Presales Technical Consultant - Enterprise and Cybersecurity at Westcon ME
Easy deployment, micro-segmentation, and scalable
Pros and Cons
- "VMware NSX offers some of the best features for security, such as micro-segmentation."
- "Despite being somewhat behind in the cybersecurity field, VMware should develop a cloud and a red team to continuously monitor for new malware and ransomware."
What is our primary use case?
The solution is primarily used for micro-segmentation for the security of virtual machines.
What is most valuable?
VMware NSX offers some of the best features for security, such as micro-segmentation. This feature allows us to define policies on a per-virtual machine basis. For example, if we have four virtual machines, we can have four different firewalls attached to each of the VMs. This allows us to monitor the traffic between each VM, as they will have to go through two firewalls or two IPs. This added layer of security provides a great benefit to those utilizing the solution.
What needs improvement?
Despite being somewhat behind in the cybersecurity field, VMware should develop a cloud and a red team to continuously monitor for new malware and ransomware. They must maintain their own cloud to do their own research, and send the resulting hashes or values to all customers using VMware NSX. This will ensure that each customer is regularly updated with the latest malware and ransomware hashes to keep their systems secure.
Web filtering is a good feature that I would like to have added to the solution.
I would like the ability to limit the bandwidth per virtual machine to ensure that I understand the throughput requirements of any application that is running. This way, I can be protected from the risks of a DoS or DDoS attack, which may require a high level of throughput. This limitation would apply to Layer 4 or Layer 5 of the network.
For how long have I used the solution?
I have been using the solution for three years.
What do I think about the stability of the solution?
VMware NSX is stable.
What do I think about the scalability of the solution?
The great advantage of VMware is its scalability and hardware independence; The solution is compatible with a wide range of server brands, including Dell, Lenovo, HP, and Cisco.
How are customer service and support?
My job was to offer consultancy, demonstrations, and conceptual approval to the VMware official team and their partners.
How would you rate customer service and support?
Positive
How was the initial setup?
Of all the cybersecurity vendors we have, the installation of VMware products is the most straightforward. The time needed to deploy depends on the purpose of the use case. Complex tasks between two data centers could take up to four days, whereas micro-segmentation would usually take only two days.
What other advice do I have?
I give the solution an eight out of ten. The solution is missing the red teams and R&D necessary to continuously receive updates from the cloud. Additionally, two other features are absent from VMware NSX which are bandwidth limitation and URL filtering.
We have two people using the solution. I'm the only architect, and the other person is mainly responsible for checking logs to determine if any resources are needed and then assigning those resources to the appropriate virtual machines.
For someone who wants to secure their data center and three-tier application architecture (database, web application, etc.), they should use micro-segmentation with VMware NSX. This would enable them to set policies on a per-virtual machine basis. For example, if each VM has two virtual NICs assigned to it, each virtual NIC would have its own firewall, policy, and IP. This way, even when two virtual machines need to communicate with each other, their traffic will pass through two separate firewalls within the server. In addition to micro-segmentation, NSX also provides switching and routing services. The use of a data center firewall can be cost-effective for enterprise customers, SMBs, and medium-sized customers. By utilizing the routing, switching, and firewall capabilities provided by the data center firewall, the load on data center switches and routing can be reduced, making it a more cost-efficient option. The throughput required by the data center firewall, be it a Fortinet or Palo Alto Checkpoint, is directly proportional to the cost. With increased throughput, the cost of the firewall will also increase. VMware NSX offloads the workload from the data center firewall, taking on the task itself. This is possible without impacting performance because it is a software firewall, so it absorbs all the load from the data center firewall, providing the same security measures as the legacy firewall would.

An advancement in technology when compared to other solutions, but room for improvement in the non-enterprise version
Pros and Cons
- "Technically, VMware NSX is more advanced technology-wise when compared to others. We have been studying it and so far, so good. We know that the NSX product is superior when it comes to software virtualized networks. </p> <p>If you are looking to work with new and future technologies, then NSX is one of the best options. It costs less for power consumption since it will be a virtual network and not a pure physical network that consumes more energy."
- "When you're talking about virtual networks, I think NSX is one of the greatest products and will soon be the leader in the market."
