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

"We appreciate the fact that this solution allows us to segregate two virtual machines that are in the same cluster."

"Flow Network Security's most valuable features are user-friendliness, the console, and policy creation."

"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 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."

"They also introduced that they develop API first and the rest follows."

"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."

More Nutanix Flow Network Security pros

"The installation is straightforward, it took a couple of hours."

"NSX helps us by making IT management and operations more efficient. When VMs spin off from the DC to the DR site, all required settings on the network level are handled automatically."

"Overall, I would say the solution has been quite stable."

"I really like the management dashboard, the tailor-made assurance, the telemetry, and the ease of integration with all other solutions of VMware, such as vSphere."

"The most valuable feature of VMware NSX is the DFW (distributed firewall)"

"The most valuable feature of VMware NSX is the high bandwidth."

"The alert features are the most valuable."

"The security offered by VMware NSX is the most valuable, plus it's a feature-rich product that's straightforward to install and configure."

More VMware NSX pros

Cons

"Nutanix Flow's networking features could use some improvement. Also, I don't know if it's currently supporting load balancing or not."

"The solution’s pricing could be improved."

"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."

"I would rate Flow Network Security's stability seven out of ten - it could be improved."

"We would like the reporting functionality of this solution to 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."

"Last time I used it, it was not handy to see or to analyze traffic logs."

More Nutanix Flow Network Security cons

"The initial establishment can be complex."

"We had some complexities implementing into the other parts of a network."

"It could be more user-friendly, but it's manageable. When we add a specific node to this particular NSX and the configuration changes, it won't push through the errors where required, but it'll accept it. However, while using it, we will have issues. It can also be more stable."

"The training costs a minimum of $3,000, which is expensive and should be reduced."

"I would like them to make integration with other vendors easier."

"The support from VMware NSX could improve."

"It takes time to do the initial setup. It is a bit slow, which is surprising."

"Its licensing model could be VM based."

More VMware NSX cons

Pricing and Cost Advice

"The product is available for free use."

"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."

"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."

"Flow Network Security is available on a three-year license, with annual renewals of the maintenance fee."

"There are different licensing models."

"The price could be better. We pay for the license every three years. The last time I checked, it cost around three million pesos in the Philipines. Most of the expense will go towards implementation and renovation."

"If five is a good price and one is a high price, I would rate the price a one out of five."

"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."

"It is an expensive product, but cheaper than some competing solutions."

"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 solution is very expensive."

"We can't go without NSX, so it's invaluable from this perspective."

"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
