Wide Area Network (WAN) is a communications network that spans a wide geographic area across cities, countries or regions. Connecting multiple Local Area Networks (LANs) from headquarters to branch offices, data centers and the cloud.
Traditional WAN was implemented via expensive MPLS leased lines from telecommunications providers, connecting multiple LANs together with routing policies to direct network traffic between locations.
Software-defined WAN (SD-WAN) is a modern approach to seamlessly connect locations over lower cost broadband internet rather than expensive MPLS leased lines.
SD-WAN has evolved to encompass elements of security and control usually associated with standalone point solutions like Firewalls, IPS, VPN, and URL Filtering. Gartner recently created a new category Secure Access Service Edge (SASE), which differentiates basic SD-WAN functionality of replacing MPLS with broadband internet, to that of delivering a wide area network service with all the security built-in.
SASE combines network security functions (such as SWG, CASB, FWaaS and ZTNA), with WAN capabilities (i.e. SDWAN) to support the dynamic secure access needs of organizations. - Gartner
