Adoption of microsegmentation solutions in Enterprise
The research analysis indicated that organizations managing large, heterogeneous technical environments should examine microsegmentation solutions to support their operational readiness.

Several multinational enterprises use the system to manage internal network traffic, including financial institution BNP Paribas, e-commerce company eBay, and technology provider Microsoft. The software is deployed across the entire corporate IT infrastructure at Microsoft to manage access controls and support containment policies. Technical integration across diverse operating systems remains a central focus for organizations adopting microsegmentation solutions to contain digital risks across enterprise software systems and shared digital infrastructure.
“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.”
