LLM Guard is a Python library providing input and output scanners to secure LLM interactions, including sanitization, harmful language detection, PII anonymization, and prompt injection resistance. The project has been archived and is no longer maintained.

Use cases

• detect and block prompt injection attacks on my llm app
• anonymize PII before sending prompts to an LLM API
• sanitize user input before it reaches a chatbot
• prevent data leakage in LLM responses
• add a security firewall around ChatGPT API calls
• scan LLM outputs for toxic or harmful content

When to choose

• you need a ready-made set of LLM input/output security scanners in Python
• you want PII anonymization and prompt injection detection out of the box
• you are okay using an unmaintained library as-is or forking it

When to avoid

• you need actively maintained software with bug fixes and updated models
• you require support for new LLM providers or recent attack techniques
• you want long-term production support without forking
