Israeli cloud security startup Dome9 Security Inc. has raised $16.5 million in a Series C funding round led by SoftBank Corp. along with a number of existing investors.

Under the deal, SoftBank will become the leading distributor of Dome9’s Arc cloud infrastructure security platform in the Japanese market. Founded in 2010, Dome9 offers a cloud firewall management service that uses patent-pending security automation tools to deliver a frontline security defense against newly discovered “zero-day” vulnerabilities and exploits. It also secures remote access and centralizes policy management.

The company said its Arc software as a service platform allows customers to simplify security operations and speed up compliance in their public and multi-cloud environments. Dome9 claims Arc is the only cloud security solution to offer native integration, enabled by application programming interfaces, with Amazon Web Services, Microsoft Azure and the Google Cloud Platform.

It also offers an agent-based approach that extends the platform to other public clouds and on-premises cloud deployments. The platform’s features include the ability to assess security posture, detect misconfigurations, implement model “gold standard” policies, protect against attacks and identity theft, and provide conformity to security best practices in the cloud.

“As enterprise adoption of the cloud continues to accelerate, there is a growing need for cloud-native solutions that simplify security operations and compliance,” SoftBank’s Director of Cyber Security Business Development Masayuki Motoshima said in a statement sent to SiliconANGLE. “Dome9’s strong traction in the enterprise market attests to the value the technology delivers and led to our decision to invest.”

Including the new round, Dome9 has raised $24.3 million to date. Previous investors include JAL Ventures, Lazarus Israel Opportunities Fund, Opus Capital, ORR Partners and Pinnacle. The company said it would use the new funding to capitalize on its business momentum by investing in research and development as well as expanding its sales and marketing team.
