Show HN: A Prompt-Injection Firewall for AI Agents and RAG Pipelines

We built SafeBrowse — an open-source prompt-injection firewall for AI systems.

Instead of relying on better prompts, SafeBrowse enforces a hard security boundary between untrusted web content and LLMs.

It blocks hidden instructions, policy violations, and poisoned data before the AI ever sees it.

Features: • Prompt injection detection (50+ patterns) • Policy engine (login/payment blocking) • Fail-closed by design • Audit logs & request IDs • Python SDK (sync + async) • RAG sanitization

PyPI: pip install safebrowse

Looking for feedback from AI infra, security, and agent builders.
