A New Approach to Enterprise WANs & Security

Enterprise WANs have traditionally used MPLS and single function CPE for connectivity and security. The result continues to be high cost and inflexible architectures, slow responses to service change requirements, and difficulty in deploying and managing proprietary hardware.

By transitioning from purely MPLS and single function CPE to SD-WANs and software-defined security (SD-Security), enterprises can harness a more DevOps-oriented approach to delivering WAN and security services, reducing TCO significantly while increasing IT agility.

To make this WAN and branch network transition achievable, Versa has created a comprehensive solution for SD-WANs and SD-Security that runs on commercial off-the-shelf (COTS) hardware, and that is open and fully programmable.

Improve WAN Costs & Performance, Increase Branch Security

Up to 80% lower TCO

By standardizing on Versa VNF software and commodity hardware – instead of proprietary networking and security appliances – customers can slash their infrastructure Capex spend.

Customers can significantly lower their Opex by reducing or eliminating branch office truck rolls, shortening help desk and troubleshooting time, and easily integrating new services into existing deployments. Usage-based pricing ensures customers only pay for what they use.

IT agility – deploy in hours vs. weeks

Versa enables customers to roll out large-scale SD-WAN and branch security deployments quickly and without complex or proprietary hardware.

As a result, new deployments can be designed and validated in days. Network IT teams can adopt an agile, software-based DevOps model and remove the provisioning time and hardware dependency of traditional WAN and security architectures.

Improve performance & security

Versa solutions automatically identify over 2500 applications and assign the appropriate WAN access technology based on business policies. The result is better application performance and lower overall WAN costs.

For stronger branch security, additional security functions can be applied to traffic using direct Internet access, while MPLS traffic may not require it.

Simplify support & operations

With zero-touch provisioning and centralized management, IT teams can significantly reduce the time required to manage networking and security services at the branch, resulting in up to 50% opex savings.

In addition, Versa Analytics ‘big data’ analytics software provides customers with deep visibility and real-time intelligence into all networking and security functions to further simplify ongoing operations.

Use Cases for Enterprise


For large enterprise customers that are interested in the benefits of SD-WAN, but require a very scalable architecture and full routing and security from the branch office, Versa provides a highly elastic, resilient and SD-WAN solution. Versa SD-WANs are multi-service and include a range of software-defined security functions.


For enterprises looking to increase security at branch offices, Versa virtualizes and integrates multiple functions into an easy to manage software-defined (SD) security solution. Functions can be deployed locally at the branch (e.g. next-gen firewalls and URL filtering to enable direct Internet access), centrally at the corporate data center, or a hybrid combination as business needs require.
