## What it is
The OWASP Web Security Testing Guide (WSTG) is a comprehensive, community-maintained guide to testing the security of web applications and web services. It provides a framework of best practices and numbered test scenarios (e.g., WSTG-INFO-02) used by penetration testers and organizations worldwide.

## Use cases
- learn how to pentest web applications
- find a checklist of web app security tests
- reference standard test IDs in a pentest report
- prepare for bug bounty hunting on web targets
- train developers on application security testing
- build a security testing methodology for web services

## When to choose
- you need an authoritative, vendor-neutral reference for web application security testing
- you want standardized test identifiers to cite in security reports
- you are training a security team or learning penetration testing

## When to avoid
- you need an automated scanning tool rather than a written guide
- you are looking for mobile, network, or firmware security testing guidance (see other OWASP guides)
- you need executable test scripts or tooling

## Facets
- artifact type: learning-resource
- maturity: active
- function: penetration-testing, security, documentation
- domain: security, penetration-testing, web-development, documentation
- platform: cross-platform
- tags: owasp, appsec, web-security, pentesting, bugbounty, best-practices, guide
