Remote Work Tools Become Critical Infrastructure

In March 2020, the COVID-19 pandemic forced offices, schools, and universities around the world to move online almost simultaneously. Video conferencing, VPNs, cloud collaboration, and identity systems suddenly became critical infrastructure.

The load pattern was unusual because services experienced months or years of expected growth in days. Video platforms had to scale media servers and network capacity, while companies discovered bottlenecks in VPN concentrators and authentication systems designed for a smaller remote workforce.

The transition also changed security boundaries. Employees were accessing company resources from home networks and personal devices, increasing reliance on multi-factor authentication, endpoint management, and cloud services. Remote work did not introduce these technologies, but it stress-tested them at unprecedented scale.
