Description

HeaderGenie Security Headers sends HTTP security headers from PHP, so they work on Apache, Nginx, and hosts that ignore .htaccess.

You can:

Scan the public site and see which security headers are present, weak, or missing
Enable safe defaults such as X-Content-Type-Options, X-Frame-Options, Referrer-Policy, DNS prefetch control, and HSTS on HTTPS
Manage those headers from HeaderGenie in wp-admin

The scanner and headers work with no account and do not contact HeaderGenie servers.

A separate HeaderGenie Pro plugin, sold at headergenie.com, adds Content-Security-Policy, extra headers, and cloud monitoring. That plugin is not included here and is not required.

This plugin does not guarantee legal or compliance outcomes. It helps you set and review security headers.

Privacy

This plugin does not contact HeaderGenie servers and does not require an account. A scan requests your own public site URL from the WordPress server so it can read response headers. No analytics, license checks, or third-party tracking run in this plugin.

Installation

Upload the headergenie-security-headers folder to /wp-content/plugins/ or install from Plugins Add Plugin.
Activate HeaderGenie Security Headers.
Open HeaderGenie in the admin menu.
Run a scan, then enable the headers you want.

FAQ

Does this plugin need an account?: No. Scanning and the included security headers work locally.
Does the plugin change .htaccess?: No. Headers are sent from PHP on front-end and login responses.
Will this break my site?: The included headers are conservative. They are not applied to wp-admin, AJAX, REST, or XML-RPC.
Does this plugin phone home?: No. It only requests your own public site URL when you run a scan. Local development can set HEADER_GENIE_SCAN_URL in wp-config.php if the public URL is not reachable from PHP. It does not contact HeaderGenie servers.
What is HeaderGenie Pro?: A separate plugin from headergenie.com. It is optional and is not part of this download.
