Security Ninja
What it is
Security Ninja is a WordPress security plugin for site owners, freelancers, and agencies. It is designed to filter harmful traffic, strengthen logins, scan for malware and vulnerabilities, and send security alerts. The free plan includes basic firewall rules, more than 50 security tests with fix guidance, vulnerability and WordPress core scanners, a basic event logger, and an install wizard. The core scanner checks WordPress core files against official originals. Pro adds a cloud firewall with country blocking and custom IP rules, a malware scanner for suspicious code, failed-login limits, a custom login URL, and two-factor authentication by authenticator app or email code. Pro webhooks can send selected events to Slack, Discord, Zapier, or a custom HTTPS endpoint. Its WooCommerce protection rate-limits coupon guessing, checkout spam, and repeated store login attempts. White-label branding is included for licenses covering 25 or more sites, and the product supports MainWP workflows. Pro includes priority email support. The 14-day Pro trial requires a card or PayPal, has no signup charge, and requires cancellation before it ends to avoid payment. The maker describes Pro as a plugin license and toolkit, not a managed malware-cleanup service or cleanup SLA.
