Illumio can be improved if we have more interactive sessions with the tech team. The support of Illumio can be better since it's a new tool, and people can explore it more. There could also be more examples of how the automations can be done using Illumio.

Illumio does not have much in terms of application dependency mapping features. They lack layer 7 process level segmentation, which is a limitation.
In Guardicore, you have the layer 7, the process level. You don't have that in Illumio. This indicates that the information about malware, intrusion detection, and threats would be better in Guardicore because it has this layer 7 support which Illumio does not have.
Some customers like Illumio because it's a simpler product. If it's too complex, some customers think that it's better to have a more simple product. Of course, Illumio has some features that Guardicore doesn't have.
The container support in Illumio is not the same as in Guardicore.
Guardicore has native support for containers, but Illumio does not have native support. They need to install an agent in the container world, while Akamai Guardicore does not need to install an agent, so they have native support that Illumio lacks.
View full review »One area for improvement regarding Illumio might be making the policy management even more intuitive. Right now, it's powerful but can have a bit of a learning curve for some teams. Another thing could be deeper integrations with more third-party security tools. While they do integrate well, a broader set of APIs could make it even easier to slot into different stacks. It is already strong, but a bit more polish on usability and integration could take it further.
Another improvement might be around scalability, ensuring that as organizations grow, Illumio can handle even larger, more complex environments seamlessly. It would be great to see more advanced automation, such as AI-driven recommendations on segmentation rules or anomaly detection. That would really boost proactive security management.

Illumio requires me to create policies for each type of traffic, and for new users, the policy design can be a bit complex. More guided onboarding or automatic policy suggestions would help teams adapt to Illumio faster without needing extensive expertise. While I do not find issues with the interface, first-time users might struggle with navigation. Current limitations also include the integration with tools such as SIM not being seamless, and support for Splunk and Sentinel could be improved. More AI automation in policy creation, such as auto policy recommendations and anomaly detections, would reduce manual processes and human errors. Additionally, old operating systems may not be fully supported, and broader compatibility for the agent or an agent-less option would be beneficial.
Enhanced reporting and analytics would be useful, as current reporting is basic, so improvements such as more customizable reports, compliance reports, and executive dashboards are needed due to their use for management and audits. Reducing dependency on the agent is crucial since enforcement depends on agent health, so improvements such as a backup enforcement mechanism and better agent monitoring or auto-recovery would increase reliability.

View full review »The log collection part needs improvement, and the tool should offer more details about the logs. 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.
Some of the features that can be improved is offer additional guidance on creating an effective and risk-free tagging policy would be highly beneficial.

Every month, we're getting new features. It's always improving. I don't see a place where it is weak or lacking in development.
The customer service is lagging a bit. It could be better.
We'd like labeling to be better. For example, if someone, by mistake, if he edits that labeling part, it should give you a warning pop-up to the effect of "Are sure to edit this enforced application?" so that person immediately will know that this is the enforced application and he should not touch that application labeling.

Illumio Adaptive Security Platform could improve by supporting more operating systems. For example, Cisco and Apache appliances.

View full review »The solution is very basic and doesn't do anything other than the orchestration of layer four endpoint firewall rules.
View full review »The product’s agents don't work very well in OT environments. It could include environments with manufacturing sensors or other devices where installing the agent may not be possible. We don't have the same visibility and flexibility that we have on our computer or server.
View full review »The interaction we've had with the support team hasn't been ideal. Technical support should be improved.
The solution needs to better integrate before we are able to deploy. It would be helpful if we could deploy the solution even if there are difficulties with integrations or other conflicts.

No. The product has great future-proof vision. The additional features are being added throughout the period to cater different scenarios.
