Cyber-physical systems (CPS) protection company Claroty has announced it has raised $150 million in a Series F funding round, led by Golub Growth, an affiliate of Golub Capital. Existing investors also participated, contributing up to an additional $50 million. 
This substantial investment is set to propel Claroty’s global growth efforts, both through organic expansion and acquisitions, as the company advances its mission to develop the industry’s most comprehensive CPS security platform.
The importance of this funding is underscored by growing concerns over cyber attacks targeting critical infrastructure. Gartner® highlights that with the rise of CPS, ransomware and other cyber threats originating in the digital realm now threaten physical assets such as oil pipelines, water utilities, and food processing facilities. These sectors are increasingly vulnerable, especially amid rising geopolitical tensions and the interconnected nature of critical infrastructure, national security, and economic stability.
The market for CPS protection has matured rapidly in recent years, driven by heightened awareness of these threats. However, security leaders face significant hurdles in safeguarding CPS environments. Challenges include unclear ownership roles between IT and operational technology (OT) teams, the absence of maturity models or success benchmarks, and a shortage of skilled personnel and resources. These issues leave essential operations at risk, emphasizing the urgent need for robust and integrated security solutions.
Yaniv Vardi, CEO of Claroty, emphasized the company's strategic approach: “Organizations need a platform approach that serves as the foundation of a holistic CPS protection program, leveraging the right combination of technology, people, and processes to reduce risk, ensure compliance, and maintain operational integrity.” He added that Claroty’s deep expertise and advanced technology uniquely position it to help organizations meet these challenges. The new funding marks a significant milestone in Claroty’s growth trajectory and demonstrates confidence in its ability to secure critical cyber-physical systems that underpin daily life.
Rob Tuchscherer, Senior Managing Director at Golub Capital, expressed enthusiasm about the partnership: “Golub Growth is proud to partner with Claroty to help accelerate the growth of its proven solutions, which leverage unparalleled CPS domain expertise and a trusted platform to meaningfully reduce risk for customers. We’re excited to support the Claroty team as they scale to address the evolving needs of a dynamic and growing market.”
