prompt-shield is positioned as a defensive guardrail against prompt injection, a class of attack defenders increasingly need to filter at the middleware layer before requests reach an LLM.
The GitHub repository JustiNoel/LLM-Prompt-Injection publishes 'prompt-shield', a Python middleware that sits between the user and an LLM to inspect input before output is produced, packaged with Docker Compose for deployment.
