Cyera bets big on AI data security with $400M round and $9B valuation

Cyera, an AI data security company, has raised $400 million in a Series F funding round, pushing its valuation to $9 billion. Founded in 2021 by Yotam Segev and Tamar Bar-Ilan, both veterans of Israel’s elite military intelligence units, Cyera specializes in AI-driven solutions that help organizations discover, classify, and protect sensitive data across complex environments. The company’s platform currently serves around 20% of the Fortune 500, including firms in financial services, healthcare, retail, technology, and telecommunications.

This significant funding round nearly doubles Cyera’s total capital raised to over $1.7 billion and highlights the growing demand for cybersecurity solutions tailored to the challenges posed by AI integration and cloud migration. Cyera’s AI Guardian platform integrates data security posture management, data loss prevention, and identity controls to continuously detect risks and safeguard sensitive information across enterprise data systems.

The new capital will accelerate Cyera’s product innovation, particularly in agentic AI security—addressing emerging risks from autonomous AI behaviors by monitoring access, usage, and deviations to ensure AI agents operate within intended boundaries. Strategic partnerships with cloud providers such as Microsoft, AWS, and Cohesity reinforce Cyera’s expanding ecosystem.

As enterprises increasingly rely on AI systems that handle critical and sensitive data, Cyera’s role in providing a comprehensive control plane for AI data governance becomes vital, highlighting the company’s positioning at the forefront of AI-driven data security innovation.
