New York-based alternative investment management company Blackstone is leading a $400 million investment in Cyera, an Israeli tech startup that helps businesses classify and protect data across multiple environments, according to a report by The Wall Street Journal.
Founded in 2021 by CEO Yotam Segev and CTO Tamar Bar-Ilan, Cyera is also backed by venture capital firms Sequoia Capital and Accel.
Segev and Bar-Ilan are graduates of the Israel Defense Forces’ Talpiot program and Unit 8200, known for producing officers with exceptional scientific aptitude and leadership potential.
Cyera raised $540 million in a funding round in June that doubled its valuation to $6 billion. Before that round, the company had raised approximately $760 million.
Cybersecurity is one of Israel’s largest tech sectors, with nearly $5 billion raised across more than 130 funding rounds in 2025—a 46% increase compared to 2024.
In June, Cyera reported 353% growth among Fortune 500 customers over the previous 18 months, expanded into 10 countries, and more than doubled its workforce to nearly 800 employees worldwide.
