Micro segmentation has strengthened zero trust security and isolates production from test environments
The advantages of VMware NSX include its micro-segmentation for internal security at the firewall and VM levels, which is very powerful and helps us comply with complete Zero Trust security models. We are able to achieve this and configure network level virtualization with no dependency on VLANs. Micro-segmentation helps improve our security significantly. We are not totally dependent upon our physical upfront firewall, and it makes sense to configure everything using VMware NSX, leading to multiple improvements in our organization. We moved from traditional networking such as VLANs from the firewall and switches to VMware NSX segmentation. We achieve one firewall per VLAN and can stop lateral movement such as ransomware control. The Zero Trust model is the main functionality and architecture it offers, allowing application isolation, such as having a separate production and test environment. Consistent networking and security policies across different environments have a major and very positive impact on our business operations, allowing us to achieve the security posture we want with compliance and regulations.

Quotes from Members

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

Pros

"If people or users are complaining that the network is slow, Flowmon can easily detect the cause of the network problem."
"Flowmon is more easy to understand and helps find network issues more quickly."
"It is an open platform, so in terms of integration, we are quite happy. We can integrate it with other SNMP solutions. We can also integrate it with security solutions, such as a SIEM solution."
"The artificial intelligence and automatic detection system in Flowmon Solution are perfect for every, type of customer, such as government and commerce."
"The solution is both stable and scalable and we are happy with the product."
"The solution is stable."
"It's what we use the CIS Benchmarks for. It's for employing hardening rules and keeping them up to date when things happen on our systems. So it's really configurations and stuff that harden and report back."
"Our clients are very satisfied that we can limit ourselves to NSX without the need to purchasing additional network systems and physical devices."
"VMware NSX is a very good solution. It's also a scalable solution."
"The Distributed firewall is simple to add to the network and rules are easy to implement."
"The best part is the blueprint creation where I can create their things and then move on to the target environment."
"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."
"The most valuable features are stability and low cost."
"VMware NSX offers some of the best features for security, such as micro-segmentation."
 

Cons

"The price of the license could be lower."
"If there was better visualization in Flowmon Solution it would be good."
"I do not know the detailed pricing."
"It would be helpful to have more details about the monitoring of the infrastructure. It should have support for SNMP. This is something that is currently not there in the product."
"A faster resolution time would be beneficial."
"Speed of the NSX Controllers while deploying sometimes gets a bit slower which can be improved, overall its a great product"
"A room for improvement in VMware NSX is that it has some security vulnerabilities, which means my company has to apply the patches every once in a while."
"The vendor should integrate a basic load balancer in future versions"
"The first time setting it up was difficult."
"It needs to be cheaper."
"However, they should provide better documentation."
"The initial establishment can be complex."
 

Pricing and Cost Advice

"The licensing fee accrues only once, but that of support is annual."
"The price of the solution could be better."
"It works with a permanent license, and then you can pay for the support. For the gold support, you need to pay yearly."
"It is an expensive product, but cheaper than some competing solutions."
"The pricing is higher than other options from Palo Alto, Fortinet, and Cisco because it is sold in a bundle."
"The cost of the solution is a bit high."
"The price of VMware NSX is very good compared to other solutions."
"The solution is reasonable at the local level."
"The subscription is on a yearly basis."
"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."
