The American defense contractor Lockheed Martin was so impressed with the protection system of the Israeli company Cybereason that Lockheed not only recommended Cybereason’s software to its customers, but also invested $25 million in the company, The Times of Israel reported Thursday.

Several months ago, Lockheed checked out Cybereason’s protection system, and liked it enough to recommend it to others, “after they compared our solution against a dozen others from the top industry players,” CEO Lior Div told The Times of Israel. The series B funding round was led by Spark Capital, with participation from existing investor CRV.

In fact, Lockheed was so impressed with the results they got from Cybereason that they began offering it to their own customers – among them most of the top Fortune 100 companies, and the US federal government. CyberReason is now the security system recommended by Lockheed to its customers for protection from a wide malware and hack attacks.

“The Cybereason platform is an outstanding complement to the tradecraft and technologies Lockheed Martin uses every day to defend our network and our clients,” Rich Mahler, director of commercial cyber services at Lockheed Martin, told the Times. “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 defense. In addition to deploying Cybereason internally and partnering with it, we also participated in this latest round as a strategic investor.”

In addition to being a major defense contractor, Lockheed is also one of the top IT vendors to the U.S. federal government.

Lockheed opened a research and development facility in Beer Sheva last year that is focused on cybersecurity.
