A WAF (Web Application Firewall) operates at the perimeter, analyzing traffic as it crosses between external networks and your internal network towards your web servers. The browser environment is a separate execution context that happens on your users' devices, completely outside your network perimeter. Once JavaScript code reaches the browser and begins to execute, it's operating in an environment that your WAF has no visibility into or control over.
