ZeroFox Raises $40 Million in New Financing for Rapid Global Expansion and Product Innovation

Social Media and Digital Risk Monitoring Market Leader Completes Series C Investment Round, Bringing Total Funding to $88 Million. New Investment Will Help Drive Global Expansion and Product Advancement.

BALTIMORE, MD – July 12, 2017 – ZeroFox, the social media and digital risk monitoring market leader, today announced that it has closed $40 million in funding led by Redline Capital Management and Silver Lake Waterman, Silver Lake’s late stage growth capital fund. The round also includes existing investors NEA, Highland Capital Partners and Core Capital. The company will use the funds to drive rapid global expansion and continued product innovation. Including the new Series C, ZeroFox has received a total of $88 million in funding to date.

In conjunction with the round, ZeroFox also announced that Alastair Cookson, Partner at Redline Capital Management, has joined the company’s Board of Directors. Bringing two decades of global emerging market experience and a track record of successful security and technology investments, Mr. Cookson will help drive ZeroFox’s accelerated expansion into new, worldwide markets.

“With the mass adoption of social media, organizations of all sizes are contending with new threats that do not show up in their existing monitoring, let alone defense and remediation capabilities,” said Alastair Cookson, Partner, Redline Capital Management. “We back market leaders, and we searched throughout the world to find the organization that was best suited to address these next generation security challenges. ZeroFox’s platform enables organizations to gain visibility and achieve control of their external assets in real-time. We are excited to support them down their path of rapid growth.”

“Social media is an important fabric that connects businesses with their customers. Like other forms of digital communication, it is being rapidly leveraged for targeted attacks,” said Shawn O’Neill, Managing Director, Silver Lake Waterman. “Their platform has been recognized as the category leader, and we are excited to partner with ZeroFox.”

Business and personal use of social media have blurred over time, creating new enterprise protection challenges for organizations. Using artificial intelligence and its patented enterprise-grade platform, ZeroFox protects organizations from targeted phishing attacks, social media account compromise, data exfiltration, brand hijacking and more. Using a patented programming language called FoxScript, ZeroFox exposes both its artificial intelligence backend and fully extensible APIs. FoxScript was designed in tandem with our customers and partners, and without any programming experience required, it quickly and easily enables customers to modify our extensive library of protection policies. ZeroFox was Top-Ranked in Customer References by the Forrester Digital Risk Monitoring Wave.

“Organizations around the globe are quickly realizing the risks associated with using external social and digital platforms for business communication,” said James C. Foster, Chairman and CEO, ZeroFox. “ZeroFox is dedicated to helping customers stay ahead of targeted attacks against their businesses. Threats initiated by today’s attackers affect everyone regardless of an organization’s size, industry or location. This round of funding enables us to accelerate product innovation, enforce our intellectual property and expand our global presence, ensuring that all organizations are protected from targeted attacks.”
