As businesses begin to rely more and more on various cloud services, there is now a need for a data privacy and security solution that can bridge the gap between competing cloud services that don’t always play nice with each other. Sonrai Security is attempting to fill that need and it was rewarded with $18.5 million in Series A Funding from Polaris Partners and TenEleven Ventures.

Brian Dowling tells more about Sonrai Security in this excerpt from a report in Xconomy:

Instead of building walls around the perimeters of a data center, Sonrai’s system is built on identifying each bit of data and every user that has access. The product sits on top of what could be hundreds of different cloud accounts to track the data and users. From there, it can start to send alerts when users’ patterns change, or the cloud account is compromised by an external attack. The system also translates all the varied terms and systems of Amazon Web Services, Microsoft Azure, and other cloud services, so users can make a single request for information about data or a user, and it’s fulfilled across the different services.

It’s unclear how Sonrai’s control platform differs from others that work across multiple cloud services. VMware (NYSE: VMW) and Cisco (NYSE: CSCO) offer hybrid cloud monitoring systems with security components, as do a crop of startups that seem to be developing competing tools, including Canadian firm Embotics, San Francisco-based Scalr, and Santa Barbara, CA-based Right Scale.

Sonrai’s system aims to tackle how companies audit their data to comply with new data privacy laws, including the European Union’s General Data Protection Regulation. The newly launched company has a lot of work ahead of it, (Company founder Brendan) Hannigan says, with plans to develop machine learning tools to give users better intelligence about their data on the cloud.
