Businesses today face new security challenges that were not imaginable a few years ago. Workers and applications are widely distributed, meaning there is no hard edge to the enterprise network. And there is a need to integrate a large number of devices (smart sensors, wearables, IoT devices, and more) that the business has no control over. As a result, traditional security approaches must be replaced with modern ones that converge networking and security. These developments are driving great interest in technologies, including SD-WAN and Secure Access Service Edge (SASE).
