Illumio Reviews & Product Details

Illumio is helpful because it stops attackers from moving around your network if a breach happens.

It uses Zero Trust segmentation to limit access without needing major network changes.

You get clear visibility into application traffic across data centers and cloud environments.

It’s quick to deploy, easy to manage, and scales well as your environment grows.

Overall, it reduces the blast radius of attacks, simplifies operations, and strengthens security with minimal disruption. Review collected by and hosted on G2.com.

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. Review collected by and hosted on G2.com.

My org uses Illumio for intra-VLAN protection, ransomware blast radius reduction, and as a more flexible alternative to our mess of ACLs.

It's letting us reduce our ACL sprawl, which was nearing hardware limits (CAM table exhaustion).

Illumio’s policy model and VEN install are baked into our server deployment process now, which I recommend all customers do.

I work in both networking and security, and Illumio bridges both worlds well. I touch it frequently to manage access across all sorts of servers and traffic flows, and I have no complaints about performance or UI.

Great for network or security folks trying to shrink blast radius and ditch legacy ACL messes. Review collected by and hosted on G2.com.

There is definitely a learning curve, but once you wrap your head around the policy model, it clicks.

Only gotcha I've seen is that changing a server IP often requires reinstalling the VEN. Review collected by and hosted on G2.com.

Illumio is the best product we use as a company IT-wise. It literally keeps us safe and is a tremendous troubleshooting tool as well! It is extremely easy to use, and tagging our servers via the import csv utility is a great feature we've come to love. Review collected by and hosted on G2.com.

Sometimes it works "too" good, but that is why we have it. It locks down traffic like it's supposed to! Review collected by and hosted on G2.com.

The microsegmentation is its biggest feature. What I like most is the ease in configuration and implementation. Troubleshooting can be done faster as the configuration is simple and easy to understand Review collected by and hosted on G2.com.

None. When compared to other firewalls, Illumio is the easist to implement and troubleshoot. Review collected by and hosted on G2.com.

I love Illumio for its ease of implementation, which simplifies integrating the system into our network environment. This feature significantly reduces the time and resources needed for setup. Moreover, I appreciate that Illumio efficiently organizes communications in a way that enhances security and essentially eliminates the risk of lateral movement, providing a robust defense against potential cyber-attacks. Additionally, the quality of after-sales support offered by Illumio is commendable, as it ensures continuous assistance and resolution of any issues that may arise post-implementation, thereby enhancing the overall user experience.

I find compatibility with legacy operating systems to be lacking. Review collected by and hosted on G2.com.

Illumio is among the most impressive technologies I have encountered for supporting a zero trust approach. It greatly simplifies the process of implementing micro-segmentation. Review collected by and hosted on G2.com.

I think there is always potential for improvement. My main issue is the inability to stream logs directly to a SIEM, which I find limiting. Aside from that, I consider it to be an excellent product. Review collected by and hosted on G2.com.

Illumio is a key technology in our journey to zero trust by enforcing least-privilege across our workloads.

The dynamic laelling means we can deploy micro-segmentation quickly and at scale.

By implementing Selective Enforcement as a first phase we can achieve an initial level of segmentation quickly across our assets.

The move to a Unified console where one can have visibility and enforcement of policies across both on-premise adnd cloud assets.

By leveraging the Illumio API we have a robust integration with many internal systems for automation including our CMDB, IP Management tools, virtualization platform and directory services. Review collected by and hosted on G2.com.

High utilization of Memory on some servers by the Illumio agent.

Some issues with performance of the SaaS console although this seems to have been improved since moving to a dedicated instance.

Some issues experienced with the visualization of logs in explorer.

Would like to see a clearer schedule on our move to the Unified console. Review collected by and hosted on G2.com.
