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.

Has enabled consistent enforcement of zero-trust policies at the virtual layer
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. It protects them and helps them communicate with each other without needing a complex external or internal firewall in this use case. Working with the zero-trust security model means never trust but always verify. Every VM, application, and service in your environment must explicitly prove it's allowed to communicate with others. An application would be able to talk to a VM and vice versa. This zero-trust means explicitly proving that they are allowed to talk to each other, with no implicit trust just because they are on the same VLAN, subnet, cluster, or environment. Nutanix Flow brings the zero-trust model natively to the virtual layer inside the Nutanix software itself, the AHV. The AHV software enforces strict communication rules between workloads. Integration between Nutanix Flow and other products natively benefits the infrastructure itself as this is a networking segmentation software coming from Nutanix itself. This provides ultimate compatibility. There is no need for extra firewall VMs such as Palo Alto or third-party switches. Security becomes established at the hypervisor level, which creates a new conglomeration of security segmentation. The network performance analysis that Nutanix Flow Network Security provides is very beneficial and effective.

Quotes from Members

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

Pros

"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."
"The Explorer allows you to know the traffic between source and destination."
"I observe extensive return on investment with Illumio."
"The tool helps with my company's security posture."
"Customer support is excellent."
"It has helped us to understand internal network visibility and firewall policy implementation. We use the product to simplify firewall policy implementation."
"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."
"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."
"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."
"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."
"When comparing the costs of Nutanix Flow versus managing multiple VLANs and many other firewalls, it is far less expensive."
"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."
"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."
"Flow Network Security's most valuable features are user-friendliness, the console, and policy creation."
 

Cons

"The customer service is lagging a bit. It could be better."
"Illumio Adaptive Security Platform could improve by supporting more operating systems, for example, Cisco and Apache appliances."
"I have not had the chance to experiment deeply with it."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades."
"Illumio does not have much in terms of application dependency mapping features."
"Illumio can be improved if we have more interactive sessions with the tech team."
"The product’s agents don't work very well in OT environments."
"Illumio requires me to create policies for each type of traffic, and for new users, the policy design can be a bit complex."
"The documentation offered by the product is an area with certain shortcomings where improvements are required."
"Nutanix Flow's networking features could use some improvement."
"Nutanix Flow Network Security needs to improve threat hunting, compliance, and policy optimization - these things that security officers would use."
"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."
"The solution’s pricing could be improved."
"I would rate Flow Network Security's stability seven out of ten - it could be improved."
"The most difficult part is the configuration of the initial blueprints."

"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."
"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."
"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."
