Illumio Reviews Summary
Author infoRatingReview Summary
Cyber Security Architect at a tech vendor with 10,001+ employees5.0I've used Illumio for two years to implement micro-segmentation based on application roles, finding it effective, scalable, and user-friendly, though it could improve support and automation guidance; it's cost-effective and enhances security visibility significantly.
Senior Security Consultant at Orange Cyberdefense3.0I find Illumio delivers extensive ROI and effective threat containment through its light agent for micro-segmentation. However, it currently lacks Layer 7 process-level segmentation and native container support compared to competing solutions.
DevOps at a marketing services firm with 51-200 employees4.0I use Illumio for EC2 security, finding its east-west traffic control and segmentation effective in reducing lateral movement and improving compliance. While strong, I believe policy management could be more intuitive and automation more advanced.
Cybersecurity Engineer at a tech vendor with 10,001+ employees4.5I find Illumio an excellent, scalable tool for micro-segmentation, offering great traffic visibility and flexible policy management. While stable, I'd like better policy guidance, AI automation, and reduced agent dependency for a perfect 9/10 score.
IT Specialist at Allianz4.0We use Illumio for network micro-segmentation to ensure compliance and security. Its visual traffic interface is invaluable, but manual console upgrades are cumbersome. I can't specify the ROI, but it's the cheapest option among those evaluated.
Assistant Manager at KPMG S.A.4.0I use Illumio in my company to protect our environment and servers, appreciating its valuable features like maps and security build. However, the log collection needs improvement, with more details required on errors or traffic blockages.
Personal business manager at La Mairic4.5In my experience with Illumio at BNP Paribas, its centralized rule distribution is valuable for managing microservices in a hybrid cloud. However, creating effective tagging policies is challenging, and additional guidance in this area would improve its usability.
Technical Consultant at a financial services firm with 10,001+ employees4.0I highly recommend Illumio for micro-segmentation and attack surface reduction. Its auto-policy writing and traffic visibility are excellent. It's stable, scalable, and easy to implement, although customer service needs improvement. I rate it 8/10.
