Website Security Checker
Check HTTPS, security headers, mixed content and warning signs in the address itself, such as hidden logins and look-alike domains.
About the Website Security Checker
Review visible technical security signals on a public page, including HTTPS, selected response headers, mixed-content references and a few warning signs in the address. It is a first-pass check for a website owner, not a malware scan or a verdict on trustworthiness.
How it works and an example to tryShow less
How to use the result
The checker reads the public response and awards a technical score for an HTTPS address, selected security headers and the absence of obvious HTTP references inside an HTTPS page. It also flags credentials embedded in a URL and possible internationalised look-alike domains. It does not query external reputation lists or examine a site's software for vulnerabilities.
Example to try
Run the check on your homepage and inspect which security headers are reported missing. Add or adjust a header in staging, then retest. Do not conclude that a site is safe solely because it has HTTPS or a high score here.
Questions
Who uses it, and when
Small-business site owners without a security team, editors checking a site before linking to it, and developers wanting a quick list of missing security headers.
Mistakes worth avoiding
- Assuming HTTPS alone makes a site safe.
- Ignoring mixed content that loads images or scripts over plain HTTP.
- Treating a good score as proof the site's software is patched.
