The way people work has changed. Driven by the increasing use of cloud services and mobile devices, people now expect to be able to work at any time, from any place, and on any device. These changes are dramatically altering the network and security infrastructure in many organizations. Rather than staying with a legacy, hub-and-spoke network architecture, with offices interconnected over costly, dedicated links and remote users accessing centralized resources over VPN, more organizations are moving to a direct-to-web and direct-to-cloud model.
