An SSL (Secure Sockets Layer) certificate is the digital padlock that keeps your website safe. It encrypts the data passing between your web server and your visitors' browsers, ensuring that sensitive information like passwords, emails, and credit card numbers cannot be intercepted by hackers. Our SSL checker allows you to instantly verify that your certificate is installed correctly, trusted by major browsers, and fully up to date.
If your SSL certificate expires, or if it is issued by an untrusted authority, browsers like Google Chrome and Apple Safari will immediately block visitors from entering your site, displaying a massive red "Not Secure" warning. This instantly kills consumer trust and drives potential clients straight to your competitors. Running a routine SSL audit ensures your certificate chain is unbroken and your visitors feel safe.
Sometimes you can successfully install an SSL certificate, but your browser still won't show the green padlock. This is usually caused by "Mixed Content"—meaning parts of your website (like images or scripts) are still loading over an insecure HTTP connection. Our tool helps you verify your baseline encryption, giving you the foundation needed to hunt down site-level vulnerabilities and secure your online presence.
Don't get caught off guard by an expired certificate. Instantly verify the exact "Valid From" and "Valid To" dates of any domain's SSL deployment.
Check the Certificate Authority (CA) that issued the padlock. Verify whether it is a free Let's Encrypt certificate or a premium Extended Validation (EV) setup.
Your security queries are completely anonymous. We do not store your search history, meaning you can silently audit competitors or your own private servers.
