It does literally everything you're asking for though? The data is also kept on-device. SNMP is there. Log aggregators and log forwarding are there. Rolling up to a centralized controller is there. The vendor data lake is just one more option.

To be clear, this is a VPN interface that has to handle incoming connection requests and traffic. Exploits are super common here. The command injection happens to only work when telemetry is also enabled, for reasons I haven't seen explained yet, but it could just as easily have been SNMP.
