An open-source solution that gave us insight into our clients' network traffic flow
We use the solution for packet capture sampling. We offer it as part of our managed service. It's so we can identify east-west traffic on a customer's network Corelight is low-cost and made on open-source, and the code is Zeek. It's an easy way for us to get visibility in a client's environment.…
DanielBass - PeerSpot reviewer
Improves network security with micro-segmentation but setup is complex
I value the ability to dynamically configure our network on the fly using VMware NSX. This flexibility is a huge advantage because it allows us to avoid static configurations that come with traditional hardware setups. Additionally, the micro-segmentation feature is beneficial for adhering to strict security regulations from our security department.

"There are always issues integrating with Cisco."
"The network-extending capabilities for the physical environment need improvement."

Pricing and Cost Advice

"It's a yearly fee and depends on what you are looking for."
"The price of VMware NSX is very good compared to other solutions."
"The licensing is renewed every three years. The cost for implementation and renovation are a huge portion of that price."
"You can scale NSX if you have the resources, but it's usually expensive and complex to scale up."
"Pricing and licensing could be improved as we are a government entity. Lower pricing could always help."
"The implementation of VMware NSX can be cost-intensive, especially if an organization is looking for a comprehensive solution. The costs can vary based on factors like the level of conversation and discounts obtained during negotiations. Some government organizations, for instance, may find the prices relatively high, leading to concerns about budget hikes, especially when deploying the solution across the entire organization. Regarding maintenance and support, they are typically included in the standard licensing costs for enterprise-level businesses. While these costs can be significant, many companies opt for standard licensing to ensure they have access to necessary support and maintenance services."
"There is a license required for this solution and there is also a support license available. The price of the solution could be better."
"The solution is reasonable at the local level."
"The cost of the solution is a bit high."
