Micro-segmentation has transformed endpoint protection and now isolates internal threats effectively
Illumio can be improved in several areas based on our feedback. Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices. When these devices communicate within the network, loading the map or connections can cause latency, which needs improvement for a more user-friendly and faster experience. Regarding improvements to the interface, I believe we can add more features to the graphical user interface, such as proper logs. While the logs currently indicate what was blocked or allowed, clicking on a specific log should provide more information, such as which extra-scope rule is causing a denial, offering better analysis for troubleshooting.

Cloud-style segmentation has improved hybrid security but integration with on-prem tags still needs work
I would like to see better micro-segmentation capabilities in Nutanix Flow Network Security. It has to work with our Cisco on-premises tooling. We use something called tagging on-premises, so if the same tags could be used in Nutanix Flow Network Security, then that would make life easier. The Cisco part was a challenge in terms of how it integrates with third-party vendors and tools, so we have kept it for the next release.

Quotes from Members

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

Pros

"The strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies."
"The client is getting more security and is more confident in their network because they now have the micro-segmentation feature in their environment."
"I would recommend Illumio to all sizes of companies."
"The Explorer allows you to know the traffic between source and destination."
"Customer support is excellent."
"The solution is easy to use."
"The most valuable feature of Illumio Adaptive Security Platform is monitoring. When I have no requirement from the other application, I can use the web block traffic to build."
"The solution helps to maintain logs and monitor activities. It also helps us with access management. The tool helps us to secure organizational data that include files."
"What I like about Nutanix Flow Network Security is that it features cloud-like segmentation, which is available in a hybrid environment for us."
"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 is straightforward to install. You only need to select a checkmark that you want to enable Nutanix Flow."
"We appreciate the fact that this solution allows us to segregate two virtual machines that are in the same cluster."
"When comparing the costs of Nutanix Flow versus managing multiple VLANs and many other firewalls, it is far less expensive."
"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."
"It allows for policies that enable complete visibility and traffic control."
 

Cons

"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"Illumio does not have much in terms of application dependency mapping features."
"I would like to see better data security in the product."
"We need more details on areas where there is an error or a traffic blockage. I would like the tool to offer a more detailed view."
"Some of the features that can be improved is offer additional guidance on creating an effective and risk-free tagging policy would be highly beneficial."
"The customer service is lagging a bit. It could be better."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices."
"I would rate Flow Network Security's stability seven out of ten - it could be improved."
"We would like the reporting functionality of this solution to be improved."
"The solution’s pricing could be improved."
"Nutanix Flow Network Security needs to improve threat hunting, compliance, and policy optimization - these things that security officers would use."
"The most difficult part is the configuration of the initial blueprints."
"Nutanix Flow's networking features could use some improvement. Also, I don't know if it's currently supporting load balancing or not."
"I would like to see better micro-segmentation capabilities in Nutanix Flow Network Security."
"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."
 

Pricing and Cost Advice

"The product's pricing is around 10,000-15,000 USD. The pricing is on a yearly basis."
"There is a subscription needed to use Illumio Adaptive Security Platform and we pay every three years. Overall the solution is expensive."

"There are different licensing models."

"This model is very accessible to implement."
"The product is available for free use."
"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."
"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."
