SPEED OF AUTONOMY

NEUS is the "Invisible Fence" for AI—a private coordination layer that enforces Policy-Based Access Control (PBAC).

Policy-Based Access Control

Every action is checked against predefined governance rules before execution.

Pre-Flight Verification

NEUS intercepts every x402 payment request and verifies it against a private mandate.yaml.

ZK-Integrity

The agent proves it followed its rules without revealing its internal prompt or sensitive procurement strategy.
