Israeli anti-fraud and cybersecurity specialist ThetaRay has locked in a $5 million investment from Chinese e-commerce titan, Alibaba. The investment is part of a larger $20 million round-in-progress that includes participation from General Electric, Jerusalem Venture Partners, and Poalim Capital Markets, along with other investors.

ThetaRay’s technology specializes in detecting and preventing advanced persistent threat (APT), which is a type of network attack designed to steal information rather than simply destroy or damage a network or organization. The company’s solution also works against “zero-day” attacks—attacks via security vulnerabilities unknown to the vendor—within minutes of detection.

ThetaRay this week announced a new partnership with PwC, a global advisory firm specializing in audit and assurance, tax, and consulting services. The Global Joint Business Relationship will make ThetaRay technology a part of PwC’s advanced data-analytics service, and is PwC’s first with an Israeli cybersecurity firm.

“Using ThetaRay’s technology, we can help businesses utilize existing big data to discover opportunities, mitigate risks and increase revenues and profitability,” said Yaron Blachman, PwC Israel’s leader of technology and forensics consulting.

Founded in April 2013, with offices in Israel and the U.S., ThetaRay demonstrated its fraud and credit risk solution at FinovateFall 2015. The company was named “Most Innovative Industrial Internet Technology” at the Minds + Machines 2015 Conference sponsored by General Electric.
