Micro-segmentation has improved threat visibility and supports ongoing zero-trust monitoring
Reviewed on Jun 22, 2026
Review provided by PeerSpot
What is our primary use case?
Illumio Insights plays its own role in enhancing threat visibility. Illumio Insights performs micro-segmentation according to the traffic, determining whether to trust it, allow it, or block it. Micro-segmentation is also a network access control at the network level. It does not understand or read the contents inside packets; it is not a WAF that can block SQL injection or web injection. It operates only at the TCP level and network level.
What is most valuable?
I use Illumio Insights' real-time analytics for micro-segmentation and zero-trust monitoring, which allows for analysis. However, the product coverage is not very broad, so I have to do my own filtering and analysis, and integration with other tools is necessary. The reporting and analysis features are not ready out of the product itself.
What needs improvement?
Deployment of Illumio Insights was not difficult, but the difficulty depends on how micro your design is. For Docker containers, it is not quite suitable for that kind of application traffic. For container architectures, it is not quite designed that way. For normal VMs it might be acceptable, but for container architectures, I cannot be as micro-segmented as I want to be.
Illumio Insights is not very well designed for containers, which is one of the drawbacks and weak sides of the product.
I use Illumio Insights' real-time analytics for micro-segmentation, and beyond zero-trust monitoring, I also want to do analysis. However, the product coverage is not very broad, so I have to do my own filtering and analysis, and integration with other tools is necessary. The reporting and analysis are not ready out of the product itself.
Reporting is another area for improvement in this product and is not very sufficient, so I have to further integrate or do it on my own.
Illumio Insights is stable and a mature product. The functionality, such as reporting and analysis, may extend in the roadmap, but it has not in the past. The current functionality is adequate and quite mature, which is how I chose it based on maturity and market share. However, it is not very modern for Kubernetes and containers. If this functionality can extend, that would be a valuable roadmap addition.
Streamline integration with Illumio Insights does not help me much since it does not require too much integration with my other operations.
For how long have I used the solution?
I have been using Illumio Insights for about five years.
What do I think about the stability of the solution?
Illumio Insights is stable and a mature product.
What do I think about the scalability of the solution?
The entire project depends on the scale of my farm. With my farm being not too small and not too big, it took more than one year to implement Illumio Insights because it had to be done in phases. It can affect the application traffic and cause issues. I could not implement it from design to implementation in a short time; it takes a while because it really depends on the scale.
How are customer service and support?
The support is reasonable.
What about the implementation team?
About two people participated in the deployment during this year. I was not directly involved; some team members participated in the deployment process for Illumio Insights.
What other advice do I have?
I would rate this review an 8.

Illumio: #1 A Lighter, Easier-to-Manage Solution for Large Environments
Reviewed on Apr 22, 2026
Review provided by G2
What do you like best about the product?
llumio is seen as a “lighter” and easier-to-manage solution in large environments
What do you dislike about the product?
Illumio still faces challenges to overcome, such as its approach to AI implementation at the K8s level—among other areas of opportunity related to the use of AI itself—but I believe it is on the right track for now.
What problems is the product solving and how is that benefiting you?
Personally, I find that microsegmentation using Illumio is much more user-friendly in terms of installation, configuration, and overall operation compared to other solutions

Easy Deployment, Strong Security Impact, and Great Support
Reviewed on Apr 21, 2026
Review provided by G2
What do you like best about the product?
We implemented Illumio in response to an internal audit. It was easy to deploy, configuration was straightforward, and it makes a measurable impact in our security posture org-wide. The UI is easy to navigate, performance has been very high, and the price is reasonable. Illumio's customer success team has been great to work with and provided prompt support.
What do you dislike about the product?
As with all micro-segmentation tools, it is very easy to make a high-impact bad configuration change. We have to be extremely careful, especially when we have junior engineers operating within the tool.
What problems is the product solving and how is that benefiting you?
An internal audit revealed a weakness in our previous micro-segmentation setup. Illumio addressed this weakness quickly, easily, and comprehensively.

Illuminates Traffic for Enhanced Network Control
Reviewed on Apr 15, 2026
Review provided by G2
What do you like best about the product?
I appreciate Illumio's 'illumination' feature that allows me to map the current traffic to understand communication patterns before applying policies to restrict. The different mappings and dependencies help me understand and have the full picture, which is quite valuable for network segmentation.
What do you dislike about the product?
The adoption journey of Illumio is not that easy. After 1 year, we are still learning to enable some features. I would like my security analysts, network engineers, and sys admins to be able to leverage it. More guided technical workshops, available for customers, to fully adopt the product would be helpful.
What problems is the product solving and how is that benefiting you?
I use Illumio for network segmentation to monitor and control traffic, block lateral movement, and understand communication patterns. The illumination feature maps traffic and dependencies, providing a full picture before applying policies.

Overall, it reduces the blast radius of attacks, simplifies operations, and strengthens security with minimal disruption.
What do you dislike about the product?
Illumio can take time to fully tune, since defining the right policies requires upfront effort.
It focuses on segmentation, so it doesn’t replace other security tools like EDR or firewalls.
The value is highest in complex environments, which may limit impact for very small setups.
Licensing and cost can feel high compared to simpler controls.
Teams may also need training to get comfortable with the model and workflows.
