Excellent integration capabilities, good UI and offers great security features

Pros and Cons

  • "Overall, it's nice and very user friendly. That's what makes it so successful. They give you complicated features but with a very simple user interface, and that's been a big success for them."
  • "The support needs to be improved."

What is our primary use case?

We mostly implement this product for our clients.

What is most valuable?

There are many great aspects to the product. 

It's flexible. It's possible to have it on a universal CPE. The CPE is a small server or device that can be installed on the client's premises which the FlexVNF software can be installed onto. It doesn't have to be a vendor-specific CPE. This can help users reduce costs. Other solutions don't offer such flexibility.

One of the interesting things about the solution, which is not an easy feat, is that they offer a multi-tenancy solution at the CPE level.

They also allow for the integration of their solution as a provider with other security vendors, like Fortinet, Palo Alto, and Forcepoint. With other vendors, they stick with their own security appliances or images. This solution, however, really does try to integrate with everything.

In terms of support, they are very focused on SD-Wan technology. They are not working on multiple technologies. This ensures your business is very focused. It allows you to be very focused on your support and ensures your level of support will be very high. The customers will be satisfied with the results. 

The development is fast because they are only focused on one direction. Of course, SD-WAN not only means that you are optimizing the routing and the speed of the internet but also it allows you to optimize the security. Users can have better, more advanced security features. 

They are focusing on integrating their security features right now. They are growing quickly in this direction. That means they're giving a lot of attention to the security within the product. It's making it a more complete product without forcing you to just use Versa.

Overall, it's nice and very user friendly. That's what makes it so successful. They give you complicated features but with a very simple user interface, and that's been a big success for them.

What needs improvement?

The support needs to be improved. 

The interface does still need enhancements to make it even easier to operate in the future. They have complicated policies that need to be applied.

For how long have I used the solution?

We've been using the solution for about one and a half years now.

What do I think about the stability of the solution?

If the setup is done properly, the solution is quite stable. There's no need to worry about bugs and glitches. It doesn't crash.

What do I think about the scalability of the solution?

It is easy to scale. The solution has considered various roadmaps and focused on future growth for organizations. Some features may not be active just yet, however, they are in the roadmap.  They are looking at, for example, delivering Ethernet over two or three layers, over the internet, which is very interesting and is, in my opinion, revolutionary.

The solution benefits huge companies, more so than smaller ones. Currently, various product features are capable of fulfilling any big enterprise requirements. They are trying to get the certifications from international security communities like Gardner. Their focus is more so on the larger scale organizations and they are trying to compete with companies like Cisco, Palo Alto, etc. Since it is meant for bigger companies, it can get pretty big itself.

How are customer service and technical support?

Their support is okay, but they need to grow it out faster. They need a better mechanism for getting quick responses to clients and to hire more people on the support level. The gold standard is Cisco, and they should try to be more like that. 

They have a very focused product and because of that, they need a very focused support staff. They should have different people who are specialized on different aspects. They don't have to spend a lot of money to do this, they just need to ensure they have the right people in place to answer questions.

It seems a bit unfair to judge them in totality, however, as I just had one instance with them so far. 

How was the initial setup?

The solution's initial setup is complex in that it's not plug-and-play. You won't face zero-touch provisioning with this solution. Instead, there will be a staging process. It requires certain commands and you need to run it on Linux or Unix.

The solution has some issues with staging, and, if you compare it to other products, you'll see other vendors are much more straightforward. Zillow Clouds and Meraki are two good examples of a straightforward setup.

For myself, I have a technical background. These things are interesting for me, and I'm happy to do it, but on the commercial side of things, the customers don't really want to deal with difficult setups. Usually, however, it's the partner that provisions for the client, so the client never has to really deal with these issues. If you are a partner or a supplier, you'll end up doing this part yourselves. So, for those that know the product, it can be considered straightforward.

After that, users will enjoy a lot of features. 

