AI reads everything.

The web is not safe for AI.

Modern AI agents and RAG pipelines ingest untrusted web content.

Webpages can contain hidden instructions that hijack LLM behavior — without humans ever seeing it.

⚠️ Prompting alone cannot solve this.

SafeBrowse enforces a hard security boundary.
