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.

  • See your risks

    Uncover security vulnerabilities with a comprehensive and crystal-clear view of the communication flows for your applications and data.

  • Isolate breaches

    Take rapid action to build your cyber resilience. Safeguard critical assets to protect your business against ransomware and cyberattacks.

  • Secure your data

    Drive Zero Trust protection across your digital infrastructure by automatically, efficiently and safely enforcing least-privilege security policies.

“I really see Illumio as not just a security tool or a zero trust or a micro segmentation or a ransomware protection capability or a post response toolkit that you would want to use. I see it as an asset that can bring the technology function together so that the availability of the necessary technology for the business to be successful is there, and that it's being continually improved upon and protected through control, such as Illumio.”
