Featured Reviews

Irfan Sharfi - PeerSpot reviewer

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 tool helps with my company's security posture."
"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 client is getting more security and is more confident in their network because they now have the micro-segmentation feature in their environment."
"The features that I have found most useful is the ability to centralize all the rules and then distribute them across various locations. However, I've encountered challenges related to tagging policies, which can be complex to devise. It's a matter that requires careful consideration and stakeholder involvement before implementing such policies."
"The product provides visibility into how the applications communicate and how the network protocols are being used."
"The Explorer allows you to know the traffic between source and destination."
"The flexibility of the solution is its most valuable feature."
"The solution is easy to use."
"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."
"Nutanix Flow is straightforward to install. You only need to select a checkmark that you want to enable Nutanix Flow."
"Nutanix Flow has a lot of data protection features. It's also valuable for operations and management. It's a big solution that works well with different solutions and is suitable for most business cases."
"They also introduced that they develop API first and the rest follows."
"It allows for policies that enable complete visibility and traffic control."
"We appreciate the fact that this solution allows us to segregate two virtual machines that are in the same cluster."
"Nutanix Flow Network Security is a simple solution that is usable, easy to understand, and easy to deploy."
"When comparing the costs of Nutanix Flow versus managing multiple VLANs and many other firewalls, it is far less expensive."
 

Cons

"I would appreciate if Illumio Segmentation's interface were better."
"Illumio requires me to create policies for each type of traffic, and for new users, the policy design can be a bit complex."
"Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices."
"Illumio supports both on-prem and cloud environments, but I think the GUI interface could be more user-friendly."
"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"So far, we haven't been too satisfied with the assistance they've provided."
"I would like to see better data security in the product."
"It requires a low-level re-architecting of the product."
"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."
"The most difficult part is the configuration of the initial blueprints."
"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."
"For customers who are running Nutanix Flow and AHV, the largest area for improvement is in the disaster recovery environments."
"Nutanix Flow Network Security needs to improve threat hunting, compliance, and policy optimization - these things that security officers would use."
"While the graphical interface of Nutanix Flow Network Security could have been improved, and some of the reporting features needed extra work, the product's features were similar to VMware's NSX. The difference lay more in the presentation and user interface."
"We would like the reporting functionality of this solution to be improved."
 

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 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."
"This model is very accessible to implement."
"Flow Network Security is available on a three-year license, with annual renewals of the maintenance fee."
"There are different licensing models."
"The product is available for free use."
"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."
"In comparison to other options available in the market, I would rate their pricing as very competitive, probably a two or three out of ten for cost."
