SD-WAN: Software-Defined Wide Area Network in Cybersecurity
First part spelled; WAN said as word ('wan', rhymes with 'on').
SD-WAN stands for Software-Defined Wide Area Network. A software-defined wide area network decouples network control from the underlying hardware to manage WAN connections through a centralized controller. SD-WAN tunes traffic routing across MPLS, broadband, and LTE links.
How SD-WAN Is Used in Cybersecurity
Security engineers configure SD-WAN policies to route sensitive traffic through encrypted tunnels. Architects integrate SD-WAN with SASE platforms to apply security inspection at the network edge. The technology reduces costs while improving performance for distributed organizations.
