AI and data security company Cyera announced a $400 million Series F funding round on Thursday. This brings the total money the company has raised to over $1.7 billion. The funding round was led by Blackstone and included support from existing investors like Accel, Sequoia Capital, Coatue, Lightspeed, and others.
This new investment comes just over six months after Cyera’s last funding round and increases the company’s valuation to $9 billion—three times higher than it was a year ago.
The fast growth shows that companies are in a hurry to protect their data as AI use spreads quickly. Agentic AI, which can make decisions on its own, is becoming popular in many industries.
Cyera was founded in 2021 by Yotam Segev (CEO) and Tamar Bar-Ilan (CTO), both graduates of the elite Talpiot program and former members of Unit 8200. The company builds an AI-powered platform that helps organizations find, organize, and protect sensitive data wherever it is stored.
In June last year, Cyera bought another Israeli company, Otterize, which focuses on protecting non-human identities in cloud systems, in a deal worth tens of millions of dollars. This was Cyera’s third Israeli acquisition, after also buying Trail Security in October 2024 and adding it to its platform. So far, Cyera has spent around $250 million on acquisitions in Israel.
“AI is reshaping the foundations of how every organization operates, and our mission is to ensure that this transformation happens securely,” said Segev. “Enterprises want to move quickly, but they also recognize that AI without data security and governance is a risk they cannot afford. Securing AI isn’t just a technology challenge, it’s the new cornerstone of enterprise trust.”
Over the past year, Cyera has grown quickly. It now protects data and AI systems for about 20% of the Fortune 500, including big companies in finance, retail, healthcare, technology, and telecom.
The company’s team has tripled to more than 1,100 employees, and Cyera now operates in 15 countries across North America, Europe, the Middle East, Africa, and Asia-Pacific.
