What happened
Israeli cybersecurity firm Claroty announced it has raised $150 million in a Series F funding round, boosting its valuation to approximately $3 billion. The funding, led by Golub Growth with participation from existing investors, aims to accelerate global expansion and enhance the company’s cybersecurity platform for industrial and critical infrastructure systems. Claroty also highlighted a marked increase in cyberattacks on sectors like hospitals and manufacturing.
Who is affected
- Critical infrastructure operators (hospitals, industrial facilities, manufacturing) facing increased cyber threats.
- Security teams and CISOs responsible for protecting operational technology (OT) and cyber–physical systems (CPS).
- Investors and technology partners in the cybersecurity ecosystem, given Claroty’s expanded footprint and investor backing.
Why CISOs should care
- Rising attacks on critical systems: Claroty cites a sharp uptick in attacks on hospitals and industrial networks, indicating growing threat activity against OT environments that are often less monitored and harder to secure than IT networks.
- AI-driven threats: The company notes attackers increasingly leveraging AI for faster, more sophisticated intrusion campaigns, suggesting the threat landscape is evolving in complexity.
- Strategic investment signal: Significant venture funding into OT/critical infrastructure security underscores broader market recognition that protecting these environments is a priority, and an emerging challenge for security leaders.
3 practical actions
- Assess OT Visibility Gaps: Conduct or update discovery of OT and CPS assets within your environment to ensure you understand where blind spots may exist, particularly in hospitals, manufacturing lines, and industrial control systems.
- Align IT and OT Security Teams: Strengthen collaboration between IT and OT cybersecurity teams to share threat intelligence, coordinate defenses, and ensure consistent incident response across both domains.
- Monitor for AI-Enhanced Threats: Update threat detection and analytics tools to look for indicators of AI-driven attack patterns and anomalous behavior in both IT and OT traffic, adjusting rules and playbooks accordingly.
