Use this as a working checklist, not a brochure. Tick what you can today, schedule the rest, and revisit monthly. For config how-tos, see the hardening guide. For habits and routines, see best practices.

WordPress security checklist

HTTPS and transport

  • SSL/TLS certificate is installed and valid
  • HTTPS is forced site-wide (HTTP redirects to HTTPS)
  • Mixed-content warnings are cleaned up on key pages (home, login, checkout)

Core and updates

  • WordPress core is on the latest secure release (or scheduled to update soon)
  • Minor/security auto-updates are on if the site can tolerate them
  • Major updates are tested on staging when the site is critical
  • Plugins and themes are updated, or intentionally pinned with a reason
  • PHP is on a version your host still supports

Passwords, 2FA, and least privilege

  • Unique long passwords in a password manager for every privileged account
  • No shared “team admin” account
  • No user named admin if you can avoid it
  • 2FA enabled for administrators (editors too when possible)
  • Administrator role limited to people who need it (least privilege)
  • Editors/authors cannot install plugins or change settings they do not need
  • Former staff/contractor access removed

Admin and login hardening

  • Failed login limits / login protection on
  • Login URL rename considered (noise reduction only; still use 2FA + limits)
  • Production has debug display off (WP_DEBUG_DISPLAY false)
  • DISALLOW_FILE_EDIT is true (blocks theme/plugin editing in wp-admin)
  • File permissions are sane (no 777; tighten wp-config.php when the host allows)
  • Core files match expected WordPress copies (or differences are explained)

Remove unused software

  • Only plugins you actually use are installed
  • Unused plugins are deleted (not just deactivated)
  • Unused themes are deleted
  • No nulled / pirated “premium” packages
  • Vulnerability scan is clean (or findings are triaged)

Backups and recovery

  • Automatic backups run on a schedule (files + database)
  • Backups exist off the same server when possible
  • Retention covers “infection started weeks ago”
  • You have restored once (or watched someone restore)
  • Backup credentials are not only stored inside the site
  • You know who to call if restore fails (hire cleanup if that is you)

See backup plan.

WAF, scans, and monitoring

  • Cloud firewall / a WordPress firewall plugin is on if you have Pro (600M+ IP intel on Security Ninja Pro)
  • Malware scan scheduled or run regularly (and you know how to remove WordPress malware if something slips through)
  • Security tests reviewed after bigger changes
  • Events / alerts watched for odd logins and blocks
  • Search Console verified (helps catch Safe Browsing issues)
  • You open the site logged out occasionally (catches visitor-only redirects)

Hosting and access

  • Host provides restores you understand how to use
  • Support contact details are written down somewhere off-site
  • You know how to reach SFTP/SSH or the file manager if wp-admin dies
  • SFTP/SSH keys or passwords are strong and not shared casually

WooCommerce / forms (if relevant)

  • Checkout and login spam protections considered
  • Payment and shipping plugins are maintained
  • Form plugins are updated; spam protection is on

Suggested order (if starting from zero)

  1. Confirm backups
  2. Force HTTPS if it is not already
  3. Update everything; delete unused plugins/themes
  4. Fix admins, passwords, 2FA, login limits
  5. Turn on firewall + scanning if available
  6. Harden wp-config and permissions
  7. Run security tests and fix what is easy
  8. Set a monthly reminder and stick to it

Monthly revisit (10 minutes)

  • Updates pending?
  • New unexpected admins?
  • Last backup OK?
  • Any scan findings left open?
  • Events look weird?
