An SSL Checker helps you verify whether your website's SSL certificate is correctly installed, trusted by web browsers, and configured according to modern security best practices.
Whether you're launching a new website, renewing an existing certificate, or simply performing routine maintenance, checking your SSL certificate regularly helps prevent browser warnings, security issues, and unnecessary downtime.
We're currently developing a free SSL Checker for Wikicert that will allow you to instantly verify your website's SSL configuration.
The tool will check:
Certificate validity
Certificate expiration date
Certificate issuer
Domain matching
Certificate chain
HTTPS configuration
Supported TLS versions
Overall SSL health
Our goal is to provide a simple, reliable tool that helps website owners identify SSL issues before they affect customers or search engine rankings.
Coming soon to Wikicert SSL Academy.
An SSL Checker is an online diagnostic tool that connects to your website and inspects the SSL/TLS certificate installed on your server.
Instead of simply checking whether HTTPS loads, an SSL checker examines several important aspects of your certificate and server configuration to ensure everything is working correctly.
A proper SSL check helps detect problems before visitors encounter browser warnings or connection errors.
Regular SSL checks help maintain a secure, trustworthy website.
Benefits include:
Prevent browser security warnings
Detect certificates nearing expiration
Confirm proper HTTPS configuration
Verify the complete certificate chain
Improve visitor confidence
Support search engine optimisation (SEO)
Reduce unexpected downtime
Even a valid SSL certificate can experience configuration issues after hosting migrations, server updates, or DNS changes.
Running an SSL check can quickly identify common issues such as:
Expired SSL certificates
Incorrect domain names
Missing intermediate certificates
Broken HTTPS redirects
Mixed content warnings
Weak TLS configurations
Invalid certificate chains
Improper server configuration
Finding these issues early helps prevent visitors from seeing security warnings in their browsers.
It's good practice to check your SSL certificate whenever significant changes are made to your website.
We recommend running an SSL check:
After installing a new SSL certificate
Before your certificate expires
After changing web hosts
Following DNS updates
After migrating your website
Following server maintenance
As part of your monthly website health checks
