Cybereason is an Israeli-founded cyber-security company that sells extended detection and response (XDR), digital-forensics and incident-response services. It was founded in 2012 by Lior Div, Yonatan Striem-Amit and Yossi Naar.[1] The managed-security provider LevelBlue completed its acquisition in November 2025.[2]
Founders and Unit 8200
Yonatan Striem-Amit told Safety Detectives: "When I was 18, I was chosen for the 8200 intelligence unit of the Israel Defense Forces (IDF) as a 'PC kid'" (Unit 8200; Israel Defense Forces). He called the unit "absolutely the best environment in the world for kids like me who had the aspirations, knowledge, and a lot of free time to turn them into cyber entrepreneurs".[3]
Decline and sale
Ctech reported that Cybereason's valuation peaked at around $3 billion in a July 2021 funding round, then fell to about $300 million within a year. It cut jobs in three rounds between 2022 and 2024. A merger agreed with Trustwave in November 2024 did not go ahead. In 2025 it received a $120 million emergency investment led by SoftBank and Liberty Strategic Capital. This came amid boardroom disputes and a lawsuit in which former chief executive Eric Gan "accused the company’s largest investors of obstructing financing efforts to consolidate control".[1]
On completion of the LevelBlue deal, SoftBank, SoftBank Vision Fund 2 and Liberty Strategic Capital became investors in LevelBlue. Steven Mnuchin, the former US Treasury Secretary and managing partner of Liberty Strategic Capital, joined LevelBlue's board.[2]
