BitNinja vs Security Ninja

BitNinja is a Linux server security suite managed from a centralized dashboard. Its scanner monitors web files and uses cloud AI analysis to detect malicious PHP, webshells, and backdoors, with automatic quarantine available. The web application firewall inspects HTTP traffic and blocks SQL injection, XSS, CMS exploits, and other suspicious requests before they reach websites. BitNinja says its Defense Network shares attack information across protected Linux servers to block malicious IPs. Listed integrations include 360 Monitoring, cPanel, Plesk, DirectAdmin, Enhance, ISPmanager, and REST API endpoints. The site lists compatibility with Apache, NGINX, LiteSpeed, OpenLiteSpeed, Ubuntu, Debian, AlmaLinux, Red Hat, CentOS, and VzLinux. Intended users include hosting providers, server owners, VPS operators, and shared or dedicated server operators. Pricing is freemium, with a free plan, a 7-day trial, and paid access from $8/mo. The VPS Free plan is free for up to 2 vCPU, up to 2 GB RAM, and up to 10 hosted users. BitNinja is headquartered in Debrecen, Hungary.

Security Ninja is a WordPress security plugin for site owners, freelancers, and agencies. It is designed to block bad traffic, strengthen logins, find malware and vulnerabilities, and send alerts. The free plan includes basic firewall rules, more than 50 security tests with repair 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, and login controls including failed-login limits, a custom login URL, and two-factor authentication by authenticator app or email code. Pro can send selected security events through webhooks to Slack, Discord, Zapier, or a custom HTTPS endpoint. It also adds WooCommerce protections against coupon guessing, checkout spam, and repeated store login attempts. White-label branding is included with licenses for 25 or more sites, and the product supports MainWP workflows. The 14-day Pro trial requires a card or PayPal and must be cancelled before it ends to avoid payment. Pro is a plugin license and toolkit, not a managed cleanup service. The free plan costs nothing; Pro starts at $119 a year for one site.
