AI found the bug. Humans took the blame. Meanwhile, the internet went dark. The current global PHP crisis (php2shell) forced entire government and healthcare networks in Europe to literally pull the plug and go offline. Why? Because an AI discovered a remote code execution (RCE)…

Layer Zero telemetry shouldn’t require enterprise overhead to be presentable. When auditing network infrastructure, drowning in thousands of raw packet captures or standard octet-stream updates makes real-time analysis impossible. The gap isn't a lack of logging; it's a lack of…
