Show HN: A Prompt-Injection Firewall for AI Agents and RAG Pipelines 7 months ago
Introducing SafeBrowse
A prompt-injection firewall for AI agents.
The web is not safe for AI. We built a solution.
The problem:
AI agents and RAG pipelines ingest untrusted web content.
Hidden instructions can hijack LLM behavior — without humans ever seeing it.
Prompting alone cannot solve this.
The solution:
SafeBrowse enforces a hard security boundary.
Before: Web → LLM → Hope nothing bad happens
After: Web → SafeBrowse → LLM
The AI never sees malicious content.
