to maintain data security and to restore consumer confidence in their products and services. SSL (Secure Sockets Layer) is a standard security technique that allows companies to establish an encrypted connection between a web server and a client.

As a result, attackers will be unable to intercept data flow (between a web server and a client) and use the information obtained. An SSL certificate is a must-have for every business that conducts e-commerce or collects sensitive information.

The advantages of having an SSL Certificate are innumerable; yet, if a new firm intends to have multiple subdomains under a single domain, this can be a difficult operation to accomplish. Wildcard SSL Certificates have proven to be quite beneficial for such websites, as they have reduced their time and expenses.

What is a Wildcard SSL Certificate?

An SSL certificate with a private key that can secure all connected (unlimited number of) first-level subdomains of the parent domain eliminates the need to purchase separate SSL certificates for each of them. Using this feature, you can select extra hostnames to be secured by a single certificate. These can include email addresses, IP addresses, URLs, DNS names, and so on. Briefly stated, a Wildcard SSL Certificate allows you to secure an unlimited number of sub-domains under a single domain name.

As an illustration:

A single wildcard certificate for the domain https://*.https.in will secure all of the subdomains on the https://*.https.in domain, including the following subdomains:

payment.https.in \scontact.https.in \slogin-secure.https.in \swww.https.in
Let’s take a look at the advantages of Wildcard SSL Certificates and why you should consider purchasing a wildcard SSL certificate.

SSL Administration Made Simple
Wildcard SSL Certificates not only save you money by allowing you to secure an unlimited number of sub-domains, but they also make things simpler to administer.

Furthermore, you will be required to repeat the practise at each renewal, which will consume a significant amount of your time and resources.

Certificates are issued in the shortest time possible.
Customers can obtain a Wildcard SSL certificate in as little as two days because the certificate does not require the same lengthy verification processes as an extended validation (EV) certificate. If the CA uses the domain verification method to validate the firm, the certificate will be issued in a matter of minutes.

The sole disadvantage of Wildcard Certificates is that, because they share a similar private key across all servers, if one server is compromised, it can make all other servers subject to the same attack. However, given the complexity of the encryption, this is extremely unlikely to occur in practise.

Finally, Wildcard SSL Certificates are the ideal option because they not only save money while protecting an unlimited number of sub-domains, but they also make things simpler to handle.
