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

"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 Network Security is a simple solution that is usable, easy to understand, and easy to deploy."

"Nutanix Flow is straightforward to install. You only need to select a checkmark that you want to enable Nutanix Flow."

"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."

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

"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."

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

More Nutanix Flow Network Security pros

"NSX can reduce costs and has good service. It is easy for you and your users to use."

"NSX has excellent security features like virtual firewalls. I also like the micro-segmentation features, which are useful for the virtual machines inside the servers."

"It does have capabilities of micro-segmenting a network, being able to create smaller segments of various types of applications separated by various tiers."

"It's very important for them to have small footprints and have as much services in their servers, as possible."

"I rate the scalability as ten out of ten."

"The interface is intuitive enough."

"The initial setup was straightforward. It follows a certain structure and you won't miss a step. It's all on the same level, step by step."

"VMware NSX has the ability to create networks in software."

More VMware NSX pros

Cons

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

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

"The most difficult part is the configuration of the initial blueprints."

"The solution’s pricing could be improved."

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

"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."

"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."

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

More Nutanix Flow Network Security cons

"I would like to have automating reporting built into common service management platforms, such as JIRA, Serviceaide, and ServiceNow."

"They could do more with cloud management."

"The solution is quite complex. You need to keep your thinking cap on and know what you are doing: Go to the training and listen to the solution architects when they come in because they have a lot of knowledge."

"It lacks full knowledge of physical side of the network topology."

"Some configuration maximums are limiting to the user, especially when it comes to the deployment of very, very large environments."

"VMware NSX can improve the migration tools from the older environments to the new environment. For example, the NSX-V has become a legacy solution, it's out of support, but customers are able to keep using it. For migration purposes, it's better for them to provide a proper tool. It will be easy to migrate from an old environment to a new one."

"The initial establishment can be complex."

"The licensing model is expensive and could be more flexible, especially after Broadcom bought VMware."

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."

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

"This model is very accessible to implement."

"There are different licensing models."

"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."

"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."

"We haven't had to hire a dedicated network engineer because NSX handles 90 percent of it. The reduced overhead in terms of managing networks has been the biggest plus."

"We have saved man-hours and decreased our security exposure."

"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."

"VMware NSX is expensive and everything is licensed. We have to pay for each individual feature."

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

"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 pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."

"This solution requires a licence."
