🛡️Vigil

⚡ Security scanner for Large Language Model (LLM) prompts ⚡

Overview 🏕️

Vigil is a Python library and REST API for assessing Large Language Model prompts and responses against a set of scanners to detect prompt injections, jailbreaks, and other potential risks. This repository also provides the detection signatures and datasets needed to get started with self-hosting.

• Repo: https://github.com/deadbits/vigil-llm

This application is currently in an alpha state and should be considered experimental.

Work is ongoing to expand detection mechanisms and features.

Highlights ✨

• Analyze LLM prompts for common injections and risky inputs

• Use Vigil as a Python library or REST API

• Evaluate detections and pipelines with Vigil-Eval (coming soon)

• Scanners are modular and easily extensible

• Available scan modules

  • Vector database / text similarity

    • Auto-update vector database with detected prompts

  • Heuristics via YARA

  • Transformer model

  • Prompt-response similarity

  • Canary Tokens

  • Sentiment analysis

  • Relevance (via LLM)

• Supports local embeddings and/or OpenAI

• Signatures and embeddings for common attacks

• Custom detections via YARA signatures

• Streamlit web UI playground
