BunkerWeb vs Imperva API Security

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.

Imperva API Security brings API discovery, risk assessment, detection, and mitigation into one console for cloud, on-premises, and hybrid environments. It monitors public, private, and shadow APIs, tracks changes, and identifies design flaws and vulnerabilities. Ongoing assessments address risks associated with the OWASP API Security Top 10. For Broken Object Level Authorization, its machine-learning-driven detection profiles traffic for behavioral changes and can block exploits. A separate testing function scans uploaded API specifications for posture gaps, design and configuration weaknesses, and risky endpoints. Teams can choose cloud-managed or self-managed management, with agent-based or agentless deployment options for cloud WAF, microservices, encrypted applications, and network-layer monitoring. Integrations include Kong, Mulesoft, Azure APIM, Apigee, and F5. API sensitivity classification includes government IDs, card details, addresses, and other personal information. With Imperva’s application security platform, it addresses nine OWASP API Top Ten risks; Unsafe Consumption of APIs is not covered. It runs on API, self-hosted, and web platforms. Pricing is on request; there is no free plan, and a 30-day trial may be limited to 100 Mbps, with excess traffic potentially null-routed.
