Wildcard SSL Certificates: A Double-Edged Sword

Updated: Jun 29

In today's world, securing online data has become an utmost priority. SSL certificates are one of the most popular and effective ways to protect data transmission over the internet. An SSL certificate allows websites to secure the connection between the web server and the user's browser by encrypting the data transmitted between them.

However, using wildcard SSL certificates externally beyond the firewall can create a vulnerability for all public hosts. A wildcard SSL certificate is an SSL certificate that secures an unlimited number of subdomains under a single domain name. This means that if a hacker gains access to the wildcard SSL certificate, they can easily compromise the security of all the subdomains and create a potential threat to the entire organization.

Therefore, it is essential to use wildcard SSL certificates judiciously and not externally beyond the firewall. Companies should use separate SSL certificates for their internal and external subdomains to mitigate the risks associated with a wildcard SSL certificate.

On the other hand, Let's Encrypt offers a free SSL certificate solution for companies to secure their websites. Although not as secure as paid SSL certificates, it is still a viable option compared to no SSL. Google SEO also recognizes SSL certificates as a requirement for higher listings, and not having one can hurt website visibility.
