llumio is seen as a “lighter” and easier-to-manage solution in large environments Review collected by and hosted on G2.com.

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. 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.

It is a great tool --- it delivers strong, identity‑based micro‑segmentation. And it helps to reduce lateral‑movement risk and eventually helping security teams enforce policies with confidence. 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.
