Automated excerpt

We just published our first public benchmark for AgentGuard, the runtime we're building to secure AI agents in production. The honest version: our deterministic (regex) layer alone catches 91. 5% of prompt injection attempts with zero false positives, in under 2ms. Adding a ML layer pushes recall to 98. 1% — but the trade-offs are real: ~450ms latency, and a 33% false-positive rate on benign prompts that were deliberately worded to look like attacks.
