Prompt injection ends up being less about clever attacks and more about unclear boundaries. In practice, limiting what an agent can do at each step reduced risk more than trying to detect every bad prompt.

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.
