About Guardrails AI

Guardrails AI is an open-source framework for adding safety guardrails to LLM applications. It provides validators for output quality, format compliance, toxicity, PII detection, and custom business rules. Guardrails AI intercepts LLM outputs and automatically retries or corrects responses that fail validation.

Frequently Asked Questions

What are the main security risks with LLM applications?▾

The primary risks are prompt injection, data leakage, jailbreaking, and hallucination. Each requires different mitigation strategies.

Do I need a dedicated AI security tool?▾

If your LLM application handles sensitive data or is user-facing, yes. Basic input validation is not enough — LLM attacks are sophisticated and evolving. Dedicated tools stay updated against new attack vectors and provide defense-in-depth.
