My advice is that a person come with data that meets his needs, which would provide hima good basis for selecting the correct sizing.  

I rate Versa FlexVNF as an eight-and-a-half out of ten, owing to the issues concerning the size of the box configurations and licensing. But, this rating also reflects the flexibility of choice afforded by the solution, as well as its futuristic approach that allows one to upgrade it to the next level of technology. It is very close to the next level of technology and one can actually upgrade his solution anytime over the cloud and to the central processor without the need to visit the field. That's simplicity.

I would rate it 7 out of 10.

My recommendation of the solution to other users would purely be based upon the requirement of the users. If they are getting their requirements fulfilled, they can use the tool. Sometimes, I have seen users not wanting it for the connectivity facility it provides but for security.

I rate the overall solution a seven out of ten.

In our organization, we lend support to almost 300 different customers. This is in contrast to Fortigate, in which the number we are talking about involves 100 customers. 

We do not use the product. We are its providers. 

I would definitely recommend this product to others. An SD-WAN solution is appropriate for everybody. 

I rate Versa FlexVNF as a six out of ten. 

I rate this solution a nine out of ten. Versa is more suitable for customers who have large deployments because it doesn't compete well with the products suitable for small to medium customers. So they have a different product called Titan, and it's suitable. The solution is better for customers who have medium to large deployments.

Overall, I would rate Versa FlexVNF at eight on a scale from one to ten.

We're a Versa partner.

I don't recall which version we are using. 

I'd rate the solution nine out of ten.

I would recommend a field test to new users. Don't just look at the paper. Try to experience it in the live network. Most of the time, that could really make a difference. If customers would like to know about it, the better way is to have a proof of concept or live demo in their network running for a certain period, with their network running on top of this SD-WAN as that's what really actually makes the difference. They could see the improvement firsthand. They could see that the bandwidth is increased. Or find out if it really could replace the MPLS with the internet. Those are the things that on paper, sometimes we could not really feel or know. 

You could pick Versa if you're looking to replace all of your infrastructure on-site. It is very effective if you want to consolidate your firewall, analytics, and all that kind of stuff into a single box. It's got a great firewall that's built into there. It does most of the stuff that you need, such as built-in DDoS mitigation. It ticks many boxes for people who don't necessarily have the capability to do that. It is cost-saving instead of taking a separate DDoS protection or buying a firewall if you're looking at a dual hundred-meg type solution. The box probably won't cost you more than £150 a month at maximum, so that's incredibly affordable versus a full-state firewall because everything comes built-in.

Versa is good when you have a heavy branch when building office infrastructure. On the flip side, that's where I'd suggest VMware. If you have one or two main offices, and most people otherwise work remotely, or you have some small overseas sites with five people or something like that, that's where VMware comes into its own.

We're just a customer. We aren't a consultant or reseller.We have a couple of different models. We have the smaller models and the medium-sized models, however, I'm unsure of the exact model numbers.

New users should be aware of sizing. Making sure that the size is correct is important. There are small, medium, and large units, however, the smaller units only support certain functionality. In saying that, they seem to have some issues with some of the functionality on the small units not working. It's best to get a medium-sized unit to get some of the next-generation firewall stuff.

I'd rate the solution eight out of ten.

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.

We always propose only Versa solutions in our quotes for our customers when we have a new project. I only recommend Versa. VeloCloud was the first one to market and for customers that is very important. Customers ask me for a comparison between VeloCloud and Versa since VeloCloud was the first one on the market and he wants to be sure that if he goes with Versa it will not be a mistake.

For me it's not enough just to be first on the market. I know Versa, but I know it's not enough. VeloCloud solutions are more public for companies and buyers than Versa is.

These are the only two products that we validate that are in the regular network - Advantec and them.

On a scale of 1-10, where one is the worst and 10 is the best, I would rate Versa Flex an 8.

It is not a ten because it has a lot of features on the equipment and it is really heavy on the portal. It's not really friendly. Maybe they could do something different for users or administrators to have a friendlier portal.

We are a customer and an end-user. 

I was in a different company before working with SD-WAN before. This is a new company for me. We don't have live customers yet. 

If you're going to start using it, it's best to pick up a feature at a time and follow the documentation carefully. Try to configure it yourself and understand what's happening exactly. It's just a lot of hands-on work that really helps to understand what is going on with Versa with the CPE. That's how I learned that solution. 

I'd rate the solution eight out of ten. 

Overall, on a scale from one to ten, I would give this solution a rating of ten.

We have a lifetime implementation. We're using the latest version of the solution.

It's a good product for high-end and large enterprises, but smaller enterprises might not be a good fit.

I'd just advise that especially surrounding the initial setup, a new company needs to ensure they have the right support in place. Companies need to make sure their SLA's are very clear so they can get the support they need from the outset and into the future. Compare companies and be clear about the requirements and you will have an easier time.

I'd rate the solution eight out of ten. I'd give it full marks, however, I do believe that they can continue to improve on the existing product in various ways. 

I would rate it an eight out of ten. There's no brand that can rank a 10. A ten from my perspective, means good enough to ramp-up. Eight is the highest that can be scored amongst the choices of SD-WAN brands. I think the SD-WAN products Versa has have great space to improve. For example, automation. We are saying it's an SD-WAN solution, but it's not fully automatic for the service provider side. It requires a skilled managed service team to handle service delivery, even senior technical team involved.Their expertise is very important in customer solutions deploy and operation.

It takes a lot of manpower to go to market which is why I'm not fully satisfied. Also, currently, we have to treat the solution as an isolated direction to go with. If the customer has invested a lot in their network, like Cisco, Huawei, or even Juniper, the customer needs to abandon their current invest. In that case, we hope that Versa will allow the customer to leverage their current and past investments.

We're telecom operators and customers. We don't have a special relationship with the company and we aren't partners.

I would recommend the solution. I would also recommend that people have some specialists deploy and maintain it to make it easy to use.

I'd rate the solution eight out of ten.

Overall, I would rate the solution at a nine out of ten. We've been pretty happy with it so far. 

If you are trying to implement Versa Flex, I would recommend understanding how all the components work and stick together. You should know this because this is a next-generation technology using which you could deploy an orchestrator in other environments. You can then deploy your nodes on various sites, such as a physical site or a cloud environment, and control them from there. You should have good knowledge of how this technology works, and then you should appropriately use its new features, which segregate it from legacy routers.

It is a great product with good scalability features. It is good compared to other leading products in the market. I would rate Versa FlexVNF an eight out of ten.

I would give FlexVNF a rating of six out of ten.
