Security Hardener is inspired by the official WordPress hardening guide (Advanced Administration / Security / Hardening). It uses the platform’s standard functions and does not override core. Applies a prudent set of defenses:
- Security headers:
X-Frame-Options,X-Content-Type-Options,Referrer-Policy,Permissions-Policy,COOP/CORP. - HSTS (optional; HTTPS only).
- Basic nonce-based CSP (optional; requires testing).
- Disable XML-RPC and pingbacks (optional; enabled by default).
- Hide the WordPress version in the
<head>. - Block user enumeration via
/?author=by returning 404. - Generic login errors (prevents information leakage).
- IP-based login rate limiting with transients (configurable threshold and window).
- Restrict the REST API to authenticated users, with a minimal allowlist for oEmbed/index.
⚠️ Important: The restrict REST API option and CSP can affect integrations and plugins. Test it in staging first.
Privacy: the plugin does not send data to external services or create new tables. It only uses transients to count failed login attempts.
