THE CHANNEL MANAGER’S PLAYBOOK 6 Network complexities increasingly require SASE; the complexities of SASE require patience SASE’S SLOWROLL By Martin Vilaboy For increasing percentages of enterprise network decision-makers, the deployment of secure access service edge (SASE) is less about “if” and more a matter of “how.” Analysts at Gartner expect that by 2025, at least 60 percent of enterprises will have explicit strategies and timelines for SASE adoption encompassing users, branches and edge access, up from the 10 percent that had SASE in the works in 2020. Dell’Oro group, meanwhile, estimates the SASE market will grow at a compound annual growth rate of 116 percent, reaching a market value of $5.1 billion by 2024. Much of the expected rapid growth around SASE, which combines network and security into one framework that is software-defined and delivered through the cloud, can be attributed largely to the fact that corporate networks have grown increasingly diverse, dispersed and complex. As company resources increasingly reside in the cloud, and workers, devices and compute power increasingly move to the edge of networks, network security and access also must flexibly follow to the edge. “What once was a relatively straightforward equation of building a virtual moat around the network perimeter has become infinitely more complicated, given that the notion of the network perimeter, itself, has become obsolete in a borderless cloud-based environment in which almost anything can be delivered as-a-service,” said Ken Presti, analysts for Avant Research & Analytics, in a report on the state of SASE.
