LLM Guard - LLM Security Tool

Open-source LLM Security Toolkit L Cloud Infrastructure

Basic Information

Product Description

LLM Guard is an open-source AI security toolkit launched by Protect AI, designed to scan LLM inputs and outputs for security and compliance risks. It offers 15 input scanners and 20 output scanners, covering comprehensive security detection from prompt injection to PII anonymization to toxicity filtering. LLM Guard can be deployed on any LLM, including GPT, Llama, Mistral, Falcon, and supports any LLM framework. It has garnered 2.5k Stars on GitHub.

Core Features/Characteristics

  • 15 Input Scanners: Prompt injection detection, PII anonymization, toxicity filtering, etc.
  • 20 Output Scanners: Sensitive data detection, bias detection, factual consistency checks, etc.
  • Prompt Injection Defense: Detects and prevents prompt injection attacks
  • PII Anonymization: Automatically detects and anonymizes personally identifiable information
  • Secret Detection: Detects sensitive information such as API keys and passwords in inputs/outputs
  • Malicious URL Blocking: Identifies and blocks malicious links
  • Bias Detection: Detects bias in model outputs
  • Data Leakage Prevention: Prevents sensitive data leakage through LLMs
