Micro-segmentation has improved threat visibility and supports ongoing zero-trust monitoring
Deployment of Illumio Insights was not difficult, but the difficulty depends on how micro your design is. For Docker containers, it is not quite suitable for that kind of application traffic. For container architectures, it is not quite designed that way. For normal VMs it might be acceptable, but for container architectures, I cannot be as micro-segmented as I want to be. Illumio Insights is not very well designed for containers, which is one of the drawbacks and weak sides of the product. I use Illumio Insights' real-time analytics for micro-segmentation, and beyond zero-trust monitoring, I also want to do analysis. However, the product coverage is not very broad, so I have to do my own filtering and analysis, and integration with other tools is necessary. The reporting and analysis are not ready out of the product itself. Reporting is another area for improvement in this product and is not very sufficient, so I have to further integrate or do it on my own. Illumio Insights is stable and a mature product. The functionality, such as reporting and analysis, may extend in the roadmap, but it has not in the past. The current functionality is adequate and quite mature, which is how I chose it based on maturity and market share. However, it is not very modern for Kubernetes and containers. If this functionality can extend, that would be a valuable roadmap addition. Streamline integration with Illumio Insights does not help me much since it does not require too much integration with my other operations.

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

"This solution has contributed to quick detection of risky traffic and offers one-click containment."
"Illumio Insights impressed me with its ease of use, clarity, and potential to significantly improve breach containment strategies."
"Illumio Insights is stable and a mature product."
"One of the most valuable features is the ability to map traffic and patterns over multiple hyperscalers, not just AWS."
"The most valuable feature of VMware NSX is the high bandwidth."
"One significant advantage of VMware NSX is the ability to provide advanced security at the micro-level, focusing on securing applications and workloads rather than just the network structure or virtualization-based network security."
"It's pretty stable. Just deploy it and just forget about it."
"We enjoy the micro-segmentation and the ability to extend the network on Layer Two."
"One of the big improvements between the NSX-V and NSX-T is that in NSX-T you are no longer dependent on V-Center anymore."
"NSX is extremely invaluable from the standpoint of security."
"Overall, I would say the solution has been quite stable."
"Apart from the normal functionality, a few things are quite useful, including multi-cloud networking, container networking, and load balancing, which are quite useful when we are designing a solution, and it's a pretty mature platform right now."
 

Cons

"There is room for improvement with more AI-based detection to report traffic abnormalities and potential issues."
"Illumio Insights is not very well designed for containers, which is one of the drawbacks and weak sides of the product."
"In some of the views, an IP address appears to be a link, but it doesn't open any new windows or display any new information."
"The VMware technical support could be better. They're not always reachable and expertise is not widespread."
"Nowadays, NSX supports the KVM and ESXi hypervisors only. It should also support Hyper-V and Citrix hypervisors."
"Our technical team is always looking for the solutions that they work with to offer more convenient integrations."
"If you start with a new or greenfield environment, it is okay to implement. However, if there are other solutions already in place, it can be difficult to implement."
"The integration with other brands is not the best and could be better."
"The reporting functionality could be better, and there could be an easier way of forwarding events. There's room for improvement in the product."
"In the next release, they should enhance the visual interface."
"Migrating from V to T is very tricky, complicated, and there are a lot of parameters to account for."
 

Pricing and Cost Advice

Information not available
"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."
"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."
"I was not involved in the purchase of the solution but I hear it is on the expensive side."
"The cost of the solution is a bit high."
"The price of VMware NSX is optimal. Additionally, the price of the solution can be negotiated with the vendor. Many areas of the solution can impact the cost, such as features, time for onboarding, and support needed."
"The price of this product is too high."
"We have saved man-hours and decreased our security exposure."
