Hey Product Hunt! 👋 I'm the founder of SupraWall, and here's the honest story of why we built this. We were building AI agents in production and kept hitting the same wall: system prompts are NOT a security layer. They get bypassed, hallucinated around, or simply ignored when the context window fills up. One Amazon Kiro agent deleted 847 production instances — $47M gone. That's not a prompt problem. That's an architecture problem. Every team I talked to was stitching together 5–6 tools: Lakera for injection, Presidio for PII, HashiCorp Vault for secrets, custom scripts for budget limits... and still getting 200ms+ latency and probabilistic failures. So we built SupraWall — a deterministic middleware that intercepts every tool call BEFORE execution. Not after. Not probabilistically. Hard rules, outside LLM context, in 1.2ms. It's open-source. One line of code. It replaces 6 tools. 👉 Would love your feedback — especially from anyone building with LangChain, CrewAI, or Vercel AI. What security gaps are you hitting in production that we should tackle next? Star us on GitHub if you find this useful 🙏
