BunkerWeb vs Security Ninja

BunkerWeb is an open-source web application firewall and NGINX-based server that protects web services as a reverse proxy. Its core protections include HTTPS with automated Let's Encrypt, HTTP security headers, TLS hardening, ModSecurity with the OWASP Core Rule Set and automatic bans for suspicious behavior. It can block known malicious IPs through external blacklists and DNS-based blackhole lists. Bot challenges can use cookies, JavaScript, CAPTCHA, hCaptcha, reCAPTCHA or Turnstile. Supported deployment integrations include Docker, Docker autoconf, Swarm, Kubernetes and Linux. An optional web UI manages instances and configurations, though it is currently supported with Docker and Linux integrations. The open-source plan costs nothing under the AGPLv3 license. A PRO version has pricing based on the number of protected services; Standard has no technical support, while Enterprise includes dedicated technical support. Kubernetes Gateway API mode is in beta. For API access, the documentation recommends an IP whitelist and optionally an API token. Free community support is available through Discord, GitHub Discussions, Reddit, Server Fault and Super User; professional support and consulting are also offered.

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.
