Illumio Breach Containment Platform
Illumio Zero Trust Segmentation (ZTS) Platform is the only solution that handles it all: Endpoint-Endpoint, Endpoint-Server, Server-Server, as well as extensive support for cloud workloads, containers, IoT, and OT devices. Empowering organizations to be more resilient for whatever may come their way. ZTS contains the spread of breaches and ransomware across the hybrid attack surface by continually visualizing how workloads and devices are communicating, creating granular policies that only allow wanted and necessary communication, and automatically isolating breaches by restricting lateral movement proactively or during an active attack.
In addition, Illumio ZTS includes the Illumio Virtual Advisor (IVA) which provides actionable, AI driven guidance for even the most complex tasks. With IVA, teams can streamline their workflows with instant, expert-level answers to their questions. Quickly access critical information and achieve complex tasks simply by asking the virtual advisor.

Smooth Implementation Without Impacting Production
Reviewed on Aug 12, 2026
Review provided by G2
What do you like best about the product?
Implementation, with the right methodology doesn't impact production.
What do you dislike about the product?
It wasn't an fancy product in the past but this has changed with the AI tools. So there is nothing i really dislike.
What problems is the product solving and how is that benefiting you?
It solve the issue of limiting the lateral movement and reducing the blast radius. It can also help identifying abnormal traffic and rogue actor movements.

Strengthening Zero Trus with Workload Visibility and Microsegmentation
Reviewed on Aug 12, 2026
Review provided by G2
What do you like best about the product?
What I like best about Illumio is its ability to provide clear visibility into workload communications and enable granular microsegmentation without relying heavily on traditional network boundaries. The label-based policy model makes it easier to manage segmentation across complex hybrid environments, while providing strong control over east-west traffic and reducing lateral movement risk.
What do you dislike about the product?
One area that could be improved is the workload management experience. For example, the Workloads page does not make it easy to search for or work with multiple specific workloads at the same time, which can be inconvenient when managing a large environment.
Additionally, reporting and bulk operational tasks could be more flexible, especially for larger deployments. More advanced filtering, easier bulk actions, and better customization of dashboards and reports would improve the overall day-to-day operational experience.

What problems is the product solving and how is that benefiting you?
Illumio helps address the challenge of controlling east-west traffic and reducing lateral movement across a complex hybrid environment. It provides visibility into workload-to-workload communication and allows us to apply granular segmentation policies based on labels rather than network boundaries. This helps strengthen our Zero Trust approach, reduce exposure to risky or unnecessary traffic, and provide better control during security incidents without requiring major changes to the underlying network architecture.

Well-Architected Platform That Streamlines Onboarding and Micro-Segmentation
Reviewed on Aug 11, 2026
Review provided by G2
What do you like best about the product?
Illumio is a very well-architected platform, and it has made our onboarding process efficient and straightforward.
The approach of applying different labels to each workload, and then using those labels to understand and visualize traffic and write the right policies around it, has really sped up our deployment of micro-segmentation in our environment.

What do you dislike about the product?
The Rule Sets/Policies are written with the destination in mind, so it’s straightforward to create policy for apps that have Illumio VEN Agents installed and allow traffic into those apps/workloads. This is done by defining the Scope for the Rule Set.
It’s a bit trickier to write “outbound” Rule Sets when your workloads need to send network traffic to an app that doesn’t have a VEN Agent, since there isn’t a Scope for those types of destinations as some may not be consider to be "Workloads".

What problems is the product solving and how is that benefiting you?
Illumio is solving three problems for us. At its core, it helps protect our applications and workloads by allowing only the network traffic that is intended to and from those workloads, and nothing else. As a result, it gets us much closer to Zero Trust.
The second benefit is the visibility we gain. Being able to see the network traffic makes it easier to build application traffic maps and dependency maps for both on-prem and cloud workloads.
The third problem it’s solving is that, by understanding network traffic and analyzing risky traffic, it can suggest ways to improve our security posture by closing down ports the platform identifies as risky (for example, common ports used by ransomware).
