Open-source tools for LLM prompt injection testing compared

By PulseAugur Editorial · [1 sources] ·

Several open-source tools exist to test LLM applications for prompt injection vulnerabilities, but they are not interchangeable and cater to different testing needs. Promptfoo, Giskard, and sentinel-scan-cli focus on app-layer testing, evaluating the application's prompts and logic, with Promptfoo being widely adopted and used by companies like OpenAI and Anthropic. Garak, maintained by NVIDIA, is a model-layer tool that tests the underlying model's susceptibility to attacks independently of the application. Microsoft's PyRIT, now archived, offered multi-turn attack orchestration for both app and model layers. AI

IMPACT Choosing the right prompt injection testing tool is crucial for securing LLM applications and avoiding costly vulnerabilities.

    How to test your LLM app for prompt injection: promptfoo vs garak vs Giskard vs PyRIT vs sentinel-scan-cli

    <p>If you're shipping anything with an LLM in the request path (a support bot, an agent that calls tools, a RAG pipeline reading untrusted documents) you eventually have to answer "did we actually test this for prompt injection, or did we just eyeball it." There are a handful of …
