## What it is
The Symfony Security CSRF component provides a CsrfTokenManager class for generating and validating cross-site request forgery (CSRF) tokens in PHP applications. It is part of the Symfony framework's security ecosystem but can be used standalone.

## Use cases
- protect forms from CSRF attacks
- generate and validate CSRF tokens in PHP
- secure state-changing POST requests
- add CSRF protection to a non-Symfony PHP project
- validate tokens for AJAX form submissions

## When to choose
- you need CSRF token generation and validation in any PHP application
- you are building a Symfony app and need form security
- you want a small, well-maintained, MIT-licensed security component

## When to avoid
- you need full authentication or authorization, not just CSRF protection
- your framework already bundles CSRF protection
- you are not working in PHP

## Facets
- artifact type: library
- maturity: stable
- function: security, middleware
- domain: security, web-development, backend
- platform: php
- tags: csrf, symfony-component, token-generation, token-validation, form-protection
