The world leader in breach containment

Illumio is the first and only platform built for breach containment. Powered by an AI security graph. Enabling your Zero Trust journey.

Breaches are inevitable.
Disasters are optional.

The cloud. Hybrid IT. GenAI. They’re transforming IT environments and expanding the attack surface. Breaches are inevitable. Rather than trying — and failing — to prevent every cyberattack, modern security must focus on reducing the impact of breaches through containment.

Co-founders Andrew Rubin and PJ Kirner started Illumio in 2013 to simplify microsegmentation. With Illumio, organizations can assess their risk, define security controls, and contain cyber breaches before they become disasters — all at cloud scale.
