View BunkerWeb Open Source WAF Review View Wallarm API Security Platform Review

BunkerWeb Open Source WAF and Wallarm API Security Platform take fundamentally different approaches to web application security. Understanding your infrastructure and team capabilities will help determine which approach fits your needs.

Overview

BunkerWeb and Wallarm represent open-source simplicity vs commercial AI-powered security. BunkerWeb is a free, Docker-native WAF with a web UI, built on top of Nginx and ModSecurity CRS rules. Wallarm is a commercial API security platform that uses machine learning to automatically discover endpoints and generate protection policies.

The approach to rule management is the key difference. BunkerWeb uses traditional OWASP CRS regex rules that you configure through its UI. Wallarm learns your API's normal behavior and flags anomalies, reducing the need for manual rule writing.

BunkerWeb is ideal for teams that want free, self-hosted WAF protection with a modern interface. Wallarm is for API-heavy organizations willing to pay for automated discovery and ML-driven protection.
