Cybersecurity firm Cybereason announced today a $59 million Series C that was led by SoftBank.

In addition to SoftBank, existing investors CRV (Charles Rivers Ventures) and Spark Capital took part in the round. SoftBank, a customer of Cybereason, will team up with the startup for a joint offering in Japan that’s designed to help organizations defend against advanced attacks.

With corporate breaches occurring continually (Dow Jones being the latest victim), Boston-based Cybereason has had some success in fundraising. In May, it raised a $25 million Series B that was led Lockheed Martin. To date, Cybereason has raised $88.1 million.

Cybereason uses big data, behavioral analytics, and machine learning to unmask complex cyber-attacks that are designed to evade traditional defenses. It automates the investigation process and connects isolated malicious events to create a visual representation of an attack. The platform is available as an on-premises offering, or as a cloud-based service.

Using its automated behavioral analysis, Cybereason recently discovered a new attack targeting Microsoft Outlook Web Application (OWA).

Cybereason was founded in 2012 by members of an Israeli intelligence agency security team. The company has 80 employees, with about half located in Boston and Tel Aviv. Its competitors include Bit9, CounterTrack, Crowdstrike, and Tanium.
