About TLS Security and Configuration Scanner

This tool scans the overall health and configuration of your TLS (HTTPS, simply put) in depth. With a simple scan, you immediately know whether there are any deep-seated issues within your TLS implementation, whether you’re open to some nasty vulnerabilities (like heartbleed, ROBOT), outdated encryption algorithms being used, and more.

Geekflare TLS scanner is powered by testssl.sh

Why you should care?

Just having a TLS system in place isn’t enough. If you want your site to be fully trusted by search engines and browsers, you need to make sure the foundations are also right. One such foundational setting is the certificate chain (not all Certificate Authorities are on the same level), which if not properly set up, will cause browsers to reject your website as insecure (Firefox & Chrome is especially strict).

Besides, having any other weak link in your TLS ecosystem instantly opens you up as a hacking targets (both automated and manual), the results of which can be catastrophic for your website.
