Security start up Bracket Computing has been awarded $45m in a Series C investment round to develop its system for making content safe on the cloud.

Bracket’s Computing Cell technology works by encapsulating content in cell in order to secure it. The enveloped data and applications can then travel in safety across multiple cloud environments, according to its inventors. The Cell technology simplifies the increasingly complex issue of cloud management by consolidating security, networking and data management into a single construct.

The cell can run across multiple public clouds and in a customer’s own data centre. The cell structure also brings consistency to the cloud, as it protects client apps from the performance changes that can occur in cloud computing.

Customers hold the digital keys to their data, which is encrypted. Bracket runs a service that reserves hardware at cloud providers when necessary and distributes the data across multiple machines to smooth performance and improve speed.

The founders, Tom Gillis and Jason Lango, have a pedigree in Internet security having created Ironport Systems’ anti-spam hardware range, which was bought by Cisco Systems 2007 for $830 million. In 2011 they founded Bracket to solve the new security problems created by the cloud.

“Imagine if you could encapsulate your most sensitive applications, data and services and run them securely across hyperscale public clouds and your private cloud, while ensuring consistent security controls and data management,” said Lango, “this is what a Bracket Computing Cell allows. It enables an enterprise without boundaries, without sacrificing security and control.”

The funds will finance a global roll-out said Bracket CEO Tom Gillis. The data centres of the finance sector are an immediate target, but the technology applies to all large corporations, said Gillis. “Financial firms need to remain technology leaders. We’re working with some of the very largest as we define the blueprint for the data centre of the future.”
