## What it is
OWASP WebGoat is a deliberately insecure web application designed to teach web application security lessons through hands-on exercises. It demonstrates common server-side vulnerabilities in Java-based applications and is intended for learning application security and penetration testing in a safe, legal environment.

## Use cases
- learn web application security hands-on
- practice penetration testing techniques legally
- test security scanners against a known-vulnerable app
- train developers on common vulnerabilities like SQL injection and XSS
- set up a security lab environment with Docker
- teach secure coding in classrooms or workshops

## When to choose
- you want an interactive, guided environment for learning web security exploits
- you need a deliberately vulnerable Java app to test tools like ZAP or Burp
- you are teaching or studying OWASP-style vulnerability lessons
- you want a Docker-based security training target that runs locally

## When to avoid
- you need a production or hardened application - WebGoat is intentionally insecure
- you want to test techniques against systems without authorization
- you need a non-Java vulnerable target or a real-world codebase to audit
- your machine cannot be isolated from the internet while running it

## Facets
- artifact type: learning-resource
- maturity: active
- function: security, penetration-testing, testing
- domain: security, education, web-development, penetration-testing
- platform: self-hosted, jvm
- tags: owasp, vulnerable-app, security-training, java, web-security, deliberately-insecure, docker, web-server
