Wildcard SSL Certificate – Best Choice for Subdomain Security

There has been a manifold increase in the number of internet users. This has made many businesses go the online route to reach out to more of their audience. Gradually, the website has become the best source of leads for most companies. As more users go online to search for solutions, hackers are also increasingly targeting websites to get hold of critical customer data. The number of cyber-attacks has increased.

Businesses must thwart these attacks and must deploy adequate steps to prevent them. The threat to data security is equal for the industry behemoths as well as small companies. Studies show that data breaches had exposed around 36 billion records in the first half of 2020. It is recommended that businesses with multiple digital assets choose the right kind of SSL certificate to secure them. In this article, we will learn more about them and how they can help companies to thwart a cyberattack.

What is a Wildcard SSL?

The Wildcard SSL is a digital certificate that allows businesses to secure a primary domain and unlimited first-level sub-domains. For example, if your website has several sub-domains, it would not be easy to manage several different SSL certificates. It is where the Wildcard SSL certificate is helpful. You can remove the hassles of having to secure the sub-domains with separate certificates. 

Several businesses utilize the sub-domains for various other functions. Some of them can be client-facing too. The Wildcard SSL certificate helps to secure all these sub-domains together in one place. The certificate has a wildcard character in the field to include the domain name. It helps the certificate to secure several first-level sub-domains under the chosen primary domain.

The certificate uses the Public Key Infrastructure (PKI), and all the first-level sub-domains are protected. When using the Wildcard, in the field for the domain, you must use an asterisk (*) to show where the sub-domain would be. 

For example, the certificate that has been issued for *.website.com will also support blog.website.com, news.website.com, careers.website.com, mail.website.com, account.website.com, etc.

Once the certificate is installed, the communication taking place between the visitor’s browser and the webserver will be encrypted. They are available only in Domain Validation and Organisation Validation levels only.  You can install a cheap Wildcard SSL from CheapSSLShop to ensure the security of all the first-level sub-domains.

The server would have a private key that can unlock the message. The second-level sub-domains cannot be covered within the same certificate. You must have another Wildcard SSL certificate for the second-level sub-domains or buy a multi-domain wildcard SSL cert. The private key is shared across all the sub-domains. 

Benefits of having a Wildcard SSL

Ensures user trust

Like all other SSL certificates, the Wildcard SSL certificates also ensure that users can safely visit any website where it has been installed. The user can see the padlock on the address bar too. Browsers like Google mark insecure websites as “Not Secure.” If you install the certificate, these warnings are removed too. Some Certificate Authorities (CAs) also provide a Trust Seal that can be placed at prominent areas on the website. E-commerce websites can place it at the checkout page to improve customer trust.

Domain Validation (DV) and Organisation Validation (OV). The certificates do not take much time to be issued. The DV certificates can be issued within a few minutes. However, the OV certificates take more time and may take even three days to be issued. 

Supports several sub-domains

These certificates can secure several sub-domains, thereby allowing you to collate your data security resources in one place. It removes the hassles of having to manage multiple service providers at the same time. It is ideal for larger companies with several digital assets. It also helps e-commerce companies that have several subdomains to be secured.
