We built PromptGuard because we kept seeing teams ship AI features without proper security. Traditional security tools don'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. We've seen customer support bots leak internal prompts. Code assistants bypass safety filters. Document Q&A systems expose sensitive data. The problem is real, and it's happening more than people think. So we built a firewall designed specifically for AI. One that analyzes requests before they hit the model, detects malicious intent, redacts PII, all without requiring code rewrites. Just change your base URL. The response has been incredible. Companies are realizing they need this infrastructure layer, and we're here to make it simple. If you're building with LLMs, you need PromptGuard. What questions do you have? We're here to answer them.
