What Happens When Your SSL Certificate Expires? Risks & Solutions

In today’s digital landscape, an SSL certificate is essential for securing your website, protecting user data, and maintaining trust. However, many website owners often overlook their SSL certificate expiration date, which can lead to serious consequences.

When an SSL certificate expires, your website becomes vulnerable to cyber threats, security warnings appear for visitors, and your SEO rankings may drop. To prevent this, it’s crucial to monitor your SSL certificate and renew it on time.

In this blog, we’ll discuss what happens when an SSL certificate expires, the risks involved, and the best solutions to avoid expiration issues.

What Happens When an SSL Certificate Expires?

An SSL certificate (Secure Sockets Layer) ensures that data transmitted between a user’s browser and a website is encrypted and secure. When it expires:

  • The encryption protecting user data is no longer valid.

  • Browsers display security warning messages.

  • Search engines may penalize your site.

  • Visitors may lose trust and avoid your website.

Once expired, your SSL certificate cannot be extended—you must renew it or purchase a new one.

Risks of an Expired SSL Certificate

Allowing your SSL certificate to expire comes with severe risks that can affect your website’s security, reputation, and revenue.

1. Visitors See Security Warnings

When users visit a website with an expired SSL certificate, browsers like Google Chrome, Firefox, and Edge show security warnings:

“Your connection is not private.”

This warning discourages visitors from proceeding, which leads to a drop in traffic and damages your brand’s credibility.

2. Website Becomes Vulnerable to Cyber Attacks

Without a valid SSL certificate, your website’s encryption is disabled, making it easier for hackers to launch Man-in-the-Middle (MITM) attacks, steal sensitive data, and distribute malware.

3. Drop in SEO Rankings

Google prioritizes HTTPS-secured websites in search rankings. If your SSL certificate expires:

  • Your website may lose ranking positions.

  • Visitors may see "Not Secure" next to your website URL.

  • Search engines may reduce your visibility in search results.

4. Loss of Customer Trust & Revenue

For e-commerce websites, an expired SSL certificate is especially damaging. Customers will hesitate to enter credit card details or make purchases if they see security warnings. This can result in lost sales and revenue.

5. Website May Become Inaccessible

Some corporate firewalls and web browsers block access to sites with expired SSL certificates, leading to downtime and loss of potential customers.

How to Prevent SSL Certificate Expiry Issues?

To avoid the risks of an expired SSL certificate, follow these best practices:

Enable Automatic Renewal

Most SSL providers offer auto-renewal options. Enable this feature to ensure your SSL certificate renews before expiration.

Use SSL Monitoring Services

A 24/7 SSL monitoring tool like WebStatus247 can track your SSL certificate’s status and send alerts before it expires. This prevents unexpected downtime and security issues.

Set Up Expiry Alerts

If you don’t use an automated SSL monitoring service, set up manual alerts:

  • Use Google Calendar or reminder apps.

  • Register multiple email contacts with your SSL provider.

  • Schedule checks at least 30 days before expiration.

Purchase Multi-Year SSL Certificates

Some SSL providers offer multi-year SSL plans, allowing you to reduce the hassle of frequent renewals. This ensures long-term security.

Check Certificate Validity Period Regularly

Make it a habit to check your SSL certificate’s validity manually every few months. You can do this using online SSL checker tools or through your hosting provider’s dashboard.

Final Thoughts

An expired SSL certificate can cause security risks, SEO penalties, lost traffic, and revenue decline. To prevent this, enable auto-renewal, use SSL monitoring services, and set up alerts.
