Claroty raises USD $150m to boost CPS cyber security

Claroty has raised USD $150 million in a Series F funding round led by Golub Growth, with further participation from existing investors of up to USD $50 million.

The company focuses on cyber-physical systems security, an area that covers operational technology environments and connected physical assets used in sectors such as manufacturing, utilities and transport. Claroty said the financing supports its next phase of global expansion and revenue growth.

Golub Growth is an affiliate of Golub Capital and invests in growth-stage business-to-business software companies. Claroty did not disclose other participating investors in the round.

Claroty positioned the funding against a wider increase in cyber incidents affecting critical infrastructure. It cited research from Gartner on cyber attacks that cross from digital systems into physical assets.

Market pressures

Claroty said the market for cyber-physical systems protection has matured as awareness of attacks on critical infrastructure has grown. The company pointed to common organisational issues in cyber-physical systems security programmes. It listed unclear ownership between IT and operational technology teams, limited skills and resources, and the absence of a maturity model or roadmap.

"Organisations 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 Yaniv Vardi, CEO, Claroty.

Claroty described its product direction as a platform approach for cyber-physical systems environments. It referred to this area as mission-critical operations.

Customer base

Claroty reported customer growth over the past year and said it now works with 24 Fortune 100 organisations. The company did not name the customers in that group.

It also reported an 80% increase in valuation since its previous financing round in March 2024. Claroty did not disclose the valuation figure or the size of the earlier round in the same announcement.

Product activity

The company pointed to several product and partnership developments. It said it hired Gil Gur Arie, previously AI Chief at Ford Motor Co., as Chief Product Officer.

Claroty also launched the CPS Library. It described the product as an AI-powered asset catalogue. The company said the catalogue improves visibility and accuracy when tracking asset specifications. Claroty said it worked with Schneider Electric and Rockwell Automation on the initiative.

In cloud and security ecosystem work, Claroty said it achieved the AWS Manufacturing and Industrial Competency for OT Security. It also announced a strategic collaboration with Google Security Operations.

Public sector

Claroty highlighted activity in government and defence-related markets. It said it appointed retired U.S. Air Force Colonel Jen Sovada to lead its public sector team.

It also announced an integration with Parsons' SealingTech. Claroty said it added FISMA support with STIG-hardened configuration management controls to Claroty Continuous Threat Detection.

The company also said it launched a partnership with Mission IT. It linked the relationship to its entrance into the U.S. Intelligence Community.

Analyst recognition

Claroty said analysts recognised the company in several reports over the past year. It said Gartner named it a leader in the 2025 Gartner Magic Quadrant for CPS Protection Platforms. It also said Forrester named it a leader in The Forrester Wave: IoT Security Solutions, Q3 2025.
