How to Choose a AI Security Tool
Key criteria to evaluate when comparing AI Security solutions:
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.
About NeMo Guardrails
NVIDIA NeMo Guardrails is an open-source toolkit for adding programmable guardrails to LLM applications. It provides a modeling language (Colang) for defining conversation flows, topic boundaries, safety checks, and fact-checking rails. Integrates with any LLM and supports both input and output validation.
What is AI Security?
Platforms focused on securing AI systems—prompt injection defense, content moderation, PII detection, guardrails, and compliance for LLM applications.

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.