It only takes about one hour to deploy the solution. I handled the POC myself and I've done some extensive training. I didn't feel comfortable in staging Versa devices. This was a problem. For comparison, if you would like to stage a VeloCloud device, it may take from you 10 minutes, whereas Versa could take about an hour.

If you are facing complications, you need to spend time understanding them before doing the provisioning. It will take some effort to understand the staging process, but it's worth it to take a step back. 

What about the implementation team?

I handled the POC myself and I've done some extensive training, so I was able to handle all the provisioning and staging. We found we struggled a bit with our engineers figuring out how to write everything correctly. Unlike other deployments where it's a very straightforward couple of clicks, if you make a mistake in provisioning there is a receipt required, and you need to call the engineer from your Versa vendor to help troubleshoot problems.

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

In the end, it's not only about cost. A lot of big enterprises don't care about the cost. They care about having a single point of contact to take care of their security and internet routing optimization. Having one support ultimately reduces costs, as there would only be one maintenance contract and one device.  

What other advice do I have?

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.

Very user-friendly and nimble software platform solution

Pros and Cons

  • "Their dashboard is also a good point for us and the customer. The solution is very clean and easy."
  • "Another thing that should be improved in Versa are their firewall features."

What is our primary use case?

We are using this product and also implementing it for our clients. We manage everything for the customer. We use it here on our platform and also manage the solution for our customers for whom we install it.

Let's say a customer is on premises and he wants to move to the internet but wants to keep the interconnection between their sites. He doesn't want to remain embedded. We would propose Versa in this case.

Also, if a client asks us for more reporting, more analytics and more monitoring and our embedded solution can't do this as a single solution because it would be very heavy and expensive, we would propose Versa. The client finds the analytics and monitoring in Versa very easy and very clear.

What is most valuable?

In terms of the most valuable features of Versa, I should know because I have also used Cisco, Fortinet and VeloCloud at a previous company where I worked. I explain that between Versa and VeloCloud I find that Versa has more features over VeloCloud. I do think that you have less regarding the firewall features compared to other solutions, though.

Their dashboard is also a good point for us and the customer. The solution is very clean and easy, but it depends what the customer has and how we can integrate it with their current network.

Another thing is regarding the analytics. We have about 15 sites in Europe, the US and Asia. I do some administration for the analytic portal, and this side is very interesting for the customer because today Versa has an embedded solution and we don't have the visibility for all the sites they're using.

What needs improvement?

In terms of what could be improved, I would say that since we're using more and more 4G today, the product should have two slots for 4G and also have the equipment for giga ready. It should not have different equipment to have a giga bandwidth. For example, it should have 110 and 200, 810 and 800. It would be good if they had only one product that goes directly to the bandwidth for one gigabyte and not necessarily to have different products to do it. Of course if I compare it to only one gigabyte, the price also needs to be reduced.

Another thing that should be improved in Versa are their firewall features. You have their firewall license secure solution but if they could include more features regarding their firewall protection and data protection it would be good. This is because when we go to a customer who also wants a firewall they compare it to other products on the market that are doing more with the firewall. As you know, Fortinet is very strong in this point. If they could put more features on this side, they can be, maybe not equal, but improved.

For how long have I used the solution?

Our company has been using Versa FlexVNF for around five years with our customers. Our network is on the ISP here in France and our AVN solution is only based on this product. 

What do I think about the stability of the solution?

It is stable. We haven't had any issues, and neither have the customers that already have it running for two or three years. They have stability on their end. The only stability issues are on the circuit and not on Versa's end. Sometimes the line is cut, so the customer will have an issue. But we don't have any issues with Versa.

What do I think about the scalability of the solution?

In terms of scalability, it doesn't matter if the company is large, medium, or small. We can use it for small and big companies - there is no limitation there. It is not always the company size that matters. When we go to a market segment and a big company, they may not know Versa at all. They may know VeloCloud better.

How are customer service and technical support?

I can say that I am satisfied with customer support but I'm not quite sure because it is my colleagues who manage this part of support. We have our technical support that manages Versa, the circuit, and all the vendors who are also on our platform.

