Most AI security tools inspect messages. Arc Gate inspects sessions.

Imagine you're monitoring an AI in real time — most tools only scan one message at a time, like checking each text in isolation. But as /u/Turbulent-Tap6723 points out on Reddit, that’s not how malicious prompts actually work. Attackers weave subtle nudges across multiple messages, emails, and web pages — nothing looks suspicious alone, but together they lead the AI astray. That’s why Arc Gate is different: it tracks the entire session, understanding the context shifts and the different sources, like prompts versus tool outputs, which shouldn’t all carry the same weight. By doing this, Arc Gate aims to stop agents from acting on hidden instructions buried in untrusted data. It’s a smarter, more nuanced approach. And honestly, this could be a game-changer for security — if others see the value in it. As /u/Turbulent-Tap6723 wonders, is this the way forward, or are existing methods already covering this ground? Either way, the shift toward session-aware inspection feels like a crucial step in defending AI systems from evolving threats.
