Container security startup Aqua Security secured $62 million in a Series C funding round, bringing its total amount raise to more than $100 million. The round was led by Insight Partners and contributed to by existing investors Lightspeed Venture Partners, Microsoft’s Venture Fund M12, TLV Partners, and Shlomo Kramer.

Aqua’s CEO and co-founder Dror Davidoff said that because the “cloud native technology stack is still very dynamic,” the money will be primarily used to invest in “functional innovation and support for emerging platforms." That, and it will scale its field infrastructure on a global basis, focus on sales and customer success, and both directly and through its partners program increase its investments in market development.

The platform is “roughly” on a quarterly release schedule for major updates, he said.

In March, the startup rolled out upgrades to its cloud-native security platform. The 4.0 release had two main upgrades: a new chain of controls to scan functions across any number of clouds and a set of tighter controls to secure Linux hosts that run containers. It also included continuous integration/continuous delivery (CI/CD) plug-ins, sensitive data assessment, functions assurance, and functions anomaly detection.

The next release is scheduled for June and will expand Aqua’s serverless and compliance features, “as well as a few surprises we aren’t ready to share quite yet,” said Davidoff.

Aqua released its security platform in 2016. It supports container stacks from Docker, Kubernetes, Mesos, CoreOS, Microsoft, Red Hat, and VMware, and it supports on-premises deployments on Amazon Web Services (AWS), Microsoft Azure, Google Cloud Platform, and other public clouds.

In the four years since its launch, Aqua has made quite a splash and has seen a lot of growth in the container and container security space.

“Four years ago, the space was mostly about Docker, and very few customers were deploying containers in production,” said Davidoff. “In the past 2 years we’ve seen the emergence of Kubernetes as a standard for orchestration which was a key driver around which other technologies aligned, with more diverse environments, including OpenShift, Cloud Foundry, and serverless technologies on all the major cloud platforms.”

Going forward, the startup plans to keep scaling and meeting the demands of new cloud-native technologies. “Any technology that shows early signs of enterprise adoption in the cloud native space will be something we’ll want to secure,” he said. “Looking at the current technologies that are gaining traction with our customers, enhancing support for service meshes (in plural) would be something one might expect [in the future].”

In the past year, Aqua has added protection for serverless containers and functions, with more on the horizon, Davidoff noted.
