Prompt Guard functions as a man-in-the-middle (MitM) proxy that sits between users and AI APIs

Automatically detects and blocks secrets such as API keys, passwords, and tokens before they reach AI language models

Open-source project available on GitHub that developers can implement to add a security layer to their AI API interactions

Addresses growing concerns about accidentally exposing sensitive information when sending prompts to third-party AI services
