The NIS2 24-Hour Clock Is a Telemetry Problem: An Executive Brief
A short, executive-level take on Europe's NIS2 24-hour clock and the one technical prerequisite the directive makes load-bearing: streaming telemetry on a supply chain a regulator can audit.
Europe’s NIS2 Clock Is Already Ticking: Why Your Five-Minute SNMP Poll Won’t Make the 24-Hour Deadline
Europe's NIS2 directive starts a 24-hour reporting clock on incident awareness. Polled SNMP burns that budget before your NOC ever sees the event. Why a streaming telemetry plane, not another dashboard, decides who survives the directive.

Why Service Providers Are Deploying Open Networking: 5 Drivers Behind the Shift
More than 100 service providers deployed open networking through IP Infusion in a single year. This article examines the five operational and financial drivers behind the accelerating SP adoption of disaggregated networking — from 5G infrastructure economics to broadband BEAD program requirements.
