In a conventional network model, data and applications are typically housed in a central data center. To access these resources, users, branch offices, and applications establish connections to the data center through localized private networks or secondary networks. These secondary networks often rely on secure leased lines or VPNs to connect to the primary network. However, this traditional model struggles to cope with the complexities introduced by cloud-based services such as SaaS and the growing prevalence of distributed workforces. As more applications and data migrate to the cloud, it becomes impractical to route all traffic through a centralized data center. This need to adapt to the changing landscape has fueled the surging popularity of SASE., Cisco Networking provides intelligent network solutions for organizations to securely connect users, devices, applications, and workloads everywhere., 4.
