Aqua Security Software Ltd.’s latest funding round shows there’s still a big appetite for container security tools in the enterprise.

The company today said it has just raised $30 million in a Series D round of funding, bringing its total amount raised to more than $130 million. Greenspring Associates led the latest round, which also saw the participation of existing investors Insight Partners, Lightspeed Venture Partners and TLV Partners.

Aqua Security has made its name selling tools that can help to protect container-based, cloud-native and serverless applications from malware and malicious attacks. Its main product is its Cloud Native Security Platform, which gives developers the ability to automate and improve container security and compliance posture, monitor usage and control user access.

The platform also gives users full visibility into container activity, allowing them to detect and prevent attacks and suspicious activity in real time. By integrating with the application lifecycle and orchestration tools, Aqua’s platform can even automate security processes while helping to enforce regulatory compliance.

Those kinds of capabilities are increasingly in demand in an age when enterprises are becoming more reliant on software containers, which are used by developers to build apps that can run on any computing infrastructure. They’re equally sought after by developers of serverless apps, where the management and allocation of servers and resources are completely managed by cloud providers.

Such is the demand that Aqua claims to have more than doubled its revenue in the last 12 months, to an undisclosed amount, with big customers in the finance, energy, aerospace, media, retail, pharmaceutical and hospitality sectors using the company’s tools.

“We are seeing customers continuing their move towards cloud-native technologies, often accelerating deployments as a way to enhance their agility in these unpredictable times,” said Dror Davidoff, Aqua’s co-founder and chief executive officer. “Security remains a key enabler of these initiatives.”

The company has been busy expanding its capabilities too, acquiring a smaller firm called CloudSploit LLC in November to add cloud security posture management features to its platform.

Davidoff told SiliconANGLE in an interview that the new funds will be used to support continued growth in the company’s field organization. It will also use some of the money to invest in product innovation, he said.

Today’s round was notably a lot less than the $62 million that Aqua Security raised in its previous, Series C round of funding in April 2019. Davidoff said the company had been careful in its approach to managing its cash as it looks to build a sustainable long-term business.

“The size of this round reflects what we believe are the needs of the business going forward, and based on our strong growth in 2019 and the first quarter of 2020, places a significantly higher valuation on Aqua than a year ago,” Davidoff said.
