Most organizations used traditional hub-and-spoke network model for connecting branch offices with data centers.
Unfortunately, this type of network architecture is quickly becoming obsolete with the emergence of the hybrid, work-from-anywhere (WFA) workforce and much more distributed computing. The COVID-19 pandemic accelerated digital transformation and drove employees to work remotely, away from a traditional workplace, and many are now functioning like "branches of one" and hybrid work models.
This development means network edges have dramatically expanded. The shift from traditional enterprise perimeters to remote work and cloud adoption means users now need consistent networking and security performance from any location, on any device, using any access methodology. At many organizations, user productivity is suffering because traditional network architectures simply cannot fully support remote workers need to access cloud-based network resources. The practical need for consistent, high networking, security and computing performance across LAN, WAN, data center and cloud edges is a big reason why networking and security must converge to meet the needs of today's workforce.
