94.7%of malicious calls blocked by the Flash guard

Agent GovBench

Oct 2026

An open benchmark that measures whether guardrails actually stop a tool-using AI agent from being misused.

A Gemini Flash guard blocked 94.7% of malicious tool calls and flagged 0.4% of benign ones. Model Armor at MEDIUM: 29.8% and 27.1%, on 999 synthetic scenarios with the agent in the loop.

Agent Gateway governance was not tested. I didn’t estimate a number for it.

The record

Almost two years of production Java on AWS taught me to profile first and trust tests over confidence. Agent governance is where that habit is most useful now.
