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

"I would recommend Illumio to all sizes of companies."
"We have been using the Illumio Adaptive Security Platform for a while now and we have seen a return on investment."
"Illumio serves as a single endpoint technology where I can implement various features, including a zero-trust network, north-to-south and east-to-west configurations, and micro-segmentation, all coming from one platform, which ultimately saves us time and money."
"The Explorer allows you to know the traffic between source and destination."
"The product provides visibility into how the applications communicate and how the network protocols are being used."
"Everything is valuable in Illumio."
"The solution is easy to use."
"Illumio definitely demonstrates its value in money-saving capabilities, enhancing our lateral environment inside the organization and providing effectiveness overall once integrated."
"The micro-segmentation feature helps to manage network security effectively because it helps the virtual machines that are already on the cluster and the applications inside the cluster itself, protects them and helps them communicate with each other without needing a complex external or internal firewall in this use case."
"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."
"It allows for policies that enable complete visibility and traffic control."
"Flow Network Security's most valuable features are user-friendliness, the console, and policy creation."
"Nutanix Flow is straightforward to install. You only need to select a checkmark that you want to enable Nutanix Flow."
"They also introduced that they develop API first and the rest follows."
"It is a very stable solution. Stability-wise, I rate the solution a ten out of ten."
 

Cons

"Illumio can be improved if we have more interactive sessions with the tech team."
"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."
"Sometimes, the PCE experiences slowness, especially when deploying around 300,000 endpoint devices."
"I would like to see better data security in the product."
"I would appreciate if Illumio Segmentation's interface were better."
"The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules."
"Illumio Segmentation can be improved by further implementing some plugins for tasks such as restart operations for which we don't have the right approvals to get into the server and do that work."
"One area for improvement regarding Illumio might be making the policy management even more intuitive."
"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."
"I would like to see better micro-segmentation capabilities in Nutanix Flow Network Security."
"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."
"The solution’s pricing could be improved."
"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."
"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 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."
"There are different licensing models."
"This model is very accessible to implement."
"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."
"The product is available for free use."
