About PromptGuard

The firewall for AI prompts.

We built PromptGuard because traditional security doesn't work for LLMs. Everything is potential instructions. A user typing "ignore previous instructions" can override your system prompt. There's no syntax error to catch, it's just text.

So we built a firewall designed specifically for AI. It analyzes requests before they hit the model, detects malicious intent, redacts PII, all with zero code changes. Just swap your base URL.

AI security needs to be infrastructure, not an afterthought. Every company building with LLMs needs this layer. We're making it simple.