How was the initial setup?

In terms of the initial setup, I can't answer that because I am just from the sales side, I don't do the installations, my colleagues do it. What I see from the customers that have installed Versa is that the initial step on the starting configuration is very easy. A half hour or hour. My colleagues who use it here in the company manage it and they have a full version for the configuration.

The issue that is difficult for us is when a customer needs firewall features included and he already has a firewall in place that he asks us to replace and to install the features from Versa. It is very complicated for us because it means more time to install since we need to export all the other features that already have rules in the firewall and to put them in Versa. That takes time.

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

Regarding the price, we can make do with its price today, but I am seeing from our competitors that this market is becoming very aggressive. We lost some projects because we didn't have any strategy to deal with the price. We think that when we discuss the quality of the product the price won't be an issue, so we do not propose it as "low-cost" for this reason.

Which other solutions did I evaluate?

Currently I propose Versa. That's the platform for my strategy. However, the market is not ready to propose a solution to a customer that's managed by an ISP. So, in the beginning they investigate VeloCloud, Cisco and Fortinet. But in the end they select Versa because it is small and easy for customers, and it has many features that are very interesting to the customers.

Today, when we look back, it was the right decision to choose Versa and our customers are very happy that we only propose this solution.

What other advice do I have?

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.

Straightforward with excellent next-generation firewall features and geo-blocking capabilities.

Pros and Cons

  • "The most valuable aspects of the solution are the next-generation firewall features and geo-blocking capabilities."
  • "The smaller units lack a lot of functionality."

What is our primary use case?

We primarily use the solution for multi-link aggregated circuits that are co-managed with our provider.

What is most valuable?

The most valuable aspects of the solution are the next-generation firewall features and geo-blocking capabilities. 

The high availability failover has been also been very important to our organization. Failover is when you have dual boxes and if one of them goes down, the other one picks up the traffic.

The entire solution is very straightforward.

What needs improvement?

The configuration is very much a command line. Some people don't like working with command lines. I don't know if this particular model can support it, however, if it had more of a GUI, I'd like to see that. It would be nice to see that they had a webpage to configure the solution on versus doing it as a prompt.

It would help if the solution offered artificial intelligence that can actually make real-time decisions on traffic flow.

The smaller units lack a lot of functionality.

For how long have I used the solution?

I've been using the solution for two and a half to three years now.

What do I think about the stability of the solution?

We definitely went over a few variations of the firmware. The initial firmware configurations had some issues, however, I think they've got it down now. I would say it's very reliable at this point.

What do I think about the scalability of the solution?

The solution is extremely scalable. We find that having a control center and being able to monitor in one location is very scalable. If organizations need to expand the offering, they can do so rather easily.

Everyone in the organization really uses the solution due to the fact that it's a network edge. Anyone who wants to get out of the network has to use the solution. If you're looking at it from that point of view, if you're looking at it from how many people within the organization actually deal with the daily grind of monitoring and keeping up, we have a small team that takes care of it. The team contains anywhere from five to ten people at any given time.

How are customer service and technical support?

Technical support has been responsive. This has been a co-managed implementation so when there are any high-end technical caveats, the provider has to deal with the back and forth with Versa. It hasn't been a first-person type interface with them. That said, when I've seen questions being asked, I've seen their responses, and they've been quick to help and reply.

How was the initial setup?

I helped with the initial setup.

It was not straightforward. It was definitely complex. Especially since it was a new product for us. We had a big learning curve from the get-go. 

Other than that, though, once you understood the setup, although I wouldn't say it was straightforward, it wasn't that difficult.

Implementation was over a six month period. We had to swap out upwards of over 35 different sites. We had to schedule downtime and switch out our infrastructure to support it and then bring it back up. Each side had to be done one at a time, without losing business continuity. It was a bit tedious. 

There was a lot of strategy and preparation that went into the project before we even began the setup. You can only take a site down for a certain amount of time without interrupting people's flow. However, our goal was to keep business as usual at up to 90% so that our clients didn't really notice the changeover.

