San Francisco, March 27, 2018 – Kenna Security, a leader in predictive cyber risk, announced today that it has secured $25 million in Series C funding. Bessemer Venture Partners led the round, with participation from U.S. Venture Partners, Costanoa Ventures, PeakSpan Capital, Hyde Park Angels and OurCrowd. Alex Ferrara, partner at Bessemer Venture Partners, will join Kenna’s board of directors.

“Strong market demand has validated Kenna’s risk-based approach to vulnerability management with CISOs, security teams, and IT operations staff leveraging Kenna’s machine learning and data science to proactively manage cyber risk,” said Karim Toubba, CEO of Kenna Security. “Kenna sees a world where teams work in collaboration to quickly and easily measure risk, prioritize remediation, and make a substantive difference in efficacy across the global attack surface and this investment is an endorsement of what we have achieved and our vision for the future.”

The company will use the funds to continue its strong growth and momentum, investing to attract new talent, expand its sales capabilities, and continuing to drive innovation.  

“Kenna is pioneering a new category of enterprise security to solve a pain point that is high on the priority list for CISOs, Security, and IT Ops teams, and we believe that Kenna is best situated to maintain its lead in the emerging vulnerability prioritization market,” said Alex Ferrara, partner at Bessemer Venture Partners and member of the board of directors at Kenna Security. “Kenna’s risk-based approach offers customers a way to cut through the volumes of data and threat reports to get to actionable information. We’re excited to invest and support Kenna as they transform the way that enterprises align around cyber risk.”

One of the first venture firms to invest in cyber security startups, Bessemer has invested in more than 45 leading cyber security startups over the past two decades. Recent successful cyber security investments include: LifeLock (acquired by Symantec), Postini (acquired by Google), Tripwire (acquired by Belden), iSight (acquired by FireEye).

As organizations shift to a risk-based approach to vulnerability management, many of the world’s most trusted brands have turned to Kenna Security, including elite members of the Fortune 100, to manage cyber risk at scale, preparing them to confront the volume and diversity of contemporary cyber threats. For the third year in a row, Kenna’s sales more than doubled in 2017 and the number of organizations using the Kenna Security Platform grew by more than 60 percent to more than 300 customers worldwide.
