With the support of Aksentt IOS XE Software, Aksentt SD-WAN is a highly secure, open, programmable, and scalable cloud-scale architecture. With the Aksentt vManage console, an SD-WAN overlay fabric can be quickly set up. Use it to connect data centres, branches, campuses, and colocation facilities to improve network efficiency, speed, and security. Since it wastes bandwidth and introduces latency, the conventional model of backhauling traffic from branch offices to the data centre for thorough security inspection is no longer the best option. There is a significant need for a better method of sending traffic from branch locations to reputable SaaS and cloud-based apps directly over the internet while remaining compliant with organisational security standards. An SD WAN ensures constant application performance and resilience, automates traffic steering in an application-driven manner based on business intent, enhances network security, and streamlines the WAN design. A centralised control function is used by an SD-WAN to intelligently and securely direct traffic across the WAN to reputable SaaS and IaaS providers. As a result, user experience is improved, business productivity and agility are increased, and IT expenses are decreased. This also improves application performance.
