Competitors
Fortinet
Broader network security portfolio but less specialized in passive OT monitoring and CPS-specific threat detection.
Nozomi Networks
Competing OT security player with network-based monitoring; lacks Claroty's integration with IT security infrastructure and secure remote access capabilities.
Tenable
Broader vulnerability management platform; less specialized in operational technology and passive network monitoring approaches.
Why this matters: Claroty has raised $882M from top-tier investors including SoftBank Vision Fund 2 and Bessemer Venture Partners, making it one of the most heavily-funded industrial cybersecurity companies. The company's founding from Team8 (Israeli cyber venture studio) combined with founders' expertise from Siemens, IBM, and Israeli Defense Force positions it as a category leader in the critical OT security market.
Best for: Critical infrastructure operators in energy, manufacturing, pharma, and utilities that need comprehensive OT asset visibility and threat detection without disrupting production systems.
Use cases
Vaccine Supply Chain Security
Pfizer used Claroty to secure its COVID-19 vaccine supply chain manufacturing and distribution network. The platform provided visibility into critical production systems without requiring active scanning that could interrupt production during high-demand periods.
Industrial Manufacturing Asset Discovery
Automotive manufacturers use Claroty's passive monitoring to discover and track all connected industrial assets including robots, PLCs, and SCADA systems. The agentless approach allows continuous monitoring without installing software on operational controllers.
Multi-Site Enterprise OT Governance
Fortune 100 industrial companies use Claroty's Enterprise Management Console to centrally monitor and manage OT security across dozens of geographically distributed facilities, integrating risk intelligence with existing corporate security tools.
