Guardrails

Guardrails for Amazon Bedrock lets teams define and enforce usage policies across foundation models without modifying the models themselves. One configuration can filter denied topics, detect and redact PII, block harmful or profane content, and flag hallucinated responses through contextual grounding checks, applied consistently to any model behind the same API. The key exam distinction is from system prompts: prompts instruct the model but a motivated user can override them via prompt injection or jailbreaking, whereas guardrails are a separate enforcement layer intercepting inputs and outputs independently of the model, making them a more reliable control for compliance-sensitive deployments.
