About Cybereason
Cybereason was founded in 2012 by Lior Div, Yonatan Striem-Amit, and Yossi Naar, veterans of Israeli intelligence cybersecurity units, based on the observation that traditional antivirus software, designed primarily to detect known malicious files based on signatures, was poorly equipped to detect more sophisticated attacks that use novel techniques, living-off-the-land tactics that abuse legitimate system tools, or multi-stage attack campaigns that unfold gradually across an organization's network over an extended period rather than through a single detectable malicious file.
Cybereason's platform provides endpoint detection and response (EDR) technology that continuously monitors activity on an organization's computers and servers, using behavioral analysis rather than only signature-based detection to identify patterns of activity consistent with an attack in progress, even when the specific tools or techniques being used haven't been seen before. A key differentiator in Cybereason's approach has been its emphasis on presenting security analysts with a consolidated view of an entire attack, sometimes called a "MalOp" or malicious operation, that connects related individual alerts and events across an attack's full timeline and scope into a single coherent narrative, rather than requiring analysts to manually piece together potentially hundreds of disconnected individual alerts to understand what's actually happening during a sophisticated, multi-stage attack. The company has expanded its platform into extended detection and response (XDR), broadening monitoring beyond just endpoints to include network, cloud, and identity data sources for a more comprehensive view of potential threats across an organization's full environment. Cybereason has raised very substantial venture funding from investors including SoftBank Vision Fund and CRV, reaching a valuation exceeding $3 billion at its peak, though the company, like several venture-backed cybersecurity firms that raised large rounds during the height of the 2018-2021 funding boom, has navigated subsequent funding challenges and valuation markdowns as growth expectations recalibrated, competing with other EDR and XDR vendors including CrowdStrike, SentinelOne, and Microsoft Defender.
