Offers great integration capabilities and helps design a disaster recovery plan
My company is still determining how the product has improved network visibility. My organization is still actively developing the product. There are many things my company is doing in the background to make sure that our VMs come up. My company deals with Nutanix Cross Hypervisor Disaster Recovery, so we are moving from an ESXi or VMware to Nutanix AHV, meaning that my company is crossing over from hypervisor technologies and leveraging Nutanix to maintain the networks at our DR facility. The most valuable feature of the product in enhancing the security posture stems from the micro-segmentation provided by the product, but I think that it is a functionality in its early stages. The product's micro-segmentation features are being developed to be made robust against technologies such as NSX from VMware and other hypervisor-dependent technologies such as Guardicore. I can't say that the product has given my company any additional features yet, but we hope that the tool will provide us with additional functionalities in the future. The product's micro-segmentation features seem to be on par with the other technologies in the market when it comes to its ability to isolate workloads. I haven't noticed any improvements in my company due to the automation capabilities of the product, especially since everything is done manually in our organization because we know the application very well, and we also know how we want to protect it. I am sure the product has automatic features, but we haven't used them in our company. There has been a positive impact due to the integration capabilities of the product with the other solutions in our company's IT infrastructure. I recommend the product to those who plan to use it, especially those who use Nutanix AHV as a hypervisor. It would be a good choice to work with the account rep in your company so that you can get a system engineer to help you walk through the majority of the deployment and setup phases since the documentation has certain shortcomings. I rate the overall tool a ten out of ten.

Enhanced security and streamlined management drive efficient connectivity
Open source is a standard solution where you take a gray box or white box and put the software from your end. You can do programming with Ansible and make the network work in the software-defined mode, providing automation and management capabilities. I am currently working with VMware. It integrates easily with everything and can work with any system. When discussing micro-segmentation, it enhances security, providing more secure data in your data center while allowing for extra layers of security outside your data center. If you have an ACI, there is communication between locations, keeping your data secure in your data center and throughout the path it takes, such as to SD-WAN or the cloud. I work with cloud solutions including AWS, Azure, GCP, and private cloud. My overall rating for VMware NSX is 8.5 out of 10.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"Nutanix Flow Network Security is a simple solution that is usable, easy to understand, and easy to deploy."
"It allows for policies that enable complete visibility and traffic control."
"The network view was excellent as it allowed us to expand the server view and visualize all connections it made within the environment. This was particularly useful in identifying the path of our data and not just its location within the data center."
"Nutanix Flow is straightforward to install. You only need to select a checkmark that you want to enable Nutanix Flow."
"Nutanix Flow has a lot of data protection features. It's also valuable for operations and management. It's a big solution that works well with different solutions and is suitable for most business cases."
"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."
"Flow Network Security's most valuable features are user-friendliness, the console, and policy creation."
"They also introduced that they develop API first and the rest follows."
More Nutanix Flow Network Security pros
"Over the last two years, they've enhanced a lot, especially in regard to integration with OpenStack."
"They have a lot of support and specialists who can meet with the customer."
"It provides a single pane of glass. You can do the switching, routing, load balancing, IPS, IDS, etc. Everything is under one umbrella. So, there is no vendor dependency over there."
"One significant advantage of VMware NSX is the ability to provide advanced security at the micro-level, focusing on securing applications and workloads rather than just the network structure or virtualization-based network security."
"I have found the system to be very intuitive, functional, and they have great technology."
"I have found the solution to be stable."
"It is easy to implement it."
"When you have a solid secure solution between your on-prem and cloud solution, then you're in a safe place."
More VMware NSX pros
 

Cons

"The documentation offered by the product is an area with certain shortcomings where improvements are required."
"The solution’s pricing could be improved."
"For customers who are running Nutanix Flow and AHV, the largest area for improvement is in the disaster recovery environments. To automate the populate of rules from one side to the other side in case of disaster you report everything on the disaster recovery site, and you have all the rules automatically applied. This was something that was being built when I left Nutanix. It might already be available. Additionally, the usability of the rules editor could improve."
"Nutanix Flow's networking features could use some improvement. Also, I don't know if it's currently supporting load balancing or not."
"While the graphical interface of Nutanix Flow Network Security could have been improved, and some of the reporting features needed extra work, the product's features were similar to VMware's NSX. The difference lay more in the presentation and user interface."
"The most difficult part is the configuration of the initial blueprints."
"Last time I used it, it was not handy to see or to analyze traffic logs."
"We would like the reporting functionality of this solution to be improved."
More Nutanix Flow Network Security cons
"Nowadays, NSX supports the KVM and ESXi hypervisors only. It should also support Hyper-V and Citrix hypervisors."
"It might be nice to have more AI in the future."
"VMware NSX provides a lot of automation capabilities, but there is still room for improvement."
"I would rate this product an eight because it's a good product but it needs more work. They should fix some of the bugs."
"The initial setup for VMware NSX is a bit complex; it's not as simple as it could be."
"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."
"There are sometimes mismatch in the control, the details and what you actually see on the transport note."
"VMware NSX only supports some platforms like KVM."
More VMware NSX cons
 

Pricing and Cost Advice

"There is an annual subscription to use this solution. There is a 60-day trial to use the solution, it gives you time to decide if you want to continue using the solution."
"In comparison to other options available in the market, I would rate their pricing as very competitive, probably a two or three out of ten for cost."
"The product is available for free use."
"Flow Network Security is available on a three-year license, with annual renewals of the maintenance fee."
"There are different licensing models."
"This model is very accessible to implement."
"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing a seven out of ten."
"The cost of the solution is a bit high."
"This solution requires a licence."
"There is a license required for this solution, we pay annually."
"We are using the free version of the solution."
"VMware has always been geared towards enterprise and their pricing options are a bit high. Their price is higher than other options in the market."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"VMware has a subscription and perpetual license. In the New Year, they're changing many things about the licensing model. Previously, NSX was licensed according to the number of sockets inside the appliance, so we bought VMware licenses based on that. However, that may have changed this year. We are still contacting the vendors to understand the new licensing strategy."
"The subscription is on a yearly basis."
