Cyber Security Architect at a tech vendor with 10,001+ employees
Have created granular security policies based on roles and application behavior
The best feature that Illumio offers is that we can easily understand how to label the applications, how to install Illumio agent on the client machines, how to install the agent on the servers, and how to do the ring-fencing. The log analysis is very simple, and we can map the traffic very easily, such as the traffic view and map view. We have many views to do that, and then we have a topology environment where we can expand the topology and understand how we want to prepare our policy based on the requirement. These are some of the very good use cases that Illumio provides, which none of the other vendors can offer in such an easy and usable way. The most important feature is the traffic review analysis, where we use the draft view and the reported view that helps us understand how the application interacts with other applications in the environment, and based on that, we are able to define the policies. It has increased the business for the organization. We are creating business by supporting the client. The client is getting more security and is more confident in their network because they now have the micro-segmentation feature in their environment. This is new technology and that's how it helps the organization as a whole. The clients we support are benefited, and at the same time, we are making money out of it. This is definitely a good approach. After implementing Illumio, there has been significant progress. Most of the app owners now understand what applications are communicating, how these applications interact with others, and we are more aware of which application is talking to what other servers and applications, and their roles. For instance, whether an application is talking to the DB server or an app server. We have a more granular understanding of the traffic view. Additionally, after implementing Illumio, there is greater segmentation, and fewer incidents are occurring. There have been times when an attack was halted from expanding laterally.

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 strongest aspect of Illumio is the visual traffic interface, which allows us to see all traffic that communicates with our servers and allied companies."
"The dependency map is most valuable feature."
"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."
"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."
"I would recommend Illumio to all sizes of companies."
"The flexibility of the solution is its most valuable feature."
"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."
"They also introduced that they develop API first and the rest follows."
"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."
"Nutanix Flow Network Security is a simple solution that is usable, easy to understand, and easy to deploy."
"It allows for policies that enable complete visibility and traffic control."
"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."
"We appreciate the fact that this solution allows us to segregate two virtual machines that are in the same cluster."
"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."
"I would like to see better data security in the product."
"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."
"Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances."
"It requires a low-level re-architecting of the product."
"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."
"There should be an option to upgrade from the console to the latest version instead of performing manual upgrades."
"The product’s agents don't work very well in OT environments."
"We would like the reporting functionality of this solution to be improved."
"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."
"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."
"Last time I used it, it was not handy to see or to analyze traffic logs."
"I would rate Flow Network Security's stability seven out of ten - it could be improved."
"The documentation offered by the product is an area with certain shortcomings where improvements are required."
"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