- "The price could be better. The non-enterprise version of the product should also be improved. I would like VMware to expand beyond the network and provide some VLAN technologies and more. I think we have one, but it's more on the distribution side because it's more on the upper side of the network. I'm looking forward to that."
- "I want to see the solution expand to more than just the network, for example, perhaps it could provide some VLAN technologies."
- "The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
What is most valuable?
NSX is a virtual network, and now is the right time for it. Technology-wise, it's actually an advancement in comparison with other solutions. We've been studying it, and so far, so good. NSX is the superior product when it comes to software for virtualized networks.
What needs improvement?
The non-enterprise version of the solution should be improved.
I want to see the solution expand to more than just the network, for example, perhaps it could provide some VLAN technologies.
For how long have I used the solution?
I have been distributing this solution for over six years.
What do I think about the stability of the solution?
I believe the product is very stable.
What do I think about the scalability of the solution?
The product is very scalable. I don't think NSX would have any problems with growth if a company wanted to expand their network and business. One person is enough to manage this solution.
How are customer service and support?
Here in the Philippines, we need more technical support. I don't think they have good support here. There aren't any experts on NSX, only the distributor and reseller, so we have to really invest in training for us to able to understand the product.
How was the initial setup?
Our team is already trained, so the setup is straightforward.
What's my experience with pricing, setup cost, and licensing?
The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price.
What other advice do I have?
I think they need to market the solution more so that it can be accessible to more customers, because few are very familiar with it. It's hard to market it because we are provided with less marketing information about it, but in order to grow the product, it has to be properly marketed.
If you are looking for new technology of the future, NSX is one of them, and it will cost you less in power consumption since it's a virtual network as opposed to a pure physical network, which consumes more energy. That's a main advantage, that the operating expense will lessen while at the same time, the technology is great and is a secure network. When you're talking about virtual networks, I think NSX is one of the greatest products and will soon be the leader in the market.
I would rate this solution as a seven out of ten.

Reliable, with high availability and good connectivity
Pros and Cons
- "The solution is very stable and reliable."
- "The solution is very stable and reliable."
- "There were some issues with finance and other accounting."
- "There were some issues in finance and other accounting."
What is most valuable?
The stability or the high availability in connecting two or more servers has been pretty good. This is to maintain the operations in the possible highest stability. That was a very important part of this project since you have to move all virtual machines to the new infrastructure. It took a very, very long time to understand how the old architecture was arranged and how to migrate to our new architecture.
What needs improvement?
There were some issues in finance and other accounting. The applications there are very old. To move these applications, we had to use some controls or web services for programming in a new program, for example, in Python or visual C#. You have to move these applications to new programming software. It was very, very complex to move them. However, we ended up doing it very well.
ESX servers are a part that they don't implement. The client that this part of the VMware is important. You can implement more virtual machines using ESX server infrastructure. However, they couldn't complete this part since, for some arrangements in the contract, they don't put it in the contract. They need to buy new licenses to complete the project.
For how long have I used the solution?
I’ve been using the solution for six to eight months.
What do I think about the stability of the solution?
The solution is very stable and reliable. There are no bugs or glitches, and it doesn’t crash or freeze. The performance is good.
What do I think about the scalability of the solution?
We have maybe 2,000 users using the solution. We use them to move to new infrastructure.
How are customer service and support?
I have experience using help desk support to understand all the users' needs. We were in the area of quality control, so all the requirements that the users or the managers were indicating to me, we had to transfer to the area of programming and they would say, “okay, I'll let you know if I can do it or not.” I was the go-between. It worked very well. Support was offering quality service.
What about the implementation team?
I am able to help clients set up the solution. I’m an integrator.
What's my experience with pricing, setup cost, and licensing?
The original cost started at $1,500. The solution is paid monthly. All the institutions have to pay monthly for the services in the cloud. They have to pay $30,000 every month for this service every three years.
What other advice do I have?
I am not a reseller. I am an integration company. More prominent companies contract us and we work for them.
I’d rate the solution nine out of ten.
VMware is a very, very good product. It's used a lot here in Ecuador in a lot of enterprises and institutions.
