How Can You Tell If Your Site’s Security Certificate Is Valid?

A valid security certificate is the foundation of a trusted and successful website. It’s a critical signal to both visitors and search engines that your site is secure and authentic. Without one, you risk prominent browser warnings that drive away potential customers, damage your brand’s reputation and negatively impact your SEO rankings.

Simply put, keeping your security certificate current is essential for maintaining a professional and reliable online presence. At NUVEW Web Solutions, we specialize in managing these crucial technical details, ensuring your website operates flawlessly and securely at all times. We empower businesses like yours to focus on growth, confident that their digital foundation is solid.

There are several ways to verify the validity of your website’s security certificate, such as by:

• Using your browser’s padlock icon to check certificate status
• Identifying key details of the certificate issuer
• Monitoring your certificate’s expiration date to prevent lapses
• Recognizing common HTTPS errors that indicate a problem

How Do You Use the Browser Padlock to Check Your Certificate?

The fastest way to verify your security certificate is to look at your browser’s address bar. A valid certificate will display a padlock icon next to your URL, and the address will begin with https:// rather than http://.

To view your full certificate details in Chrome:

• Click the padlock icon in the address bar
• Select “Connection is secure”
• Click “Certificate is valid” to open the Certificate Viewer

Firefox and Edge follow a similar process. Simply click the padlock icon and navigate to the certificate information. If no padlock appears or you see a warning symbol, your certificate may be invalid or improperly installed.

What Certificate Issuer Details Should You Look For?

Once you have opened the certificate viewer, review the issuer information carefully. A valid TLS certificate should be issued by a trusted Certificate Authority (CA), a recognized third-party organization responsible for verifying your site’s identity.

Key details to confirm include:

• The certificate is issued by a reputable CA
• The domain name on the certificate matches your website’s URL
• The certificate has not been revoked

If the issuer is unknown or the domain name does not match, browsers will flag your site as potentially unsafe. This can drive visitors away and erode the credibility you have worked hard to build.

How Do You Monitor Your Certificate’s Expiration Date?

All TLS certificates have a limited lifespan. Currently, certificates cannot exceed 398 days: roughly 13 months. Once a certificate expires, browsers immediately mark your site as insecure.

To avoid this, check the “Validity Period” section within your certificate viewer. It will show both the issue date and the expiration date. Best practice is to begin the renewal process well before that expiration date arrives. Setting up calendar reminders or using automated monitoring tools can help ensure you never let a certificate lapse.

What HTTPS Errors Should You Watch For?

Certain error messages are clear signals that your certificate needs attention. Common ones include:

• Your connection is not private: The certificate is expired, invalid or untrusted
• NET::ERR_CERT_DATE_INVALID: The certificate’s date is out of range
• SSL_ERROR_BAD_CERT_DOMAIN: The certificate does not match the domain
• Certificate Not Trusted: The issuing authority is not recognized by the browser

Each of these errors can cause visitors to leave your site immediately. Addressing them promptly with the help of a web developer protects both your users and your online reputation.
