The leader in Zero Trust Segmentation

Welcome to the breach containment era
In this time of increasing ransomware and cybercrime, Illumio provides the only proven segmentation product suite purpose-built for Zero Trust security.
We believe all organizations should be able to thrive with confidence, assured their digital infrastructure and assets are safe.
To achieve this goal, co-founders Andrew Rubin and PJ Kirner started Illumio in 2013 to build remarkably easy-to-use security technology that stops hackers and malware from moving laterally through networks.
A security architecture for modern threats
Detection and perimeter defenses are no longer enough. You will be breached.
Flat networks without segmentation are defenseless against ransomware and cyberattacks. Once in, attackers and malware can move where they please. We stop that.
Built for modern threats, Illumio has pioneered an unprecedented way to contain and minimize the impact of breaches and ransomware. Illumio provides a consistent approach to Zero Trust Segmentation (ZTS), including microsegmentation, across the hybrid attack surface.
With Illumio ZTS, you can:
- Proactively and reactively contain ransomware.
- Identify and close high-risk pathways and ports.
- Strengthen your incident containment capabilities.
- Isolate and protect high-value applications and databases.
Stop the spread of ransomware and breaches. That's what we do.
