Why it matters
AI guardrails are the front-line control against prompt injection and jailbreaks, yet documented evasion research shows they can be bypassed, so defenders must test rather than trust their guardrail coverage.
Mindgard's guide 'What are AI Guardrails' explains how input, output and agent guardrails defend generative AI systems and surveys the tools that enforce them (NeMo Guardrails, Guardrails AI, Llama Guard, AWS Bedrock Guardrails). The guide highlights peer-reviewed research (Hackett et al., LLMSec 2025) showing that six leading guardrail systems, including Microsoft Azure Prompt Shield and Meta Prompt Guard, can be bypassed with up to 100% evasion success.
