User friendly, cloud scalability, with surpassed return on investment goals
I found that it has a good GUI and user-friendly administration They need to have some automation models embedded in them. If you integrate that, that would be a complete package. I have been using Nagios Network Analyzer for the past five years. Nagios Network Analyzer is very stable. They…

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.

"I have found that it has a good GUI and user-friendly administration."
"Network tracking is the most valuable feature of Network Analyzer."
"The network monitoring feature, especially, stands out to me."
"The solution offers very good system monitoring. It's easy to manage your network, as well as your hardware and software. It's really useful."
"The most valuable feature of VMware NSX is the ease of use and its user friendly. For example, it is simple to change the subnet masks."
"Firewall security is one of VMware NSX's vital features"
"It has reduced the number of people on the network team along with the system engineer involved in the security process. So, it is valuable."
"The most valuable features are the micro-segmentation and integrated security options."
"You can easily integrate this with other VMware products. It is a robust solution."
"The product has valuable features for security and network extension."
"NSX is good in managing security or controlling the security and the access control for each single VM."
"From a security standpoint, the customer was able to better secure critical workloads while routing L2/L3 worked normally, giving them more confidence that they would be ready for any potential security incident mitigation or outage (DR)."
 

Cons

"I think the reports can be improved. They're adopted."
"There is room for improvement on the setup side."
"There are some loopholes you need to be aware of from a security perspective."
"Nagios Network Analyzer should integrate an application monitoring solution to monitor application bandwidth usage."
"It has an old-fashioned interface."
"The bandwidth for its front-end version needs enhancement."
"The graphics and reports can be a little bit better."
"They need to have some automation models embedded in them."
"The training costs a minimum of $3,000, which is expensive and should be reduced."
"It might be nice to have more AI in the future."
"Migrating from V to T is very tricky, complicated, and there are a lot of parameters to account for."
"We would like better integration with the standards on the market. For example, with OSPF, their integration in NSX is very low. It's not a full OSPF integration. It is too thin from a protocol perspective."
"In the next release, they should enhance the visual interface. With NSX-T, it's difficult to communicate between the public cloud and the container."
"It isn't easy to deploy."
"The setup of the solution could be simplified."
"Going through and getting more features sets from the routing protocols is definitely necessary for the future."
 

Pricing and Cost Advice

"The solution is cost-efficient."
"They charge around ten thousand per month for one thousand nodes. That is their overall cost, but it differs on which company you are applying to, whether you are a service provider or an enterprise."
"I rate Nagios Network Analyzer's pricing a six out of ten."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"Our customers have definitely complained about its cost. It's expensive. I'd rate it a nine out of ten in terms of pricing where ten represents a high price. There are other products out there that are equally expensive."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
"The pricing model for VMware NSX is good."
"The solution is very expensive."
"The subscription is on a yearly basis."
"VMware NSX is a cheaper product compared to its competitor, Cisco."
"The solution is reasonable at the local level."
