Agentic commerce, banking, healthcare. One receipt for every regulated agent action.

Detection is not delegation.

Knowing an AI agent touched a transaction doesn't prove it was allowed to. SYEN seals what the agent was told to do, what it was authorized to do, and what it actually did: one receipt, verifiable across every rail and every platform.

Models can't stop unauthorized payments. In independent benchmarking, 62.6% of social-engineering attacks triggered unauthorized payment requests across every model tested. A deterministic authorization check reduced them to zero. SYEN Comply is that check.
