Security Ninja review
A WordPress-focused firewall and security toolkit with a useful free tier.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Security Ninja is a WordPress security plugin for site owners, freelancers, and agencies that need firewall filtering alongside site security checks. It combines 8G-based request filtering, cloud IP blocking, vulnerability scanning, WordPress core integrity checks, malware scanning and cleanup, login protection, two-factor authentication, event logging, and scheduled reports. WooCommerce users also get checkout, coupon, and abuse protection, while integrations include Slack, Discord, Zapier, MainWP, and WooCommerce.
Its pricing gives smaller site owners a low-risk starting point. The permanently free plan includes basic firewall rules, more than 50 security tests, vulnerability and core file scanning, and a basic events logger. A 14-day free trial is also available. Pro starts at $119 per year for one site, equivalent to $9.92 per site per month when billed annually, and adds the cloud firewall, malware scanning, login protection and 2FA, scheduled scans, and priority email support. The 5-site plan costs $259 per year; 25 sites cost $599 per year and add white-label branding and agency workflows; 100 sites cost $1,699 per year with those agency features.
The strongest fit is a WordPress-focused operation managing several sites and needing repeatable security workflows. White-label branding, multi-site licensing, MainWP integration, webhooks, visitor logging, and email reports make the larger plans more relevant to agencies than to a single casual site owner. The main boundary is scope: Security Ninja works at the WordPress application or site layer rather than as a CDN or edge WAF. Organizations seeking broader infrastructure protection should look elsewhere, while WordPress owners and agencies wanting layered filtering, scanning, login controls, and WooCommerce safeguards have a focused option.