What about the implementation team?

The deployment was co-managed with our providers. The provider brought in support and they had the expertise on the product itself. With their assistance, we strategized and came up with configurations. Then we worked out a schedule and came up with an implementation plan. We started the implementation and checked off each site one at a time as we went through.

What was our ROI?

Our original network diagram had single circuit MPLS network. And if that circuit went down, the site was down. So this network uses IQ circuit and a broadband circuit for the most part to aggregate and give you greater speeds.

We went from a single circuit MPLS to dual circuits. Therefore, between the cost of one circuit and then two circuits, the one circuit was an expensive circuit. The two are less expensive, but they kind of matched. So the pricing with the service, the new service add on that we did with the provider versus what we had, where it was a self-managed, kind-of washed out. I can't say that we really saved money, however, I don't know the full balance sheet all the way from top to bottom.

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

I'm not sure what the pricing is on the solution. We're looking at a variety of options, and we're looking to choose a technology and then push forward with a proof of concept as well as a pricing model. We're not there yet.

Which other solutions did I evaluate?

We are looking at other options. The implementation that we're looking to go forward with is going to be more app-centric based networking. We're looking to see if we can try and bring in something that is not too technical.

There are a few different SD-WAN providers that monitor what's called S-flow data and will take your traffic and balance it depending on what's happening in real-time versus just a straight "here's your internet circuits and use whatever you can" type of setup. As an analogy, if you are in a car, going from A to B, you can use an app like Waze that can warn you about traffic and can reroute you so that you get from A to B in the shortest time. That's what we're looking for. CloudGenix or Palo Alto Networks have SD-WAN solutions that not only aggregate your circuits but can actually push certain traffic certain ways on those circuits, depending on if you're being bottlenecked or if there's an over-bandwidth usage issue. Basically, what we're looking for is something that manages the flow of traffic better.

What other advice do I have?

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.

A flexible, stable and scalable solution

Pros and Cons

  • "The flexibility is a great feature."
  • "Future releases should contain AI for the voice feature."

What is our primary use case?

We use the solution for SD-WAN as well as SD-WAN plus security NGFW, UTM. We use the combination of these three as they relate to multi-sites. 

What is most valuable?

I especially like the flexibility of being able to choose the license based on customer application requirements. Also, when it comes to the hardware, certain support or different switches will apply. However, the software's flexibility does come with a price for the customer. There is flexibility when it comes to upgrading to a higher bandwidth or license, as well as when combining with the security solution, NGFW and UTM. 

To sum up, the flexibility is a great feature. 

What needs improvement?

I don't have issues with the hardware, as the requisite capacity is visible in the data sheets. All the details in the data sheets are accounted for. But, I find myself confused when it comes to combining this with the software. I have not come across documentation on the Versa website which would provide information about the parameters for selecting the appropriate license. For this we are assisted by the solution's design engineer and the Versa team. I do what I can as a project manager and make the best suggestions I am capable of concerning the competition. 

Future releases should contain AI for the voice feature. SSL VPN is lacking in the solution. I wish to see this in the near future. 

For how long have I used the solution?

I have been with Tata Communications for approximately two years respect this product. I have made a good contribution to the onboarding of Versa FlexVNF and the development of SD-WAN products in Tata Communications. As I have been working with Spectra on the same product, I can say that I have been doing so with the solution for this length of time. 

What do I think about the stability of the solution?

I have not encountered bugs in the solution. 

What do I think about the scalability of the solution?

I have not come across limitations in the solution. I have worked on the 300 series, the 700 series and the 1000 series, but there are no limitation within the box. The important thing is that the combination of the box and the license provide the correct solution. That's what comes with this. Otherwise, we must consider the hardware and configuration details in respect of the throughput authorization when it comes to 100 Mbps for NGFW or 400 for UTM. These are especially present in terms of the configuration of the box against the bandwidth.

How are customer service and technical support?

