Illumio Named a Leader and a Customer Favorite in Microsegmentation by Leading Independent Research Firm

Research states organizations with large, heterogeneous environments focused on improving cyber resilience should consider Illumio

SUNNYVALE, Calif., Aug. 18, 2026 (GLOBE NEWSWIRE) -- Illumio Inc., the breach containment company, today announced it has been named a leader in The Forrester Wave™: Microsegmentation Solutions, Q3 2026 report. Illumio received the highest scores among all evaluated vendors in both the Current Offering and Strategy categories and was named a “Customer Favorite” for its outstanding customer feedback among evaluated vendors. According to the report, “Repeat customers indicate their satisfaction with the consistently high quality of technical support, regardless of the personnel assigned to their account.”

The report evaluated 10 microsegmentation providers against a comprehensive set of criteria covering product capabilities, strategy, innovation, and customer experience. Illumio received the highest scores possible in 10 evaluation criteria, including areas related to visualization, host-based enforcement, product security, vision, and innovation. According to the report, “Illumio excels at essential microsegmentation functions.”

“Illumio was founded on a simple belief: breaches are inevitable, but cyber disasters are not. We have been singularly focused on one objective — reducing lateral movement and attack surface, and increasing resilience in every organization,” said Andrew Rubin, CEO and Founder of Illumio. “Being named both a Leader and a Customer Favorite reflects to us the strength of our technology, vision, and even more importantly our ability to deliver real outcomes and risk reduction, which is the foundation of the trust our customers place in us every day. In the model threat world we are all now entering, defense must be coupled with resilience. Recovery is the new defense — and the new cyber.”

According to the Forrester Research report, “Organizations with large, heterogeneous environments focused on improving cyber resilience should consider Illumio.” The report also recognized Illumio for:

• “Illumio has articulated a vision for microsegmentation as a core element of security operations.”
• “Illumio is bridging the gap between its traditional users and other parts of the security organization by delivering agents mapped to personas from other teams.”
• “Its UI provides easy access to information that supports both access control and incident response use cases.”
  
  

The recognition follows continued innovation across the Illumio Platform, including Network Posture, which helps organizations understand security posture based on real-world traffic and prioritize risk reduction efforts. These capabilities support the growing need for visibility, cyber resilience, and regulatory readiness across complex hybrid and multi-cloud environments.

Designed for operational simplicity, the Illumio Platform combines Illumio Insights and Illumio Segmentation to help organizations identify, assess, and contain cyber risk across hybrid and multi-cloud environments. Security teams can uncover high-risk exposures, visualize potential attack paths, and implement segmentation policies from a single platform to contain threats and improve cyber resilience.

The platform is trusted by some of the world's largest organizations, including BNP Paribas, eBay, and Microsoft, the latter of which has deployed Illumio Insights and Illumio Segmentation across its entire corporate IT environment. Igor Tsyganskiy, Global CISO of Microsoft, said: “When we needed to bring these capabilities into Microsoft, Illumio was the only segmentation solution that would work at the scale of Microsoft and deliver in our environment.”
