Container monitoring and security startup Sysdig scored $68.5 million in a Series D funding round, bringing its total to $121.5 million. Insight Venture Partners led the round. Previous investors Bain Capital Ventures and Accel also participated.

The San Francisco-based startup, founded in 2013, launched its Secure product in October 2017. It is built on Sysdig’s Falco open source container security project, and it includes support for Kubernetes, Docker, Amazon Web Services (AWS), Elastic Compute Cloud (EC2), and Mesos.

In June, the company rolled out version 2.0. This added vulnerability management, more than 200 compliance checks, and security analytics to cloud-native environments and microservices for enterprise customers.

Dozens of Global 2000 enterprises are Sysdig customers, according to the company. It says these include financial institutions, media companies, cable companies, technology companies, and government agencies.

In a blog post, Sysdig CEO Suresh Vasudevan outlined the company’s three investment priorities for the Series D funding.

“First, to invest aggressively in our technology platform as we look to extend our leadership in container security and monitoring,” Vasudevan wrote. “Second, to invest aggressively in our sales and marketing and customer success initiatives as we look to build a thriving community of happy customers and users. Third, to continue expanding our team of talented employees that are passionate about enabling our customers to run reliable and secure containers and microservices.”

It’s been a busy year for the container security startup, which has seen rapid growth over the past 12 months. Downloads of Sysdig Falco have roughly tripled during this time period, and active users of the Sysdig software-as-a-service (SaaS) offerings have grown nearly six times year over year.

Last month Sysdig opened a second headquarters in Raleigh, North Carolina. In addition to the Raleigh and San Francisco headquarters, it also has offices in Belgrade and London.

Despite the company’s momentum — and overall momentum in the container security space — Vasudevan declined to comment on the company’s plans for an initial public offering (IPO).

It has been a hot year for enterprise software IPOs, however, and several of these newly public companies focus on cybersecurity.

Security startup Tenable raised $288 million in its July IPO. Zscaler and Carbon Black also completed successful IPOs with Zscaler raising $192 million and Carbon Black raising $152 million.
