Arc Gate is mathematically different from every other AI security proxy — here’s why that matters

Most security proxies check if a message looks malicious. Arc Gate checks if the conversation’s trajectory is drifting toward something dangerous.

The difference is fundamental. A Crescendo attack spreads across 8 turns — each message looks clean. Standard tools evaluate messages in isolation and miss it entirely. Arc Gate maps the session onto a geometric manifold and measures structural drift using Fisher-Rao metrics. When the trajectory curves adversarially, it catches it before the payload lands.

No other proxy does this. The framework is published, the benchmarks are reproducible, and the math is open.
