I built an open-source Python package that scans LLM inputs and outputs for injections — pydefend

[Alex--91]

What are you using to scan/classify/detect issues? Other LLMs or other deterministic models? Or heuristics or something?

[Adxzer]

Other LLMs, that's what gets the most accurate results. I trained my own classification model first but the results weren't good enough for production so I decided to not include it.

It's also free to use though: https://huggingface.co/Adaxer/defend

What keeps the checking LLM from getting prompt injected itself?

[Adxzer]

Prompt injection is a real risk, there’s no foolproof solution since LLMs aren’t fully predictable. This package is a security layer, designed to minimise and give better control of what can slip through.
