A Software-defined Wide Area Network (SD-WAN) is a virtual WAN architecture that allows enterprises to leverage any combination of transport services – including MPLS, LTE and broadband internet services – to securely connect users to applications. An SD-WAN uses a centralised control function to securely and intelligently direct traffic across the WAN. This increases application performance and delivers a high quality user experience, resulting in increased business productivity, agility and reduced costs for IT.
Traditional WANs based on conventional routers were never designed for the cloud. They typically require backhauling all traffic – including cloud- destined traffic – from branch offices to a hub or headquarters data center where advanced security inspection services can be applied. The delay caused by backhaul impairs application performance resulting in a poor user experience and lost productivity. Unlike the traditional router-centric WAN architecture, the SD-WAN model is designed to fully support applications hosted in on-premise data centers, public or private clouds and SaaS services such as Salesforce.com, Workday, Office 365 and Dropbox, while delivering the highest levels of application performance.
An SD-WAN enables cloud-first enterprises to deliver a superior application quality of experience (QoEX) for users. Using intelligence and by identifying applications, an SD-WAN provides application-aware routing across the WAN. Each class of applications receives the appropriate QoS and security policy enforcement, all in accordance with business needs.
Secure local internet breakout of IaaS and SaaS application traffic from the branch provides the highest levels of cloud performance while protecting the enterprise from threats. Unlike SD-WAN, the conventional router-centric model distributes the control function across all devices in the network and simply routes traffic based on TCP/IP addresses and ACLs. This model tends to be rigid, inefficient and not cloud-friendly, resulting in a poor user experience.
Versa Networks enables enterprises to deploy a secure SD-WAN for their branch/multi-cloud networks while simplifying operations, improving network resilience and application performance. The solution integrates of critical security functions such as NGFW and Unified threat management (UTM) with the SD-WAN

Cloud interoperable solutions such as Versa are ideal with increase in the use of multiple cloud (IaaS), platform-as-a-service (PaaS) and software-as-a-service (SaaS) solutions. Versa allows you to determine how a specific app is performing to deliver deterministic and adaptive traffic conditioning optimized for each application
• Remove barriers legacy WAN and branch architectures place on strategic IT projects and business process improvements
• Make network an agile IT resource through a software-based approach that enables IT to rapidly provision new branch offices, dynamically add new network and security functions, and seamlessly scale capacity as required
• Deploying a new branch office network is simpler with zero-touch configuring through central management
• Zero-touch provisioning to deploy a fully featured set of Versa SD-WAN and branch security capabilities onto a single appliance
• Capex and Opex significantly reduced with Versa SD-WAN software, low-cost appliances, minimized hands-on time, and no hardware refreshes
• Branch security can be increased by adding security functions locally, in the enterprise data center, or a combination of the two
• Reduce WAN connectivity costs by seamlessly integrating Internet and broadband alongside MPLS which increases bandwidth and significantly reduces cost
• Versa SD-WAN carefully maps different applications across MPLS and Internet/broadband based on business policy and app-specific SLAs
• Lower overall WAN costs and higher performance through more bandwidth, direct cloud access and MPLS offload
Versa Networks Cloud Services Gateway (CSG) is a next-generation enterprise software-defined networking appliance that is based on Intel's x86 latest architecture to deliver cloud-native Secure SD-WAN. CSG700 series appliances are ideal for small and medium branch offices
Versa Operating System VOS™ comes pre-installed on the Versa CSG appliances and when activated using the Versa Titan Mobile App or Web Cloud Portal, the appliance will then attach to the customer network and the secure Versa Titan infrastructure and portal through the Versa ZTP process. The Mobile application is used to activate, monitor, configure and troubleshoot Versa Titan deployed branches
