NetSPI Raises $410 Million in Growth Funding from KKR


New investment to fuel the offensive security leader’s record-breaking growth and innovation pipeline

Minneapolis, MN – October 5, 2022 NetSPI, a leader in enterprise penetration testing and attack surface management, today announced that global investment firm KKR is increasing its investment in the company with $410 million in new funding. The growth investment validates NetSPI’s significant outperformance since KKR’s initial investment in May 2021 and will support NetSPI’s continued technology innovation, talent acquisition, and global expansion, as well as recapitalizing NetSPI’s first institutional investor Sunstone Partners.

Enterprises rely on NetSPI’s comprehensive suite of offensive security solutions – Attack Surface Management, Penetration Testing as a Service (PTaaS), and Breach and Attack Simulation – to uncover critical security gaps, minimize risk, and reduce the likelihood of a security incident. Founded in 2001, NetSPI leverages its ‘technology powered, human delivered’ penetration testing approach to improve the security of organizations globally, including the top financial institutions, largest cloud providers, leading healthcare organizations, and many of the Fortune 500.

“We are excited to double down on our investment in NetSPI to help build a differentiated leader in offensive cyber security,” said Jake Heller, Partner and Head of KKR’s Technology Growth team in the Americas. “We have been very impressed by the performance of the company and the exceptional execution by Aaron and his team over the past 18 months. We believe this is just the beginning of what we can accomplish together.”

“We’re both grateful and proud of the industry disruption we drove during our partnership with Sunstone Partners,” said Aaron Shilts, CEO at NetSPI. “As we look forward to this next chapter, NetSPI will continue to challenge the status quo in offensive security. With KKR’s support, we are well positioned to amplify our success building the best teams, developing new technologies, and delivering excellence, so that the world’s most prominent organizations can innovate with confidence.”

NetSPI has consistently outpaced growth forecasts. Over the past five years, the company has grown its revenue five-fold, exceeding 50 percent organic revenue growth in 2021 and 61 percent growth in 2022 to date. Key growth drivers include:

  • NetSPI’s Penetration Testing as a Service (PTaaS) delivery model, where human ingenuity and novel technologies intersect to create consistent, scalable, and efficient pentesting results.
  • The acquisition of Silent Break Security, which added additional offensive testing expertise and talent depth, along with innovative technologies that have expanded NetSPI’s global offerings.
  • The introduction of Attack Surface Management to identify and protect the unknown with continuous penetration testing and manual exposure triaging.
  • The NetSPI University training program which enables NetSPI to develop the next generation of cybersecurity talent through formal curriculum and hands-on labs and mentorship, resulting in the most comprehensive training and certification program in security testing.
  • Continuous advancement and innovation across all three technology platforms – ASM, Resolve, and AttackSim – to enable teams to deliver more accessible and impactful results.
  • Establishing strong teams in Canada, EMEA, and India as key component of the company’s global expansion efforts.
  • NetSPI’s ability to recruit and retain top industry talent. The company recently reached the milestone of more than 400 offensive security professionals globally.

“NetSPI continues its trajectory of strong, and accelerating, organic growth and profitability and we are excited about the opportunity to continue this momentum with further investments in technology, people, geographical expansion and strategic acquisitions,” said Ben Pederson, a Director on KKR’s Technology Growth team. “Penetration testing is an increasingly important and strategic aspect to any enterprise’s security posture and we believe NetSPI is a category defining player in the space through their best-in-class technology and PTaaS delivery model.  We look forward to supporting NetSPI’s continued growth on a global scale.”

“Following our investment in 2017, we’ve had the pleasure of working closely with NetSPI’s team as the company evolved and established itself as the high-growth, profitable security leader it is today, “said Gustavo Alberelli, Сo-Founder & Managing Partner at Sunstone Partners. “This transaction demonstrates that even during these turbulent times cybersecurity market leaders such as NetSPI will remain highly valuable – especially those providing mission critical solutions to global enterprise customers. We’ve enjoyed having KKR as co-investors since 2021 and look forward to watching NetSPI’s continued success in the future.”

This investment follows NetSPI’s most recent $90 million funding round from KKR and cybersecurity specialist investor Ten Eleven Ventures and comes from KKR’s Technology Growth strategy, which is dedicated to growth equity investment opportunities in leading high-growth technology companies in North America, Europe and Israel.

The transaction will close by the end of 2022, subject to customary regulatory approvals. Goodwin Procter LLP advised NetSPI on the transaction and Latham & Watkins LLP advised KKR.
