Use the WP Security Hardening Checklist tool for a full checklist.
Add Security Headers
Headers like HSTS, X-Frame-Options, and Content-Security-Policy add strong browser defenses. Generate them quickly with the Security Headers Generator.
Harden the Login Layer
- Allowlist trusted IPs with WP Login Guard.
- Move the login URL using Login URL Obfuscator.
Protect Sensitive Files
Block direct access to wp-config.php, disable directory listings, and prevent PHP execution in uploads using the .htaccess Generator.
Monitor and Adjust
Hardening isn’t a one-time task. Watch your logs and tune rules as new abuse patterns appear. Use the Server Log Analyzer to spot spikes in 4xx and 5xx errors.
