AWS Bedrock Guardrails Explained for LLM Safety Enforcement in Node.js

AWS Bedrock Guardrails are server-side rules that filter harmful or non-compliant content from large language model outputs. They can block categories like hate speech, personal data, or custom policy violations before responses reach users. Developers can define these rules via a console interface and attach them to specific models using an ARN identifier. Implementing guardrails helps maintain user trust, ensures regulatory compliance, and controls processing costs by preventing rejected outputs.
