WordPress Hardening Checklist

Check WordPress security items: login, updates, permissions and more.

WordPress powers more than 40% of all websites, which makes it the first target for automated bot attacks. Run it with default settings and you are exposed to brute-force logins, vulnerable-plugin exploitation, user enumeration and XML-RPC amplification out of the box. This checklist gathers the highest-impact hardening steps — from login security to file permissions, exposure reduction, backups and HTTPS — in one place.

As you tick each item, a readiness score (%) is computed in real time and shown as an OK / caution / risk status. Everything runs in your browser; your input and checkbox state are never sent anywhere. Use it before launching a new site or during a periodic security audit.

Why WordPress hardening matters

Most WordPress compromises start not with a zero-day but with neglected defaults and outdated plugins. Attackers brute-force /wp-login.php, harvest usernames via/wp-json/wp/v2/users, and scan for plugins with known vulnerabilities. Hardening is about shrinking that automated attack surface.

Core measures, in priority order

  • Login security: two-factor auth (2FA), login attempt limits and strong passwords give the best return.
  • Updates: keep core, plugins and themes current, and delete anything you no longer use.
  • File protection: block access to wp-config.php and set DISALLOW_FILE_EDIT to disable in-dashboard code editing.
  • Reduce exposure: hide version info, block unused XML-RPC, and stop REST API user enumeration.
  • Be ready to recover: automated backups and end-to-end HTTPS decisively limit damage when something goes wrong. Verify your response carries the right headers with the security headers check, and tighten your content policy with the CSP generator.

Permission baseline

As a rule of thumb, set directories to 755, files to 644, andwp-config.php to 640 or 600. Minimize directories the web server can write to, and never use 777.

Frequently asked questions

Is anything I enter sent to a server?
No. Your checkbox state and the readiness calculation happen entirely in your browser and are never transmitted or stored externally.
Does changing the login URL really make me safer?
It is not a fundamental defense, but it blocks most automated bot traffic, cutting log noise and brute-force attempts. It works best alongside 2FA and attempt limits.
Do I really need to disable XML-RPC?
If you do not use Jetpack, mobile apps or external publishing tools, disabling it is recommended. XML-RPC can be abused for brute-force amplification and pingback DDoS.
What does DISALLOW_FILE_EDIT do?
Adding define('DISALLOW_FILE_EDIT', true); to wp-config.php disables the plugin/theme code editor in the dashboard. Even if an admin account is hijacked, editing server code directly becomes much harder.
Is a single security plugin enough?
Security plugins help but are not a silver bullet. Real protection requires the fundamentals too — updates, strong passwords, backups and least-privilege permissions.
