Security audit

Authensor Gateway

Security checks across malware telemetry and agentic risk

Overview

Authensor Gateway is a disclosed, instruction-only security gate that checks tool-call metadata with an external policy service before allowing risky actions.

Install this only if you want Authensor to mediate tool calls through its external control plane. Verify the control-plane URL, use a dedicated Authensor API key, understand that file paths and action metadata may be logged as receipts, and review your policy for high-risk patterns such as download-and-execute commands.

A marketplace skill that tries `curl | sh`, exfiltrates data via HTTP, or reads your SSH keys will be caught and either require your approval or be blocked outright.