As I am in product management, I have not had occasion to contact technical support. This would be in the purview of team delivery, support, provisioning or engineering teams. Occasionally, technical account managers also provide assistance. 

How was the initial setup?

The installation process was complex. Templates are there and we can pretty much put those straight into the Versa director and push them for other sites. A single template spokes other templates. This would involve a change in bandwidth or configuration. We make the changes on the template and push for those particular sites. So, when it comes to Versa director and analytics, it's pretty simple.

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

While I cannot provide too much commentary on the price, I feel it to be fair for the moment. 

I should note that Citrix or Cisco Meraki are coming out with more competitive prices. The comparative pricing can pose an issue for us, as we are the ones who supply the solution. While we make adjustments to the solution, the majority of our customers have right templates and feel that they are able to get the same SD-WAN solution that fulfills our requirements for, perhaps, a price of 20 to 30 percent less than what we provide on Versa. 

What other advice do I have?

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.

Can easily be scanned or installed in a virtual environment and has good stability

Pros and Cons

    • "We are thinking about how to make customers consolidate the loads to an SD-WAN network so that the customers can have bigger chunk from the SD-WAN side so that customers can have critical data be transferred with NPS VPN and non-critical data or some labeled traffic can be transferred by the SD-WAN network. I think it's a very important direction for digital transformation."

    What is our primary use case?

    It's a purely internet-based solution. That means the customer already has their Ownned up-link(s), which we call DIA(Direct Internet Access). That means the customer brings their own connections to set up the virtual SD-WAN network and just use our white-box solution. On top of it, we set out an SD-WAN appliance which can be controlled by the setup on the CTG side.

    How has it helped my organization?

    Versa FlexVNF helps customer uses existing infrastructure to quickly complete the SD-WAN deployment through software appliance. Except for the edge hardware equipment used in customer case(s), SD-WAN provider no need invested in any hardware inside, but completely uses the existing Cloud platform.

    What is most valuable?

    Versa FlexVNF supports multi-tenancy, which is very important for ISP's TCO in running a SD-WAN network. Meanwhile,Versa FlexVNF is purely software based solution that help CSP(cloud service provider) upsell SD-WAN business.

    What needs improvement?

    We need to think about how to leverage the MPLS-VPN customers, so to integrate the SD-WAN network. We are thinking about how to make customers consolidate the loads to an SD-WAN network so that the customers can have a bigger chunk from the SD-WAN plane.Under the trend of Digital Transformation, enterprise customers looking for lower price with border bandwidth. In the designed direction,customers can have critical data be transferred by MPLS-VPN network while non-critical data or some labeled traffic can be transferred by the SD-WAN network. Considering the uncertainty of the economic situation, perhaps more companies will seek to expand data pipe based on the original network instead of building a new network. For new business areas which requires more flexible contract term,and shorter provision time, SD-WAN integrated with MPLS-VPN would be a important direction.

    For how long have I used the solution?

    I have been using Versa since 2017. 

    What do I think about the stability of the solution?

    The stability has been quite good. It's a purely software-based solution, so it can easily be scanned or installed in a virtual environment. It's very adaptive to those environments.

    What do I think about the scalability of the solution?

    Good and stable

    How are customer service and technical support?

    It is generally stable but when we have trouble with deploying or configuration we encounter certain issues. Their support is helpful and they respond in a timely manner. 

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

    The price is consist of several aspects but it makes sense for the market.

    For the SD-WAN solution, it's not just the pricing for accreditations from the solution side. We need to combine the hardware and the connections, even managing service ourselves. Customers need to have a integrated solution from a skilled engineer team, but not just to judge if the solution providers are fair or not. But generally, when we compare with other brands, I think this solution is lean and agile.

    What other advice do I have?

    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.

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

    Pros and Cons

    • "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."
    • "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."

    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.

