Claroty, a cybersecurity firm specializing in protecting cyber-physical systems (CPS), announced Wednesday it has raised $150 million in Series F funding, led by Golub Growth, an affiliate of Golub Capital.
Up to $50 million of the funding comes from existing investors, and the investment will support Claroty’s continued global expansion, both organically and through potential acquisitions.
The company aims to accelerate development of its CPS protection platform, which is designed to secure critical infrastructure across sectors such as energy, water, healthcare and manufacturing—areas increasingly targeted by cyberattacks with physical-world impact. Claroty’s platform covers exposure management, network protection, secure access and threat detection, across both cloud and on-premise environments.
“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 in order to reduce risk, maintain compliance, and preserve operational integrity,” said Claroty CEO Yaniv Vardi. “With the deepest knowledge of CPS operations and networks and the most advanced technology in the market, Claroty is uniquely positioned to help organizations achieve these outcomes.”
The funding comes amid growing threats to critical infrastructure, highlighted in a Gartner report noting that ransomware and other cyberattacks increasingly target physical assets such as oil pipelines, water utilities and food production facilities, raising national security and economic concerns. While the CPS security market has rapidly matured, Claroty notes that organizations still face challenges such as blurred ownership between IT and OT teams, skill shortages and lack of clear maturity models.
Rob Tuchscherer, Senior Managing Director at Golub Capital, said Claroty’s solutions “leverage unparalleled CPS domain expertise and a trusted platform to meaningfully reduce risk for customers,” adding that Golub is proud to support the company’s next phase of growth.
Claroty’s momentum over the past year includes an 80% increase in company valuation since its last funding round in March 2024 and a customer base that now includes 24 of the Fortune 100. The company recently launched the CPS Library, an AI-powered asset catalog developed in collaboration with Schneider Electric and Rockwell Automation to improve asset visibility and tracking.
Claroty has also strengthened its leadership team with the appointment of former Ford AI chief Gil Gur Arie as Chief Product Officer and expanded its partnerships across the tech sector, including new collaborations with Google Security Operations and AWS.
In the public sector, the company appointed retired U.S. Air Force Colonel Jen Sovada to lead its government efforts and launched integrations with defense contractors and federal IT providers to advance support for U.S. Intelligence Community needs.
The company has earned major analyst recognition in 2025, being named a Leader in the Gartner Magic Quadrant for CPS Protection Platforms and in Forrester’s Wave for IoT Security Solutions.
Claroty is deployed across thousands of sites worldwide and operates globally with offices in Europe, Asia-Pacific, Latin America and its headquarters in New York City.
