About the Company

Illumio

Adaptive security platform for micro-segmentation

Illumio provides adaptive cybersecurity for large enterprises, offering the Adaptive Security Platform (ASP) that secures data centers and cloud environments. The platform delivers visibility, security, and encryption by segmenting enterprise networks into small, isolated parts (micro-segmentation). This containment limits breach spreading, so if one segment is compromised, others stay secure. The product works as a subscription service, with ongoing access to the platform and services, and benefits from updates and partnerships with leading technology providers. Illumio differentiates itself through its focus on adaptive security and micro-segmentation across both on-premises data centers and cloud, backed by a track record of awards and leadership. The company’s goal is to help large organizations prevent cyber threats and protect sensitive data by making networks smaller, more manageable, and harder to breach.
