A financial services company deploys a customer-facing chatbot on Amazon Bedrock. Compliance requires that the bot must never provide personalized investment recommendations (e.g., telling a user which specific stocks to buy), because the firm is not licensed to give individualized advice. However, the bot should still be able to discuss general financial education topics and explain how markets work. The security team wants a configuration that reliably blocks the intent of requesting personalized recommendations, even when users phrase it in many different ways. Which Amazon Bedrock Guardrails feature best meets this requirement?
