Versa FlexVNF Review

Good security features, good GUI interface, and easy to deploy


What is our primary use case?

We are a service provider, and we provide WAN services to various enterprise clients. We were among the  first three CSP's to launch SDWAN services in India with the help of Versa. Later on, we adopted Cisco and Fortinet platforms.

What is most valuable?

It is very easy to deploy. The GUI interface is really good, and the security features are also very good. It is also stable and scalable, and their support is also good.

What needs improvement?

SASE is the next big thing that is coming up, and it needs to be developed in Versa. This is the only thing that needs to be adapted very quickly by Versa.

With the pandemic going on, I would like to see more features for working from home. They have launched Versa Secure Access (VSA), but it is currently immature. They need to tighten it up for work from home and SD-WAN concept.

For how long have I used the solution?

I have been using this solution for three-plus years.

What do I think about the stability of the solution?

I don't see any issues on the stability front. We have been using this product for three-plus years, and I did not see any issues related to stability.

What do I think about the scalability of the solution?

It is pretty much scalable. Currently, it is on around 5,000 of branch location, and I don't see any problem on this front. We are providing services to enterprise customers, and we will be increasing the capacity of Versa.

Currently, approximately 1,000 plus employees regularly use Versa for various teams , and perform actvities such as  as deployment, assurance life cycle management, engineering, and PoC.

How are customer service and technical support?

There are no issues with their support. Their  TAC support is very good at identifying and resolving problems. 

How was the initial setup?

When you try to build a headend, it is a little bit complex, but after you are able to do that, it is a bit better and straightforward. In terms of duration, Versa headends in HA mode generally require four weeks. For Versa branches, you can do zero-touch provisioning.

What's my experience with pricing, setup cost, and licensing?

While Head End deployment is at par with other SDWAN providers the branch deployment is is not very expensive because of the white box support. White box hardware  is much cheaper than other products. Apart from White boxes you also flexibility to use Versa Boxes , In My opinion  it is one of the  cost-effective platforms that are currently available

Which other solutions did I evaluate?

When we were trying to implement SDWAN four years ago, the engineering team had evaluated many products. One of them was Cisco iWAN, which was later changed to CISCO Viptela. We evaluated Versa because of the white box and x86 support, which is a special feature. We went ahead with Versa because Cisco iWAN was not a stable platform at that time. Later on, we have added Cisco, Fortinet, and other SDN platforms. There are loyal customers of each and every solution or platform. 

Versa is good for medium and large enterprises. If you want SD-WAN for small enterprises, Fortinet is good. Fortinet is ahead of Versa in terms of ease of deployment. It has controller-less architecture.

What other advice do I have?

I would advise others to just go through all the documentation for its implementation. Versa has a huge repository for documentation. It is not that tough. Just go step by step, and you will be able to do it. If you miss one or two steps, it can get quite difficult to troubleshoot and implement it. That's why I advise following Versa documentation step by step.

I would rate Versa FlexVNF a nine out of ten.

Which deployment model are you using for this solution?
