The effects of the cloud on network and security transformation are undeniable. As the number of devices at branch locations grows and applications become more bandwidth-intensive, businesses are forced to spend more to accommodate demand.
Software-defined wide area networking (SD-WAN), an approach that uses commodity links and allows you to intelligently manage as well as control connectivity between branches and cloud instances, is now a necessity for distributed enterprises. According to Gartner, by 2023, more than 90% of WAN edge infrastructure refreshes will be based on vCPE platforms or SD-WAN vs. traditional routers. However, with its benefits, SD-WAN also brings many challenges, such as lack of security, unreliable performance, and complexity. When security is an afterthought, it tends to be either subpar or bolted on, introducing management complexity.
Software-Defined Wide Area Network (SD-WAN) is a technology that allows us to use less expensive internet services to create an intelligent and dynamic WAN, which helps lower costs and maximize application quality and usability. From Palo Alto perspective SD-WAN is not just a network service, it is network plus security service. In other word it is time to converge network and security services through Palo Alto SD-WAN.
