Illumio is one of only two vendors named a Customers’ Choice, earning a 4.8 out of 5 overall rating and 98% willingness-to-recommend score.
“There is no greater validation for Illumio than the voice of our customers. They’ve been our north star since day one and remain at the forefront of everything we do,” said Andrew Rubin, CEO and Founder of Illumio. “Our newest addition to our AI-driven security platform, Illumio Insights, came about as a direct result of customer feedback and working with our customers as design partners from the very beginning. Our customers are the foundation of everything we do at Illumio.”
Vendors placed in the Customers’ Choice quadrant of the report have scores that meet or exceed the market average for user interest and adoption, and overall experience. Customer feedback consistently highlighted the following strengths of the Illumio Platform:
- Breach Containment: Limits lateral movement and reduces the blast radius of attacks, helping organizations contain incidents quickly and effectively.
- Complete Visibility: Provides instant, granular insight into traffic flows and application communication across hybrid and multicloud environments.
- Ease of Use: Delivers intuitive policy management and rapid deployment, enabling teams to improve security without added operational complexity.
- Scale: Proven to support large, complex environments while maintaining performance and operational simplicity.

The vendor team demonstrated strong expertise in implementation and support ensuring that the platform was aligned with our business and compliance requirements.” IT Security & Risk Management Associate, Insurance
