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.

See it in action:

Scans content before your AI Blocks prompt injection (50+ patterns) Blocks login/payment forms Sanitizes RAG chunks
