Company History and Business Evolution

Cybereason was founded in 2012 by former Israeli Defense Forces intelligence officers Lior Div, Yossi Naar, and Yonatan Striem-Amit, who brought a military-grade approach to cyber defense. The company quickly gained traction with its MalOp (Malicious Operation) detection engine, which revolutionized how security teams visualize and respond to attacks. Cybereason UK was established shortly thereafter to serve the European market, with its headquarters in London’s tech hub. Over the years, Cybereason UK has experienced phenomenal growth, marked by several key milestones: In 2016, the company secured $59 million in Series C funding from SoftBank Corp., valuing it at over $1 billion. By 2019, Cybereason had raised over $400 million in total funding, including investments from SoftBank, Hexaware, and others. The UK subsidiary expanded rapidly, opening additional offices in Manchester and Edinburgh to support its growing client base. A significant milestone was the launch of the Cybereason XDR platform in 2020, which integrated endpoint, network, and cloud telemetry into a single unified console. The company also acquired threat intelligence firm InQuest in 2021 to bolster its data enrichment capabilities. In 2022, Cybereason achieved unicorn status with a valuation exceeding $3 billion, and the UK arm contributed substantially to this success through strategic partnerships with MSPs and system integrators. The company’s evolution from a startup to a global cybersecurity powerhouse has been driven by continuous innovation, a relentless focus on customer outcomes, and a culture of collaboration. Cybereason UK has also played a pivotal role in defending critical UK infrastructure, including the NHS and financial institutions, during high-profile cyber attacks. Today, Cybereason UK employs over 500 professionals across multiple disciplines, making it one of the largest cybersecurity employers in the region. The company’s journey is a testament to the power of combining military-grade discipline with entrepreneurial agility.
