About the Security Headers Generator

The Security Headers Generator generates a complete set of security headers for Apache, Nginx or PHP, with each one explained. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.

What people use it for

  • Hardening a site on shared hosting.
  • Passing a security scan.
  • Understanding what each header actually protects against.
Enable HSTS with a short max-age first. Once a browser has seen a long-lived HSTS header it will refuse plain HTTP for that domain for the full duration, and there is no way to undo it from the server side if your certificate breaks.
