San Francisco — April 25, 2017 — Twistlock, the leading provider of cloud container security solutions, today announced it raised $17 million in Series B funding, led by Polaris Partners, designed to support continued innovation and market leadership in the container security space. Twistlock’s venture capital investment to date totals $30 million. In addition to new lead investor Polaris Partners, existing investors YL Ventures, TenEleven and Rally Ventures participated in the round, and Brendan Hannigan of Polaris has joined the Twistlock Board of Directors as Chairman.

“As containers gain mainstream momentum and cloud-native applications surge, practices such as DevOps culture, continuous delivery, cloud development and containerization require a reinvention of security,” said Brendan Hannigan, Twistlock chairman and venture partner at Polaris Partners, “Twistlock has leapt to the leadership of container security by delivering rapid innovation and customer growth and is spearheading new ways to secure applications which address persistent flaws in old security solutions that have haunted customers for years.”

Announced earlier this month, the release of Twistlock 2.0 brings enhanced visibility and compliance to containerized environments and was built to handle even the most stringent of enterprise security requirements. Twistlock’s unique approach to application security uses machine learning to automatically create and enforce security models, giving developers the agility they need to deliver software in the modern world.

Twistlock’s Series B funding continues strong momentum for the company. Since the release of Twistlock 1.0 in November 2015, Twistlock’s customer base has grown over 325 percent, with over 40 customers worldwide as of early 2017. The company opened its Portland, OR office in Q4 2016, which has experienced more than 200 percent growth in the first few months of 2017 as the company continues to scale with offices in New York, Portland, San Francisco and Herzylia, Israel. In addition to this global expansion, Twistlock continues to demonstrate its commitment to industry leadership by collaborating with industry partners and NIST on developing recommendations for container security.

“We are pleased to bring Polaris and Brendan’s expertise into the fold, especially given his track record of leadership success both in the security startup scene as well as significantly scaling the security practice at IBM,” Ben Bernstein, CEO and co-founder at Twistlock. “This investment and partnership with all participants in the round validates Twistlock’s success in product delivery and customer adoption, while providing us instrumental support as we continue to scale our team and deliver innovative security solutions.”
