Tips and Tricks for Implementing a Wildcard SSL Certificate

Best practices and mistakes to avoid to ensure maximum security

When it comes to implementing a Wildcard SSL Certificate, there are certain best practices that you should follow to ensure maximum security and avoid common mistakes. So whether you’re a website owner looking to improve your site’s security or a web developer looking to learn more about SSL Certificates, keep reading to learn everything you need to know.

SSL Certificates Protect Sensitive Information

Before we dive into the specifics of Wildcard SSL Certificates, let’s first recap the importance of SSL Certificates in general. SSL Certificates are a crucial component of website security, as they encrypt data that is transmitted between a user’s web browser and a website’s server. This helps to protect sensitive information such as login credentials, credit card numbers, and other personal data from being intercepted by hackers.

Without the protection of SSL Certificates, websites are vulnerable to various types of cyber attacks, including man-in-the-middle attacks, phishing scams, and data breaches. Website owners need to ensure that their sites are secured with SSL Certificates.

Secure Multiple Subdomains with Wildcard SSL Certificates

Now, let’s talk about Wildcard SSL Certificates specifically. A Wildcard SSL Certificate allows you to secure multiple subdomains with a single certificate, making it a cost-effective and efficient option for websites with a large number of subdomains – for example, e-commerce websites, SaaS providers, or content management systems (CMS).

In addition to multi-subdomain protection specific to Wildcard SSL Certificates, all SSL Certificates, including Wildcard SSL Certificates, also have the additional benefit of increasing the site’s search engine optimization (SEO) and establishing legitimacy and trust to your site’s visitors.

Checklist for Implementing a Wildcard SSL Certificate

Choose a reputable SSL provider

It is important to choose a trusted SSL provider that offers a reliable Wildcard SSL Certificate. Some Wildcard SSL Certificates can also have compatibility issues with certain devices or browsers, which could result in SSL errors. To avoid this, check your chosen Wildcard SSL Certificate’s browser compatibility before purchasing.

Plan your Wildcard SSL deployment

Before you begin implementing your Wildcard SSL Certificate, it is important to plan out your SSL deployment. This includes identifying all the subdomains that will be secured by the certificate and creating a detailed deployment plan.

 Generate a strong private key – and keep it safe!

A strong SSL private key is a critical component in ensuring secure communication between a server and client. It is something that we’d absolutely recommend be kept secret and secure to prevent unauthorized access to sensitive data.

When generating your private key, make sure to use a strong algorithm (such as RSA) and a key length of at least 2048 bits.

Install and test the certificate correctly

Whichever provider you choose, it is important to follow the installation instructions provided carefully to ensure that the certificate is installed correctly on all subdomains. Once your certificate is installed, test your SSL configuration thoroughly to ensure that it is working correctly and all subdomains are secured.

Bonus Tip – make sure to look into available troubleshooting and support resources available from a prospective provider before making a final decision. Being able to get in touch with someone if you need extra assistance is going to make all the difference when it comes to installation and if you run into any issues when testing.

3 Common Mistakes to Avoid When Implementing a Wildcard SSL Certificate

When it comes to implementing a Wildcard SSL Certificate, there are several common mistakes that website owners and developers should avoid. These mistakes can compromise the security of the certificate and leave websites vulnerable to cyber attacks. Here are three of the most common mistakes to avoid and how to ensure maximum security for your website.

1. Not securing all subdomains

One of the most common mistakes when implementing a Wildcard SSL Certificate is failing to secure all subdomains. Make sure to identify and secure all subdomains that need to be protected by the certificate. It might feel like an obvious one, but we’d recommend triple checking this one!

2. Using weak encryption

Using weak encryption algorithms or a short key length can compromise the security of your Wildcard SSL Certificate. Make sure to use strong encryption algorithms and a key length of at least 2048 bits to ensure maximum security.

3. Failing to keep your Wildcard SSL Certificate up to date

All SSL Certificates, even Wildcard SSL Certificates, are only valid for up to a year and will expire unless renewed. Failing to renew your certificate on time can result in your website being flagged as unsecured, which can impact user trust and website traffic. Adding a recurring reminder to your calendar can remind you to renew the certificate before it expires, keeping your certificate up to date. However, a good SSL provider will make sure to remind you of upcoming expirations.
