Alark Singh - PeerSpot reviewer
Visual traffic interface aids in network micro-segmentation while a streamlined update option enhances process efficiency
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. We can write rules that can be embedded into the IP table, making it easy to handle. Illumio enables us to see network flows, traffic sources, and destinations. The policy generation and enforcement capabilities are valuable, allowing for selective enforcement. Illumio helps in audit purposes by saving data and showing blocked traffic, ensuring no outside traffic is allowed.

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.

"I would like to see better data security in the product."
"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. This would be more helpful to streamline processes."
"It requires a low-level re-architecting of the product."
"The interaction we've had with the support team hasn't been ideal. Technical support should be improved."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"The product’s agents don't work very well in OT environments."
"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."
"The solution’s pricing could be improved."
"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."
"I would rate Flow Network Security's stability seven out of ten - it could be improved."
"Nutanix Flow Network Security needs to improve threat hunting, compliance, and policy optimization - these things that security officers would use."
"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."
