For years, IT teams had a fairly contained job: keep the office network running. Every device, router, and switch that mattered was inside a building they controlled. That job doesn't exist anymore. Remote and hybrid work moved the "network" into hundreds of living rooms, home offices, and coffee shops, none of which IT can see, configure, or troubleshoot directly. So when a help desk ticket comes in saying "the app is slow" or "my calls keep dropping," IT is left guessing. Is it the company's network?
