+
+.. NOTE::
+
+   For out-of-band processing, you can use asynchronous calls from your backend applications, API gateway, middleware, or any programmable data plane that can extract prompt content and send it to F5 AI Guardrails for evaluation. Both BIG-IP (using iRules) and NGINX (using NJS) are supported. For the purpose of this class, we will use Nginx with NJS to demonstrate out-of-band processing.
