Illumio Secures $225 Million at $2.75 Billion Valuation to Stop Cyber Disasters with Zero Trust Segmentation


Illumio, the pioneer and leader of Zero Trust Segmentation, today announced a $225 million Series F funding round at a $2.75 billion valuation. The round is led by Thoma Bravo and is also supported by Franklin Templeton, funds managed by Hamilton Lane, and Owl Rock, a division of Blue Owl Capital.

Cyberattacks and ransomware are more successful than ever. We are witnessing the most catastrophic breaches in history on a regular basis, despite security spending that is expected to top $150 billion* this year. Colonial Pipeline, JBS, Microsoft Exchange and daily incidents of smaller ransomware payouts prove that legacy security does not provide adequate protection, and the entire security model is in question. A Zero Trust strategy is the new model, designed to assume breach at all times. While no single product or platform equals a complete Zero Trust approach, segmentation is a core pillar of every Zero Trust strategy.

Illumio pioneered Zero Trust Segmentation, and the company’s SaaS platform makes it easy to deliver automated enforcement in minutes, dramatically reducing risk by stopping successful cyberattacks and ransomware from moving to other applications, clouds, containers, data centers, and endpoints. Many Fortune 100 companies and hundreds of global enterprises are using Illumio today, including the three top enterprise SaaS companies, five of the leading insurance companies, and six of the ten biggest banks in the world.

“Adopting Zero Trust strategies has never been more important for organizations across all industries, as the Biden Administration’s recent cybersecurity Executive Order demonstrates. This investment signals that now is the time to reimagine the cybersecurity model as we know it, with Zero Trust Segmentation playing a fundamental role in this strategic shift,” said Andrew Rubin, CEO and co-founder of Illumio. “With this funding, we will accelerate our innovation in product and engineering, further invest in customer success, and build upon our global partner strategy.”

Illumio provides fast, simple, cloud-native Zero Trust Segmentation. Illumio Core and Illumio Edge make it easy to segment your hybrid, multi-cloud IT estates and to secure workloads at any scale, from 100 to 100,000+ workloads. Illumio delivers intelligent visibility, a radically simple policy creation engine, and automated segmentation and enforcement in minutes. Illumio’s unique approach to stopping the spread of cyber disasters has fueled the fastest period of growth in company history with highlights including:


“As the volume and sophistication of cyberattacks increases, Zero Trust Segmentation is set for a breakthrough moment, and Illumio is the clear market leader,” said Robert (Tre) Sayle, a partner at Thoma Bravo. “Illumio plays a critical role in protecting some of the largest organizations in the world and is well-positioned to build upon its record-breaking growth with continued sales momentum and product innovation. We look forward to partnering with the talented Illumio team and leveraging Thoma Bravo’s significant security and operational expertise as we embark on an initiative to invest in hyper growth software and technology companies.”
