WP Security Ninja walkthrough
Pro Cloud Firewall combines request filtering with a living blocklist of known bad IPs, country rules, and redirects, so most attacks never become a WordPress problem.
Brute-force bots love the default login page. Pro adds failed-login limits, a custom login URL, and two-factor authentication with authenticator apps or email codes.
Full events logging plus webhooks means failed logins, firewall blocks, and updates can land in Slack, Discord, or Zapier, not only inside wp-admin.
Free vs Pro
Free gives you real visibility and hardening. Pro is the complete protection layer most site owners need.
Forever free
A strong starting point for every WordPress site.
Recommended
