Illumio is led by co-founder and chief executive Andrew Rubin, who has guided the company since its founding in 2013. The leadership team combines founders with experience across networking, virtualization, and enterprise security.
Independent analyst recognition reinforces that position, with Illumio named a Leader and a Customer Favorite in the Forrester Wave for Microsegmentation in the third quarter of 2026. The combination of founder-led continuity and third-party validation differentiates Illumio in the segmentation market.
Illumio has raised about 582.5 million dollars across its venture history, including a 225 million dollar Series F round in June 2021 at a 2.75 billion dollar valuation. Backers include Andreessen Horowitz, Accel, General Catalyst, 8VC, and Thoma Bravo.
The funding trajectory tracks the growth of the microsegmentation category from early zero-trust networking into mainstream enterprise breach containment. Continued investment supports platform expansion across cloud, endpoint, and data center workloads.
