WP Security Ninja

WP Security Ninja is a WordPress security plugin built for freelancers, agencies, and site owners who want practical protection without a second job managing security.

The free plugin includes an 8G-based firewall, vulnerability scanner for plugins/themes/core, 50+ security tests with one-click fixes, core file integrity checks, and a basic events logger. Install from WordPress.org and run the setup wizard to turn on sensible defaults in minutes.

Pro adds a cloud firewall with 600M+ known bad IPs and country blocking, advanced malware scanning, brute-force protection, two-factor authentication, rename-login URL, scheduled scans with email reports, a full events logger, WooCommerce hardening, webhooks, and white-label branding on multi-site licenses. MainWP integration helps agencies manage security across client sites from one dashboard.

Security Ninja has been actively developed since 2011 and is maintained by Larsik Corp.
