BunkerWeb vs Envoy Proxy

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.

Envoy Proxy is a free, open-source proxy for edge traffic and service-to-service communication in cloud-native and AI-native applications. It runs as a self-contained process outside the application and can serve software written in different languages. Envoy handles HTTP/1.1, HTTP/2, gRPC, and HTTP/3, with HTTP/3 documented as alpha. Traffic features include routing, retries, circuit breaking, rate limiting, request shadowing, and outlier detection. It exposes subsystem statistics, an administration interface, and distributed tracing through third-party providers. Security features include TLS, JWT, role-based access control, and OAuth-related authorization and authentication. Operators must configure protections such as watermarks, overload management, and circuit breakers for availability resilience. Installation options include Docker images for amd64 and arm64, macOS Homebrew, and static binaries. Its API is compatible with Envoy Gateway and Istio.
