l USE CASE l E N T E R P R I S E Remote and mobile workforces have been commonplace for years. With the COVID-19 outbreak, organizations around the world suddenly needed to securely transition entire employee workforces to remote home offices. As a result, over the course of just a few business days, the use of Virtual Private Network (VPN) technology expanded from select remote users to entire employee populations. And overnight, VPNs became the lifeblood of today's business operations, critical to keeping alive commercial, government, and healthcare organizations. If your VPN isn't functioning, your whole business is offline. Issue The current situation with VPN usage has changed all IT operations from a centralized data center network to thousands of remote offices. The conversion to all-remote workforces using wide-ranging mobile devices to access business resources has led to quick saturation of VPN bandwidth. Beyond adding VPN bandwidth to cure the problem, IT teams now need to factor how the wide-ranging applications and services are consuming those resources - very quickly, they need to separate services essential to business from those that are now "nice to have." The NETSCOUT ® nGeniusONE ® Service Dashboard example provided in Figure 1 shows how quickly VPN bandwidth was consumed in the early days of the pandemic. Figure 1: This nGeniusONE, Service Dashboard view shows a clear spike in VPN utilization occurring in a three-day span, corresponding to the COVID-19 progression timeline.
