About Illumio

Network segmentation: each server may exchange data only with the systems it needs, and an infected machine is cut off with a single command, so ransomware cannot reach its neighbors. Customers include one in five Fortune 100 companies, among them Microsoft.

Illumio was founded in 2013 in Sunnyvale by Andrew Rubin and PJ Kirner; Rubin has remained CEO since day one. The product builds a map of which servers, cloud resources and laptops actually exchange data, and uses it to set rules on who may talk to whom, an approach known as microsegmentation. An attacker who breaks into one machine cannot move further through the network, and an infected node is cut off with a single command. Its customers include one in five Fortune 100 companies; in September 2025 Microsoft publicly confirmed that it had deployed Illumio across its entire corporate IT network, and eBay has segmented more than 3,000 servers. Quarterly bookings reached a record $100 million, and revenue retention is 97%. It has raised $558 million in total over six rounds, at a last valuation of $2.75 billion.

Key highlights

  1. Microsoft: the entire corporate network protected. In September 2025 Microsoft publicly confirmed for the first time that it had deployed Insights and Segmentation across its entire corporate IT network. Microsoft's global chief information security officer called Illumio the only segmentation solution that works at the company's scale.
  2. eBay: 3,000 servers without a single outage. For the first months Illumio ran in observation mode and built a traffic map of 250 applications, then rules were switched on in small batches. Not a single application broke, and incidents are now resolved in minutes instead of hours.
  3. Western Union: isolating acquired companies. The company's network spans more than 200 countries. Illumio keeps the systems of acquired companies separate until they meet security standards and isolates payment servers, which has reduced the scope of PCI DSS audits.
