Featured Reviews

Irfan Sharfi - PeerSpot reviewer
Security Professional at a tech vendor with 10,001+ employees
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

"I observe extensive return on investment with Illumio."
"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."
"Illumio Segmentation has had a positive impact on my organization, as it has created a very impressive impact because it is a worldwide operation."
"Overall, Illumio is a powerful tool for micro-segmentation and zero trust security that provides strong visibility, flexible policy management, and effective threat containment, enhancing an organization's internal security posture."
"One big outcome we saw after implementing Illumio was a notable drop in lateral movement incidents."
"Illumio does more than general security product, it provides East-West traffic flow visibility and auditorial log which benefits on daily operation and periodical auditing."
"The flexibility of the solution is its most valuable feature."
"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."
"Nutanix Flow is straightforward to install. You only need to select a checkmark that you want to enable Nutanix Flow."
"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."
"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 Network Security is a simple solution that is usable, easy to understand, and easy to deploy."
"We appreciate the fact that this solution allows us to segregate two virtual machines that are in the same cluster."
"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."
"When comparing the costs of Nutanix Flow versus managing multiple VLANs and many other firewalls, it is far less expensive."
"What I like about Nutanix Flow Network Security is that it features cloud-like segmentation, which is available in a hybrid environment for us."
 

Cons

"It requires a low-level re-architecting of the product."
"I would appreciate if Illumio Segmentation's interface were better."
"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."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades. This would be more helpful to streamline processes."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"Technical support could be better. When we get a reply from support engineers, it is not kind or empathetic."
"Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices."
"One area for improvement regarding Illumio might be making the policy management even more intuitive."
"The documentation offered by the product is an area with certain shortcomings where improvements are required."
"I would like to see better micro-segmentation capabilities in Nutanix Flow Network Security."
"I would rate Flow Network Security's stability seven out of ten - it could be improved."
"Nutanix Flow's networking features could use some improvement. Also, I don't know if it's currently supporting load balancing or not."
"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."
"Last time I used it, it was not handy to see or to analyze traffic logs."
"The most difficult part is the configuration of the initial blueprints."
"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."
"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."
"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."
"Flow Network Security is available on a three-year license, with annual renewals of the maintenance fee."
"The product is available for free use."
"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."
"There are different licensing models."
"This model is very accessible to implement."
