Investment from Golub Growth, a subsidiary of Golub Capital, to drive global expansion and development of comprehensive CPS security platform

Claroty, a specialist in cyber-physical system (CPS) security, has secured £150 million in Series F funding. The funding round was led by Golub Growth, a subsidiary of Golub Capital, and includes additional participation from existing investors of up to $50 million. This new investment will drive global expansion through organic and inorganic growth as the company continues to pursue its ambitious vision of building the industry’s most comprehensive CPS security platform.

According to Gartner, “With the growing adoption of CPS, ransomware and other cyber attacks originating in the cyber world are increasingly and demonstrably impacting physical assets such as oil pipelines, water utilities, and meat processing plants. This is particularly true in critical infrastructure sectors, as geopolitical risks increase and there is a direct link between critical infrastructure, national security and economic growth.”*

Growing awareness of the dangers of cyber attacks on critical infrastructure has led to rapid maturation and advancement of the CPS security market in recent years. Nevertheless, security managers responsible for protecting cyber-physical systems still face a number of major challenges, such as unclear responsibilities between IT and OT teams, a lack of maturity models or roadmaps to measure progress, and insufficient skills and resources. All of this complicates their work and often results in inadequately protected business-critical processes.

‘Companies need a platform approach as the basis for a holistic CPS security programme. This must intelligently combine technology, people and processes to reduce risk, maintain compliance and preserve operational integrity,’ explains Yaniv Vardi, CEO of Claroty. “With our comprehensive knowledge of CPS processes and networks and the most advanced technology on the market, we are ideally positioned to help companies achieve these goals. The new funding marks the beginning of an exciting new chapter in Claroty’s growth story. We are delighted to have Golub Growth join us on our journey to protect the cyber-physical systems that are the foundation of our daily lives.”

‘Golub Growth is proud to partner with Claroty to further accelerate the growth of its proven solutions, which are based on unparalleled expertise in CPS and Claroty’s proven platform, significantly reducing risk for customers,’ said Rob Tuchscherer, Senior Managing Director at Golub Capital. ‘We look forward to supporting the Claroty team as it expands to successfully address the changing needs of a dynamic and growing market.’
