Cybereason is an endpoint security company founded in 2012 by three veterans of Israel’s Unit 8200. After raising over $850 million including major investments from SoftBank, the company faced financial difficulties and was ultimately acquired by LevelBlue in November 2025. Cybereason achieved a 100% protection score in MITRE ATT&CK evaluations.
Platform Overview
The Cybereason Defense Platform provides AI-driven endpoint detection and response.
The MalOp (Malicious Operation) detection engine is Cybereason’s differentiator. Rather than alerting on individual events, the platform correlates related activities into comprehensive attack stories showing the full scope of multi-stage attacks.
Endpoint detection and response uses behavioral analytics and machine learning to detect unknown and advanced threats in real-time. The platform supports a 1:200,000 analyst-to-endpoint ratio through automation.
Extended detection and response integrates across endpoints, mobile devices, cloud platforms, and applications. The platform provides 65+ integrations with identity, workspace, network, and cloud tools.
Predictive ransomware protection detects ransomware behavior patterns before encryption begins. The platform can automatically isolate affected endpoints to prevent spread.
Rise and Fall
Cybereason was once valued near $5 billion and planned an IPO in 2021. Economic conditions forced cancellation of those plans in 2022, leading to three rounds of layoffs affecting over 300 employees.
By 2023, valuation had dropped to $300-400 million, a 90%+ decline. CEO Lior Div was replaced by SoftBank-appointed Eric Gan in April 2023. A planned merger with Trustwave was announced in November 2024 but terminated in March 2025 amid investor disputes.
LevelBlue Acquisition
In October 2025, LevelBlue announced acquisition of Cybereason, completing the deal in November 2025. The combination creates a comprehensive managed security platform combining Cybereason’s XDR with LevelBlue’s MDR capabilities.
Key Customers
Cybereason served customers in 40+ countries across retail, financial services, and government sectors. The platform is available on Google Cloud Marketplace.
Leadership
Manish Narula serves as CEO since March 2025, also serving as CFO. He previously held roles at Microsoft and ARM. Founders Lior Div, Yonatan Striem-Amit, and Yossi Naar all served in Israel’s Unit 8200 intelligence unit.
