Prologue: Invisible Intrusion, But Packets Don't Lie In the previous post, we discussed how to preemptively block attacks at the network perimeter against the zero-day threat triggered by Anthropic's Claude Mythos. The SRX AI-PTP (AI-Predictive Threat Prevention) examined at the time predicts unknown threats in real-time using only the first few kilobytes (KB) of the payload in an inline proxyless environment…
As a security manager, when is the most disheartening moment? It is the moment you hear news of a breach before the seals on all your policy documents have even dried, after passing an ISMS-P certification or external audit with an "unqualified" opinion that you spent months preparing for.
