How to Check if Your Website’s SSL Certificate Is Still Secure

An SSL certificate encrypts communication between your website and its visitors, protecting sensitive data like login details and payments. When it expires or becomes invalid, browsers stop recognising the site as secure and display warnings that can drive customers away.

For African businesses, maintaining a valid SSL certificate is essential for trust and compliance. An expired or misconfigured certificate damages credibility, interrupts sales, and can block visitors from accessing your site.

This guide shows how to verify your SSL certificate’s status, the tools to test it, and how SSL Africa’s support team can help you fix issues before they affect customers.

Quick Ways to Test SSL Validity Using Free Tools

You do not need technical training to confirm if your SSL certificate is active and configured correctly. Several free tools can run instant checks and display the results in seconds.

1. SSL Africa’s Support Team

If your certificate was purchased through SSL Africa, you can contact support for a quick validation check. The team can confirm whether your SSL is active, identify renewal dates, and guide you through reinstallation if needed. This is the fastest option if you are unsure which Certificate Authority issued your certificate.

2. Online SSL Checkers

Free tools such as SSL Labs’ SSL Server Test and DigiCert SSL Checker show detailed information about your certificate, including expiry date, encryption strength, and installation chain. Simply enter your website URL to see a full report.

Check that:

  • The certificate is valid and not expired.
  • The domain name matches your site.
  • No weak ciphers or mixed-content warnings appear.

3. Browser Security Indicators

You can also inspect SSL status directly in your browser. Click the padlock beside your site address and view certificate details. Look for:

  • A valid issuer such as Sectigo, Thawte, or PositiveSSL.
  • An expiration date that is still in the future.
  • Your organisation name if you use an OV or EV certificate.

4. Command Line Checks (for advanced users)

Developers can run terminal commands such as openssl s_client -connect yourdomain.com:443 to view the certificate chain and expiry date. This method is efficient for diagnosing issues on multiple servers.

Regular checks prevent sudden expiry or browser errors that can interrupt business operations.

Common SSL Issues and How to Resolve Them

Even a valid SSL certificate can cause browser warnings if it expires, is installed incorrectly, or does not match your domain. Recognising these issues early helps maintain customer trust and prevent downtime.

1. Expired Certificates

SSL certificates expire after a set period, usually one year. When this happens, browsers warn visitors that the connection is not private. Renewing the certificate immediately restores secure access.

2. Incorrect Installation

If the SSL chain is incomplete or installed on the wrong server, browsers may reject it. Double-check your installation settings and confirm that all intermediate certificates are included.

3. Domain Mismatch

A certificate must match the exact domain it protects. Errors occur when a subdomain or alternate version of the URL is not covered by the certificate. Reissuing or updating the certificate with the correct domain resolves this.

4. Mixed Content

When a page loads elements such as images or scripts over HTTP instead of HTTPS, browsers mark it as only partially secure. Updating all resource links to HTTPS removes the warning.

5. Outdated Security Protocols

Older servers using deprecated SSL or TLS versions can fail modern browser checks. Updating your server configuration to current TLS standards keeps encryption strong.

If you discover any of these issues, your Certificate Authority or SSL provider can help verify configuration details or guide you through renewal. Businesses using SSL Africa certificates can reach out to our support team for quick verification or setup advice.

Why Expired Certificates Damage Customer Trust

An expired SSL certificate immediately affects how customers perceive your business. Modern browsers display a full-screen warning that says the connection is not private. Many users will close the page rather than risk entering their information.

Expired certificates also disrupt online payments, form submissions, and third-party integrations that depend on secure connections. For eCommerce stores, this can mean instant revenue loss. For professional or corporate sites, it can harm credibility and search visibility.

Search engines treat secure connections as a ranking factor. When your SSL lapses, search visibility can drop until the certificate is renewed and verified again.

Regularly checking your SSL status ensures that visitors see your website as safe, professional, and trustworthy. Keeping certificates active shows that your business takes data protection seriously and values customer security.

If your certificate is approaching expiry, you can renew early through your Certificate Authority or contact SSL Africa for a replacement from trusted providers such as Sectigo, Thawte, or PositiveSSL.
