PathFree tool
Check the HTTP security headers of a site
Enter a page address. The tool reads six security headers, including HSTS, CSP and X-Frame-Options, and gives a grade from A to F.
Frequently asked questions
How is the grade calculated?
The grade starts at 100. Each missing header removes points. HSTS and CSP weigh the most. A page served over http gets an F.
Does an A grade mean the site is secure?
No. Headers are only one layer of protection. The tool does not test the site’s code, its plugins or its passwords.
How do I add a missing header?
In the configuration of the server, the CDN or a security plugin of the CMS. Test the page after each change: a CSP that is too strict can block scripts.
