SASE: Securing the Digital-First Enterprise In the last year, the very concept of the office environment—and how work, collaboration, and communication takes place—changed dramatically. Now that users work on devices and connect over networks that corporate IT does not control, security risks have grown massively. Users, data, devices, and workloads are distributed largely outside of the data center, and often not on the corporate network, demanding new approaches for security. “The increase in remote users and Software-as-a-Service (SaaS) applications, as well as more data moving to the cloud, has driven a need for a new approach to network security,” says GigaOm Analyst David Linthicum.
