SD-WAN is the product that addresses network segmentation issues and is comprised of Viptela and Meraki products. SD-WAN stands for Software-Defined Wide Area Network, which is a technology that simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. SD-WAN enables enterprises to use multiple types of transport services, such as MPLS, broadband, LTE, or 5G, to securely connect users to applications hosted in data centers or the cloud. SD-WAN also provides centralized visibility and control, dynamic path selection, application optimization, and security policies for the entire network.
Viptela and Meraki are two of Cisco's SD-WAN solutions that cater to different customer needs and preferences. Viptela is a cloud-first SD-WAN solution that offers advanced routing, segmentation, and security capabilities for complex enterprise networks. Viptela can be deployed on-premises or in the cloud, and supports multiple transport options, including cellular wireless. Meraki is a cloud-managed SD-WAN solution that offers simplicity, reliability, and automation for lean IT environments. Meraki can be deployed using plug-and-play devices, and provides easy configuration, monitoring, and troubleshooting through a web-based dashboard.
Both Viptela and Meraki products help enterprises address network segmentation issues by enabling them to create secure virtual networks that isolate traffic based on business intent and policy. Network segmentation improves network performance, security, and compliance by reducing congestion, preventing unauthorized access, and enforcing granular rules.
