Lockheed Martin will integrate the Cybereason Detection and Response Platform.
Security startup Cybereason has raised $25m from a group of investors including Spark Capital and Lockheed Martin, along with its existing supporter Charles River Ventures (CRV).
Cybereason had earlier raised $4.6m from CRV in February 2014. The latest round brings the company’s total funding to $29.6m.
Apart from participating in Series B funding round, Lockheed Martin has agreed to integrate the Cybereason Detection and Response Platform into several of its cyber security offerings.
The move will see Lockheed Martin implement Cybereason’s platform across more than 120,000 internal endpoints and servers.
Lockheed Martin Commercial Cyber Services director Rich Mahler said: "The Cybereason platform is an outstanding complement to the tradecraft and technologies Lockheed Martin uses every day to defend our network and our clients.
"Its real-time detection and attack tracing capabilities enable us to effectively leverage threat intelligence and provide our government and commercial customers with a calculated, strategic approach to cyber defence.
"That’s why in addition to deploying Cybereason’s platform across more than 120,000 internal endpoints and servers, we also partnered with it and participated in this latest round as a strategic investor."
The Cybereason platform reduces the time taken to identify and confirm a breach and connects isolated parts of malicious activity.
Cybereason CEO Lior Div said: "The ongoing parade of mega breaches has made cyber security a top business issue, but detecting attacks on large, complex corporate networks is extremely difficult to do.
The Cybereason platform not only automates real time attack detection, it presents the full attack story in a way that security employees and business stakeholders can easily understand and use."
The Cybereason platform was founded by members of the Israeli intelligence agency’s elite cyber security Unit 8200.
Headquartered in Cambridge, Massachusetts, Cybereason currently has about 20 customers across various industries.
Spark Capital general partner Santo Politi said: "Cybereason believes that a breach is inevitable and that a determined hacker will eventually bypass even the best protection solutions.
"The platform provides a holistic approach to security from identifying attackers’ activities once they are inside the organisation to isolating incidents to business information and continuity."