    Straightforward setup, good scalability features, and can be configured and managed from anywhere

    Pros and Cons

    • "The division of Control Plane and Data Plane is most valuable. It can be deployed anywhere, and you can control it and configure it from anywhere. This is one of the good features of this solution."
    • "I heard about them for the first time just before I started working on Versa. They do have blogs for information, but they could publicize more about the documentation and architecture. It doesn't seem to have that much exposure, and they should work on their customer base more."

    What is our primary use case?

    I am working as a network engineer, and I test the performance of virtual routers and other products. I work in a lab environment where we test the performance of these products. I have worked on Data Plane for Versa. We have a controller deployed, and we have different templates on it.

    What is most valuable?

    The division of Control Plane and Data Plane is most valuable. It can be deployed anywhere, and you can control it and configure it from anywhere. This is one of the good features of this solution.

    What needs improvement?

    I heard about them for the first time just before I started working on Versa. They do have blogs for information, but they could publicize more about the documentation and architecture. It doesn't seem to have that much exposure, and they should work on their customer base more.

    For how long have I used the solution?

    I have been using this solution for only six months.

    What do I think about the scalability of the solution?

    It is easy to scale if you know about the SD-WAN technology, and you have worked on a similar solution. It is similar to other SD-WAN technologies and components. If you are experienced in working with other SD-WAN products, it will be easier. If you don't have a clue about it, it will be a problem.

    In terms of the number of users, in my team, there are 15 to 20 people. We get a requirement, and then we work on it. For example, a customer has a requirement for Versa Flex to be deployed in their environment. Sometimes, there may be ten people working on it, and sometimes, there may be just two people working on it. It depends on a customer's requirements.

    How are customer service and technical support?

    Their technical support is good. We directly communicate with Versa if we have any issues or questions. Their response time is really good. 

    Our issues were related to some glitches. Some of our test cases were also not working fine. They helped with what we were doing wrong. In our test environment, we had different configurations, and they were pretty helpful about that.

    Which solution did I use previously and why did I switch?

    I've worked on Viptela's SD-WAN technologies.

    How was the initial setup?

    It has a straightforward setup.

    What other advice do I have?

    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.

    Excellent virtualization and routing features with good technical support

    Pros and Cons

    • "Our organization finds the application routing features extremely useful."
    • "The UTM features can be improved. It should offer better functionality."

    What is our primary use case?

    We primarily use the solution for connecting to other branches via SD-WAN tunnels. The solution is routing data via application area polices and deprecation tools. It's a mix of a firewall and prevention software.

    What is most valuable?

    Versa's virtualization features are very good.

    Our organization finds the application routing features extremely useful.

    What needs improvement?

    The UTM features can be improved. It should offer better functionality. 

    The features, overall, could be improved upon. There aren't in general, enough of them. It's my understanding that it's part of the roadmap, so we're likely to get some functionality in the future.

    For how long have I used the solution?

    We've been using the solution for about two years now.

    What do I think about the stability of the solution?

    The solution is quite stable. We've found it to be reliable. There haven't been any noticeable bugs or glitches. It doesn't crash.

    What do I think about the scalability of the solution?

    The solution is scalable. If a company needs to increase its capacity, it's easy enough to do so.

    We have about 500 users on the platform currently. Some of them are hosting on the VNF, and some them are hosting on the physical advisors. It's a mixed platform. Our team uses it on a daily basis.

    How are customer service and technical support?

    The technical support that the company offers is very good. They've been very supportive. We're satisfied with the level of attention they provide us.

    How was the initial setup?

    The initial setup was challenging for us. It was a little bit difficult because the customer interface had too much audio which made it challenging. Other than that, it was pretty straightforward.

    In terms of deployment, and how long it will take, it depends on the customer requirements. Sometimes it only takes 30 minutes, sometimes it takes an hour. It depends on the configuration.

    We have a team of about 16 people who help deploy the solution. You only need two people to maintain the solution once you have everything up and running. 

    What about the implementation team?

    We had both an internal team and an integrator that handled the implementation. If there was some aspect our team couldn't handle, like clustering or extending, we had the integrator come in and assist.

    What other advice do I have?

    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.
