PromptGuard
Description:
PromptGuard - AI Prompt Security is an AI-powered, drop-in "firewall" for LLMs that inspects and sanitizes prompts and surrounding context in real time—using heuristics, ML classifiers and LLM-based detectors—to block prompt injection, redact PII, and prevent data leaks before requests reach your model. It adds minimal latency (<40ms), provides tunable policies, logs and analytics, supports major providers (OpenAI, Anthropic, Google/Gemini, Groq, Azure), and is aimed at product, security and enterprise teams that need production-grade prompt governance and compliance.
A real-time prompt firewall that sanitizes inputs, blocks prompt injection, redacts PII, and prevents data leaks.
Note: This is a Google Colab, meaning that it's not actually a software as a service. Instead it's a series of pre-created codes that you can run without needing to understand how to code.
Note: This is a GitHub repository, meaning that it is code that someone created and made publicly available for anyone to use. These tools could require some knowledge of coding.
